The City of San Luis Obispo operates a Water Reclamation Facility (WRF) that serves
the entire City, California State Polytechnic University and the County airport. This
represents a service population of over 40,000 and an average annual flow of 4.5 MGD.
The advanced tertiary facility includes: bar screens, aerated grit removal, primary
clarification, biofiltration, secondary clarification, activated sludge, final clarification,
dissolved air flotation thickening, filtration, cooling, flow equalization, disinfection and
dechlorination. The WRF discharges to San Luis Obispo Creek, an intermittent
freshwater stream. The City also administers an approved pretreatment program that has
3 permitted significant industries and over 300 smaller permitted facilities. These
facilities include but not limited to: restaurants, photoprocessers, automotive repair, dry
cleaners and hospitals. Attachment A includes a location map and schematic flow
diagram. Please note that the flow diagram does not include the belt press or filtration.
All sludge is digested anaerobically using three digesters arranged in a series. Digesters
#1 and #2 are heated and mixed while #3 functions more as a holding tank. During the
drier parts of the year the sludge is placed in drying beds, dried and stockpiled to await
disposal, a belt press is used for the remainder of the year. The belt press produces cake
that is approximately 14-16% solids; this is also stockpiled before reclamation.
At present the City collects samples for metals bimonthly. All samples are collected,
handled and tested according to EPA methods. Pollutant concentration levels and vector
reduction both meet class A sludge requirements while pathogen reduction meets 40 CFR
503 “Processes to Significantly Reduce Pathogens” (PSRP) definition or class B
requirement. Overall the City produces a Pollutant Concentration or “PC” product.
Pollutant concentration, pathogen reduction and vector reduction methods are described
in detail below.
Recently during an internal review of the 503 regulations, the City’s National Pollutant
Discharge Elimination System (NPDES) permit Monitoring and Reporting Program
(M&RP) and the recent reminder notification form EPA, it was determined that the City
was not required to continue sampling for pollutants on a bi-monthly basis because the
City has been using a composter that mixes the biolsolids with other agencies. Per the
503 regs the frequency of monitoring applies to the composter, not the generator and the
City is required to sample as often as its NPDES permit and its agreement with the
composter stipulates. The City has adjusted its sampling schedule for pollutants and is
working closely with its composter, Engel and Gray, to ensure compliance and adequate
sampling for the program. Next year’s annual report will reflect these sampling changes.
Digester #2 was emptied, cleaned and repaired in 2006, beginning in late May and
coming back on-line in late December. During inspection it was found that the mixer
was in disrepair and replaced, along with some minor coating repair and pipe
replacement. The digester was in generally good condition. Although detention times
were shortened, VSRs did not drop below 38%. Temperatures have not been reported for
the period the digester was under repair.

The City has completed its energy project that utilizes digester gas to generate electricity
and provide heat for the digesters. The project provides significant energy savings for the
City’s WRF while offering an efficient and effective heating source for the digesters.
Back-up systems guarantee adequate heating and mixing at all times. Since operating the
system, the City has found it to be more efficient at heating the digesters than using the
boiler.
The City’s biosolids are mixed with biolsolids from other agencies and green waste
materials, placed in open windrows that are mechanically aerated and turned periodically.
Windrows are monitored daily for temperature and moisture until proper composting and
pathogenic destruction has been achieved, per the 40 CFR 503 regulations. City staff
performed an inspection of the facility in 2005 and found it to be a well managed and
compliant facility using industry standard methods for monitoring and managing their
composting operations. Finished compost is then sold to agricultural, horticultural and/or
landscape operations, some has been sold back to the City as a soil amendment. Engel
and Grey are a permitted facility that operates in Northern Santa Barbara County.
As previously reported, San Luis Obispo County Environmental Health has developed an
interim biosolids ordinance that prohibits land application of biosolids, except for
amounts that have been historically applied in the County, until the development and
adoption of a permanent ordinance. The interim ordinance offers some County control
over biosolids projects prior to development and adoption of a permanent ordinance. The
interim ordinance was first heard by the San Luis Obispo County Board of Supervisors in
November of 2003 and had its second hearing in February 2004 and was adopted in
March 2004. Because of County staff workload issues and no imminent need for a
permanent ordinance, the interim ordnance, which expired in summer of 2006, was
renewed for a 5 year period as a place holder until adequate County staff resources
become available and/or a need for a permanent ordinance is recognized.
The permanent biosolids ordinance for San Luis Obispo County has been drafted and
comments were due to San Luis Obispo County Environmental Health on January 31,
2004. The City, and others, submitted their comments and no other activities have
occurred since that time. As discussed previously, there is no plan to more forward with
a permanent ordinance.
The permanent ordinance is based on the federal 40 CRF 503 regulations, the State of
California’s General Discharge Order and recommendations from the San Luis Obispo
County biosolids task force (working group). This working group met 20 times over 20
months in 2000 and 2001 and prepared six primary recommendations for the San Luis
Obispo County Board of Supervisors regarding oversight, management and disposition of
land application of biosolids in San Luis Obispo County. The working group’s
recommendations have been presented to other County advisory bodies in spring of 2002,
and were later presented to the San Luis Obispo County Board of Supervisors.

POLLUTANT CONCENTRATIONS
Pollutant concentrations are listed in attachment B. All pollutants are less then the table 3
[40 CFR 503.13] pollutant concentrations. Samples are composites of recently pressed
sludge prior to removal for stockpiling on-site or hauling. Sludge samples calculated for
dry weight using the methodology described in EPA’s “Preparing Sewage Sludge for
Land Application or Surface Disposal”, EPA publication 831B-93-002a, to determine a
true dry weight. Samples are analyzed by a contract lab that follows federal regulations
for sample handling, analysis and reporting, is state DOHS certified and has submitted its
QC/QA manual to the City.
PATHOGEN REDUCTION
The City is using alternative 2 [40 CFR 503.32(b)(3)], anaerobic digestion, for class B
sludge. The average annual temperatures and detention times during the reporting period
for the digesters was 31.8 C for 57.8 days at 18,885 gpd feed. Flows vary between
16,300 gpd to 21300 gpd average monthly flow. Sludge flows and temperature are
measured and recorded daily. At present digester #1 has a average detention time of 28.1
days @ 29.6 C, digester #2 is 15.8 days @ 33.9 C and digester #3, has a detention time of
13.9 days, unheated, but maintains digester's #2’s temperature. These detentions times
and temperatures ensure adequate pathogen reduction. Attachment C shows monthly
averages for digester temperatures, flows and detention times.
“I certify, under penalty of law, that the pathogen requirements in 503.32(b)(3) have been
met. This determination has been made under my direction or supervision in accordance
with a system designed to assure that qualified personnel properly gather and evaluate the
information used to determine that the pathogen requirements have been met. I am aware

VECTOR ATTRACTION REDUCTION
The City is using alternative 1 [40 CFR 503.33(b)(1)], 38% Volatile Solids Reduction
(VSR) for vector attraction reduction. VSRs are tested almost weekly resulting in an
annual average of 59.4% VSR. Total VSRs ranged from 69.2% to 17.7%, 1 out of 49
samples were lower then the 38% target value. These samples are probably analytical or
sampling errors because samples taken before and after them are well above the 38%

target value. The target value for operation of the digesters is to achieve at least 38%
VSR 100% of the time. Attachment D shows the results of the WRF's VSR sampling.
All VSR analytical work is at the WRF laboratory using EPA approved methods and
following standard methods for sampling and testing. Raw sludge, flows between the
digesters and total (final) VSRs are analyzed every week.
"I certify, under penalty of law, that the vector attraction requirements in 503.33 have
been met. This determination has been made under my direction or supervision in
accordance with a system designed to assure that qualified personnel properly gather and
evaluate the information used to determine that the vector attraction requirements have
been met. I am aware that there are significant penalties for false certification, including
the possibility of fine or imprisonment”

City of San Luis Obispo - 2008 Annual Biosolids Report.
Februarv 13.2008
The City of San Luis Obispo operates a Water Reclamation Facility (WRF) that serves
the entire City, California State Polytechnic University and the County airport. This
represents a service population of over 40,000 and an average annual flow of 4.5 MGD.
The advanced tertiary facility includes: bar screens, aerated grit removal, primary
clarification, biofiltration, secondary clarification, activated sludge, final clarification,
dissolved air flotation thickening, filtration, cooling, flow equalization, disinfection and
dechlorination. The WRF discharges to San Luis Obispo Creek, an intermittent
freshwater stream. The City also administers an approved pretreatment program that has
4 permitted significant industries and 296 smaller permitted facilities. These facilities
include but are not limited to: restaurants, photoprocessers, automotive repair, dry
cleaners and hospitals. Attachment A includes a location map and schematic flow
diagram. Please note that the flow diagram does not include the belt press or filtration.
All sludge is digested anaerobically using three digesters aranged in a series. Digesters
#l and #2 are heated and mixed while #3 functions more as a holding tank. During the
drier parts of the year the sludge is placed in drying beds, dried and stockpiled to await
shipment for compost. A belt filter press is used for the remainder of the year. The belt
filter press produces cake that is approximately 14-16% solids; this is also stockpiled
before shipment for compost.
Internal review of the 503 regulations, the City's National Pollutant Discharge
Elimination System (NPDES) permit Monitoring and Reporting Program (M&RP) and
the recent reminder notification form EPA, it was determined that the City was not
required to continue sampling for pollutants on a bi-monthly basis because the City has
been using a composter that mixes the biolsolids with other agencies. Per the 503
regulations the frequency of monitoring applies to the composter, not the generator and
the City is required to sample as often as its NPDES permit and its agreement with the
composter stipulates. The City has adjusted its sampling schedule for pollutants and is
working closely with its composter, Engel and Gray, to ensure compliance and adequate
sampling for the program.
The City's biosolids are mixed with biosolids from other agencies and green waste
materials, placed in open windrows that are mechanically aerated and tumed periodically.
Windrows are monitored daily for temperature and moisture until proper composting and
pathogenic destruction has been achieved, per the 40 CFR 503 regulations. City staff
performed an inspection of the facility in 2005 and found it to be a well managed and
compliant facility using industry standard methods for monitoring and managing their
composting operations. Finished compost is then sold to agricultural, hor-ticultural and/or
landscape operations, some has been sold back to the City as a soil amendment. Engel
and Grey are a permitted facility that operates in Northern Santa Barbara County.
A capital project to drain, clean and inspect Digester #1 is slated to be completed during
the 2008-09 budget year. Digester #i was last cleaned, inspected and repaired in July
2002.
City of San Luis Obispo - 2008 Annual Biosolids Report.
Februarv 13.2008
The City has completed its energy project that utilizes digester gas to generate electricity
and provide heat for the digesters. The project provides significant energy savings for the
City's WRF while offering an efficient and effective heating source for the digesters.
Back-up systems guarantee adequate heating and mixing at all times. Since operating the
system, the City has found it to be more efficient at heating the digesters than using the
boiler.
As previously reported, San Luis Obispo County Environmental Health has developed an
interim biosolids ordinance that prohibits land application of biosolids, except for
amounts that have been historically applied in the County, until the development and
adoption of a permanent ordinance. The interim ordinance offers some County control
over biosolids projects prior to development and adoption of a permanent ordinance. The
interim ordinance was first heard by the San Luis Obispo County Board of Supervisors in
November of 2003 and had its second hearing in February 2004 and was adopted in
March 2004. Because of County staff workload issues and no imminent need for a
permanent ordinance, the interim ordnance, which expired in summer of 2006, was
renewed for a 5 year period as a place holder until adequate County staff resources
become available and/or a need for a permanent ordinance is recognized.
The permanent biosolids ordinance for San Luis Obispo County has been drafted and
comments were due to San Luis Obispo County Environmental Health on January 31,
2004. The City, and others, submitted their comments and no other activities have
occurred since that time. As discussed previously, there is no plan to more forward with
a permanent ordinance.
The permanent ordinance is based on the federal 40 CRF 503 regulations, the State of
California's General Discharge Order and recommendations from the San Luis Obispo
County biosolids task force (working group). This working group met 20 times over 20
months in 2000 and 2001 and prepared six primary recommendations for the San Luis
Obispo County Board of Supervisors regarding oversight, management and disposition of
land application of biosolids in San Luis Obispo County. The working group's
recommendations have been presented to other County advisory bodies in spring of 2002,
and were later presented to the San Luis Obispo County Board of Supervisors.
PATHOGEN REDUCTION
The City is using altemative 2 140 CFR 503.32(bX3)1, anaerobic digestion, for class B
sludge. The average annual temperatures and detention times during the reporting period
for the digesters was 32.1 C for 58.9 days at 17755.3 gpd feed. Flows vary between
14,339 gpd to 20,241 gpd average monthly flow. Sludge flows and temperature are
measured and recorded daily. At present digester #1 has a average detention time of 29.6
days @29.7 C, digester #2 is 16.6 days @34.6 C and digester #3, has a detention time of
12.7 days, unheated, but maintains digester's #2's temperature. These detentions times

VECTOR ATTRACTION REDUCTION
The City is using alternative I [40 CFR 503.33(bX1)], 38% Volatile Solids Reduction
(VSR) for vector attraction reduction. VSRs are tested almost weekly resulting in an
annual average of 64.4% VSR. Total VSRs ranged from 69.6oh to 24,4o/o. Two of the
samples were lower then the 38% target value. The target value for operation of the
digeiters is to achieve at least 38% VSR 100% of the time. Attachment C shows the
results of the WRF's VSR sampling.
All VSR analytical work is handled at the WRF laboratory using EPA approved methods
and following standard methods for sampling and testing. Raw sludge, flows between
the digesters and total (final) VSRs are analyzed every week'

difficult to obtain. FGL policy is to analyze all samples requiring pH on the same day of receipt at the
laboratory. If this presents any problem please call. All samples arrived on ice. All samples were
checked for pH if acid or base preservation is required (except for VOAs). For details of sample receipt
information, please see the attached Chain of Custody and Condition Upon Receipt Form.

Definition
CCV : Continuing Calibration Verification - Analyzed to verify the instrument calibration is within criteria.
Blank : Method Blank - Prepared to verify that the preparation process is not contributing contamination to the samples.
LCS : Laboratory Control Standard/Sample - Prepared to verify that the preparation process is not affecting analyte recovery.
MS : Matrix Spikes - A random sample is spiked with a known amount of analyte. The recoveries are an indication of how that sample
matrix affects analyte recovery.
MSD : Matrix Spike Duplicate of MS/MSD pair - A random sample duplicate is spiked with a known amount of analyted. The recoveries
are an indication of how that sample matrix affects analyte recovery.
MSRPD : MS/MSD Relative Percent Difference (RPD) - The MS relative percent difference is an indication of precision for the preparation
and analysis.
ND : Non-detect - Result was below the DQO listed for the analyte.
DQO : Data Quality Objective - This is the criteria against which the quality control data is compared.
Explanation

The City of San Luis Obispo operates a Water Reclamation Facility (WRF) that serves
the entire City, California State Polytechnic University and the County airport. This
represents a service population of over 40,000 and an average annual flow of 4.5 MGD.
The advanced tertiary facility includes: bar screens, aerated grit removal, primary
clarification, biofiltration, secondary clarification, activated sludge, final clarification,
dissolved air flotation thickening, filtration, cooling, flow equalization, disinfection and
dechlorination. The WRF discharges to San Luis Obispo Creek, an intermittent
freshwater stream. The City also administers an approved pretreatment program that has
4 permitted significant industries and 296 smaller permitted facilities. These facilities
include but are not limited to: restaurants, photoprocessers, automotive repair, dry
cleaners and hospitals. Attachment A includes a location map and schematic flow
diagram. Please note that the flow diagram does not include the belt press or filtration.
All sludge is digested anaerobically using three digesters arranged in a series. Digesters
#1 and #2 are heated and mixed while #3 functions more as a holding tank. During the
drier parts of the year the sludge is placed in drying beds, dried and stockpiled to await
shipment for compost. A belt filter press is used for the remainder of the year. The belt
filter press produces cake that is approximately 14-16% solids; this is also stockpiled
before shipment for compost.
Internal review of the 503 regulations, the City’s National Pollutant Discharge
Elimination System (NPDES) permit Monitoring and Reporting Program (M&RP) and
the recent reminder notification form EPA, it was determined that the City was not
required to continue sampling for pollutants on a bi-monthly basis because the City has
been using a composter that mixes the biolsolids with other agencies. Per the 503
regulations the frequency of monitoring applies to the composter, not the generator and
the City is required to sample as often as its NPDES permit and its agreement with the
composter stipulates. The City has adjusted its sampling schedule for pollutants and is
working closely with its composter, Engel and Gray Inc., to ensure compliance and
adequate sampling for the program.
The City’s biosolids are mixed with biosolids from other agencies and green waste
materials, placed in open windrows that are mechanically aerated and turned periodically.
Windrows are monitored daily for temperature and moisture until proper composting and
pathogenic destruction has been achieved, per the 40 CFR 503 regulations. City staff
performed an inspection of the facility in 2005 and found it to be a well managed and
compliant facility using industry standard methods for monitoring and managing their
composting operations. Finished compost is then sold to agricultural, horticultural and/or
landscape operations, some has been sold back to the City as a soil amendment. Engel
and Gray Inc. are a permitted facility that operates in Northern Santa Barbara County.
A capital project to drain, clean and inspect Digester #1 is slated to be completed during
the 2010-11 budget year. Digester #1 was last cleaned, inspected and repaired in July
2002.

The City has completed its energy project that utilizes digester gas to generate electricity
and provide heat for the digesters. The project provides significant energy savings for the
City’s WRF while offering an efficient and effective heating source for the digesters.
Back-up systems guarantee adequate heating and mixing at all times. Since operating the
system, the City has found it to be more efficient at heating the digesters than using the
boiler.
As previously reported, San Luis Obispo County Environmental Health has developed an
interim biosolids ordinance that prohibits land application of biosolids, except for
amounts that have been historically applied in the County, until the development and
adoption of a permanent ordinance. The interim ordinance offers some County control
over biosolids projects prior to development and adoption of a permanent ordinance. The
interim ordinance was first heard by the San Luis Obispo County Board of Supervisors in
November of 2003 and had its second hearing in February 2004 and was adopted in
March 2004. Because of County staff workload issues and no imminent need for a
permanent ordinance, the interim ordnance, which expired in summer of 2006, was
renewed for a 5 year period as a place holder until adequate County staff resources
become available and/or a need for a permanent ordinance is recognized.
To date the interim ordinance is still in place. San Luis Obispo County is looking at
performing an EIR for a full time ordinance and is working closely with the City of San
Luis Obispo and other local municipalities.
The permanent ordinance will be based on the federal 40 CRF 503 regulations, the State
of California’s General Discharge Order and recommendations from the San Luis Obispo
County biosolids task force (working group). This working group met 20 times over 20
months in 2000 and 2001 and prepared six primary recommendations for the San Luis
Obispo County Board of Supervisors regarding oversight, management and disposition of
land application of biosolids in San Luis Obispo County. The working group’s
recommendations have been presented to other County advisory bodies in spring of 2002,
and were later presented to the San Luis Obispo County Board of Supervisors.
PATHOGEN REDUCTION
The City is using alternative 2 [40 CFR 503.32(b)(3)], anaerobic digestion, for class B
sludge. The average annual temperatures and detention times during the reporting period
for the digesters was 31.0 C for 57.5 days at 18,188.8 gpd feed. Flows vary between
15,578 gpd to 21,237 gpd average monthly flow. Sludge flows and temperature are
measured and recorded daily. At present digester #1 has a average detention time of 28.9
days @ 28.7 C, digester #2 is 16.2 days @ 33.4 C and digester #3, has a detention time of
12.4 days, unheated, but maintains digester's #2’s temperature. These detentions times
and temperatures ensure adequate pathogen reduction. Attachment B shows monthly
averages for digester temperatures, flows and detention times.

VECTOR ATTRACTION REDUCTION
The City is using alternative 1 [40 CFR 503.33(b)(1)], 38% Volatile Solids Reduction
(VSR) for vector attraction reduction. VSRs are tested almost weekly resulting in an
annual average of 63.8% VSR. Total VSRs ranged from 71.5% to 37.7%. Only one of
the samples were lower then the 38% target value. The target value for operation of the
digesters is to achieve at least 38% VSR 100% of the time. Attachment C shows the
results of the WRF's VSR sampling.
All VSR analytical work is handled at the WRF laboratory using EPA approved methods
and following standard methods for sampling and testing. Raw sludge, flows between
the digesters and total (final) VSRs are analyzed every week.

City of San Luis Obispo -2009 Annual Biosolids Report.
February 12,2009
The City of San Luis Obispo operates a Water Reclamation Facility (WRF) that serves
the entire City, California State Polytechnic University and the County airport. This
represents a service population of over 40,000 and an average annual flow of 4.5 MGD.
The advanced tertiary facility includes: bar screens, aerated grit removal, primary
clarification, biofiltration, secondary clarification, activated sludge, final clarification,
dissolved air flotation thickening, filtration, cooling, flow equalization, disinfection and
dechlorination. The WRF discharges to San Luis Obispo Creek, an intermittent·
freshwater stream. The City also administers an approved pretreatment program that has
4 permitted significant industries and 296 smaller permitted facilities. These facilities
include but are not limited to: restaurants, photoprocessers, automotive repair, dry
cleaners and hospitals. Attachment A includes a location map and schematic flow
diagram. Please note that the flow diagram does not include the belt press or filtration.
All sludge is digested anaerobically using three digesters arranged in a series. Digesters
#1 and #2 are heated and mixed while #3 functions more as a holding tank. During the
drier parts of the year the sludge is placed in drying beds, dried and stockpiled to await
shipment for compost. A belt filter press is used for the remainder of the year. The belt
filter press produces cake that is approximately 14-16% solids; this is also stockpiled
before shipment for compost.
Internal review of the 503 regulations, the City's National Pollutant Discharge
Elimination System (NPDES) permit Monitoring and Reporting Program (M&RP) and
the recent reminder notification form EPA, it was determined that the City was not
required to continue sampling for pollutants on a bi-monthly basis because the City has
been using a composter that mixes the biolsolids with other agencies. Per the 503
regulations the frequency of monitoring applies to the composter, not the generator and
the City is required to sample as often as its NPDES permit and its agreement with the
composter stipulates. The City has adjusted its sampling schedule for pollutants and is
working closely with itscomposter, Engel and Gray Inc., to ensure compliance and
adequate sampling for the program.
The City's biosolids are mixed with biosolids from other agencies and green waste
materials, placed in open windrows that are mechanically aerated and turned periodically.
Windrows are monitored daily for temperature and moisture until proper composting and
pathogenic destruction has been achieved, per the 40 CFR 503 regulations. City staff
performed an inspection of the facility in 2005 and found it to be a well managed and
compliant facility using industry standard methods for monitoring and managing their
composting operations. Finished compost is then sold to agricultural, horticultural and/or
landscape operations, some has been sold back to the City as a soil amendment. Engel
and Gray Inc. are a permitted facility that operates in Northern Santa Barbara County.
A capital project to drain, clean and inspect Digester #1 is slated to be completed during
the 2010-11 budget year. Digester #1 was last cleaned, inspected and repaired in July
2002.

Definition
CCV : Continuing Calibration Verification - Analyzed to verify the instrument calibration is within criteria.
Blank : Method Blank - Prepared to verify that the preparation process is not contributing contamination to the samples.
LCS : Laboratory Control Standard/Sample - Prepared to verify that the preparation process is not affecting analyte recovery.
MS : Matrix Spikes - A random sample is spiked with a known amount of analyte. The recoveries are an indication of how that sample
matrix affects analyte recovery.
MSD : Matrix Spike Duplicate of MS/MSD pair - A random sample duplicate is spiked with a known amount of analyted. The recoveries
are an indication of how that sample matrix affects analyte recovery.
MSRPD : MS/MSD Relative Percent Difference (RPD) - The MS relative percent difference is an indication of precision for the preparation
and analysis.
ND : Non-detect - Result was below the DQO listed for the analyte.
DQO : Data Quality Objective - This is the criteria against which the quality control data is compared.
Explanation
325 : LCS not within Acceptance Range (AR). Data could not be confirmed by reanalysis. Use results with discretion.
360 : CCV above Acceptance Range (AR). Samples which were non detect for this analyte were accepted.
435 : Sample matrix may be affecting this analyte. Data was accepted based on the LCS or CCV recovery.
560 : Surrogate percent recoveries not within the Acceptance Range (AR) due to suspected matrix interferences.

City of San Luis Obispo -2010 Annual Biosolids Report.
February 1,2010
T1).e City of San Luis Obispo operates a Water Reclamation Facility (WRF) that serves
the entire City, California State Polytechnic University and the County airport. This
represents a service population of over 40,000 and an average annual flow of 4.5 MGD.
The advanced tertiary facility includes: bar screens, aerated grit removal, primary
clarification, biofiltration, secondary clarification, activated sludge, final clarification,
dissolved air flotation thickening, filtration, cooling, flow equalization, disinfection and
dechlorination. The WRF discharges to San Luis Obispo Creek, an intermittent
freshwater stream. The City also administers an approved pretreatment program that has
4 permitted significant industries and 296 smaller permitted facilities. These facilities
include but are not limited to: restaurants, photoprocessers; automotive repair, dry
cleaners and hospitals. Attachment A includes a location map and schematic flow
diagram. Please note that the flow diagram does not include the belt press or filtration.
All sludge is digested anaerobically using three digesters arranged in a series. Digesters
#1 and #2 are heated and mixed while #3 functions more as a holding tank. During the
drier parts of the year the sludge is placed in drying beds, dried and stockpiled to await
shipment for compost. A belt filter press is used for the remainder of the year. The belt
filter press produces cake that is approximately 14-16% solids; this is also stockpiled
before shipment for compost.
Internal review of the 503 regulations, the City's National Pollutant Discharge
Elimination System (NPDES) permit Monitoring and Reporting Program (M&RP) and
the recent reminder notification form EPA, it was determined that the City was not
required to continue sampling for pollutants on a bi-monthly basis because the City has
been using a composter that mixes the bioi solids with other agencies. Per the 503
regulations the frequency of monitoring applies to the composter, not the generator and
the City is required to sample as often as its NPDES permit and its agreement with the
composter stipulates. The City has adjusted its sampling schedule for pollutants and is
working closely with its composter, Engel and Gray Inc., to ensure compliance and
adequate sampling for the program.
The City's biosolids are mixed with biosolids from other agencies and green waste
materials, placed in open windrows that are mechanically aerated and turned periodically.
Windrows are monitored daily for temperature and moisture until proper compo sting and
pathogenic destruction has been achieved, per the 40 CFR 503 regulations. City staff
performed an inspection of the facility in 2005 and found it to be a well managed and
compliant facility using industry standard methods for monitoring and managing their
composting operations. Finished compost is then sold to agricultural, horticultural and/or
landscape operations, some has been sold back to the City as a soil amendment. Engel
and Gray Inc. are a permitted facility that operates in Northern Santa Barbara County.
A capital project to drain, clean and inspect Digester #1 is slated to be completed during
the 2011-12 budget year. Digester #1 was last cleaned, inspected and repaired in July
2002.

City of San Luis Obispo -2010 Annual Biosolids Report.
February 1,2010
The City is currently using a natural gas fired boiler to provide heat for the digesters. The
energy project, or cogeneration system, that was in place to utilize digester gas to
generate electricity and provide heat for the digesters is currently offline due to siloxane
removal capabilities and is being redesigned for future use. The project provided
significant energy savings for the City's WRF while offering an efficient and effective
heating source for the digesters. The City has found the cogeneration system to be more
efficient at heating the digesters than using the boiler. Because of this, the City expects to
have a redesigned, upgraded cogeneration system back online by 2012.
As previously reported, San Luis Obispo County Environmental Health has developed an
interim biosolids ordinance that prohibits land application of biosolids, except for
amounts that have been historically applied in the County, until the development and
adoption of a permanent ordinance. The interim ordinance offers some County control
over biosolids projects prior to development and adoption of a permanent ordinance. The
interim ordinance was first heard by the San Luis Obispo County Board of Supervisors in
November of 2003 and had its second hearing in February 2004 and was adopted in
March 2004. In September of 2004, the Board of Supervisors adopted the interim
biosolids ordinance that limited the land application of biosolids to amounts that were
historically applied in the county. This interim ordinance was adopted as a placeholder
until a permanent ordinance could be developed and approved. In April 2009 the Board
of Supervisors decided to defer the permanent ordinance after it was determined the
environmental review would cost $200,000 and on February 23, 2010 the interim
ordinance was extended for four years. County staff has indicated they are planning to
have a permanent ordinance adopted by late 2012 or early 2013.
To date the interim ordinance is still in place. San Luis Obispo County is looking at
performing an EIR for a full time ordinance and is working closely with the City of San
Luis Obispo and other local municipalities.
The permanent ordinance will be based on the federal 40 CRF 503 regulations, the State
of California's General Discharge Order and recommendations from the San Luis Obispo
County biosolids task force (working group). This working group met 20 times over 20
months in 2000 and 2001 and prepared six primary recommendations for the San Luis
Obispo County Board of Supervisors regarding oversight, management and disposition of
land application of biosolids in San Luis Obispo County. The working group's
recommendations have been presented to other County advisory bodies in spring of 2002,
and were later presented to the San Luis Obispo County Board of Supervisors.
PATHOGEN REDUCTION
The City is using alternative 2 [40 CFR 503.32(b)(3)], anaerobic digestion, for class B
sludge. The average annual temperatures and detention times during the reporting period
for the digesters was 30.5 C for 55.1 days at 18,959.3 gpd feed. Flows vary between
13,782 gpd to 24,731 gpd average monthly flow. Sludge flows and temperature are
measured and recorded daily. At present digester#l has a average detention time of27.7
days @ 29.2 C, digester #2 is 15.6 days @ 31.8 C and digester #3, has a detention time of
11.9 days, unheated, but maintains digester's #2's temperature. These detentions times

and temperatures ensure adequate pathogen reduction. Attachment B shows monthly
averages for digester temperatures, flows and detention times.
"I certify, under penalty oflaw, that the pathogen requirements in 503.32(b)(3) have been
met. This determination has been made under my direction or supervision in accordance
with a system designed to assure that qualified personnel properly gather and evaluate the
information used to determine that the pathogen requirements have been met. I am aware
that there are significant penalties for false certification, including the possibility of fine
Signature:
or imprisonment."

VECTOR ATTRACTION REDUCTION
The City is using alternative 1 [40 CFR 503.33(b)(l)], 38% Volatile Solids Reduction
(VSR) for vector attraction reduction. VSRs are tested almost weekly resulting in an
annual average of 65.1 % VSR. Total VSRs ranged from 75.1 % to 23.0%. Only two of
the samples were lower than the 38% target value. The first of the two samples
mentioned was the result of a 4 day rain event that yielded 10"+ of rain, affecting the raw
VS number. Another VSR taken after the storm showed acceptable range results. The
second of the two samples resulted from another heavy rain event, again affecting the
raw VS number. Another VSR sample was taken the next day, which again showed
acceptable range results. The target value for operation of the digesters is to achieve at
least 38% VSR 100% of the time. Attachment C shows the results of the WRF's VSR
sampling.
All VSR analytical work is handled at the WRF laboratory using EPA approved methods
and following standard methods for sampling and testing. Raw sludge, flows between
the digesters and total (final) VSRs are analyzed every week.

The City of San Luis Obispo operates a Water Reclamation Facility (WRF) that serves
the entire City, California State Polytechnic University and the County airport. This
represents a service population of over 40,000 and an average annual flow of 4.5 MGD.
The advanced tertiary facility includes: bar screens, aerated grit removal, primary
clarification, biofiltration, secondary clarification, activated sludge, final clarification,
dissolved air flotation thickening, filtration, cooling, flow equalization, disinfection and
dechlorination. The WRF discharges to San Luis Obispo Creek, an intermittent
freshwater stream. The City also administers an approved pretreatment program that has
4 permitted significant industries and 296 smaller permitted facilities. These facilities
include but are not limited to: restaurants, photoprocessers, automotive repair, dry
cleaners and hospitals. Attachment A includes a location map and schematic flow
diagram. Please note that the flow diagram does not include the belt press or filtration.
All sludge is digested anaerobically using three digesters arranged in a series. Digesters
#1 and #2 are heated and mixed while #3 functions more as a holding tank. During the
drier parts of the year the sludge is placed in drying beds, dried and stockpiled to await
shipment for compost. A belt filter press is used for the remainder of the year. The belt
filter press produces cake that is approximately 14-16% solids; this is also stockpiled
before shipment for compost.
Internal review of the 503 regulations, the City’s National Pollutant Discharge
Elimination System (NPDES) permit Monitoring and Reporting Program (M&RP) and
the recent reminder notification form EPA, it was determined that the City was not
required to continue sampling for pollutants on a bi-monthly basis because the City has
been using a composter that mixes the biolsolids with other agencies. Per the 503
regulations the frequency of monitoring applies to the composter, not the generator and
the City is required to sample as often as its NPDES permit and its agreement with the
composter stipulates. The City has adjusted its sampling schedule for pollutants and is
working closely with its composter, Engel and Gray Inc., to ensure compliance and
adequate sampling for the program.
The City’s biosolids are mixed with biosolids from other agencies and green waste
materials, placed in open windrows that are mechanically aerated and turned periodically.
Windrows are monitored daily for temperature and moisture until proper composting and
pathogenic destruction has been achieved, per the 40 CFR 503 regulations. City staff
performed an inspection of the facility in 2005 and found it to be a well managed and
compliant facility using industry standard methods for monitoring and managing their
composting operations. Finished compost is then sold to agricultural, horticultural and/or
landscape operations, some has been sold back to the City as a soil amendment. Engel
and Gray Inc. are a permitted facility that operates in Northern Santa Barbara County.
A capital project to drain, clean and inspect Digester #1 is slated to be completed during
the 2011-12 budget year. Digester #1 was last cleaned, inspected and repaired in July
2002.

The City is currently using a natural gas fired boiler to provide heat for the digesters. The
energy project, or cogeneration system, that was in place to utilize digester gas to
generate electricity and provide heat for the digesters is currently offline due to siloxane
removal capabilities and is being redesigned for future use. The project provided
significant energy savings for the City’s WRF while offering an efficient and effective
heating source for the digesters. The City has found the cogeneration system to be more
efficient at heating the digesters than using the boiler. Because of this, the City expects to
have a redesigned, upgraded cogeneration system back online by 2012.
As previously reported, San Luis Obispo County Environmental Health has developed an
interim biosolids ordinance that prohibits land application of biosolids, except for
amounts that have been historically applied in the County, until the development and
adoption of a permanent ordinance. The interim ordinance offers some County control
over biosolids projects prior to development and adoption of a permanent ordinance. The
interim ordinance was first heard by the San Luis Obispo County Board of Supervisors in
November of 2003 and had its second hearing in February 2004 and was adopted in
March 2004. In September of 2004, the Board of Supervisors adopted the interim
biosolids ordinance that limited the land application of biosolids to amounts that were
historically applied in the county. This interim ordinance was adopted as a placeholder
until a permanent ordinance could be developed and approved. In April 2009 the Board
of Supervisors decided to defer the permanent ordinance after it was determined the
environmental review would cost $200,000 and on February 23, 2010 the interim
ordinance was extended for four years. County staff has indicated they are planning to
have a permanent ordinance adopted by late 2012 or early 2013.
To date the interim ordinance is still in place. San Luis Obispo County is looking at
performing an EIR for a full time ordinance and is working closely with the City of San
Luis Obispo and other local municipalities.
The permanent ordinance will be based on the federal 40 CRF 503 regulations, the State
of California’s General Discharge Order and recommendations from the San Luis Obispo
County biosolids task force (working group). This working group met 20 times over 20
months in 2000 and 2001 and prepared six primary recommendations for the San Luis
Obispo County Board of Supervisors regarding oversight, management and disposition of
land application of biosolids in San Luis Obispo County. The working group’s
recommendations have been presented to other County advisory bodies in spring of 2002,
and were later presented to the San Luis Obispo County Board of Supervisors.
PATHOGEN REDUCTION
The City is using alternative 2 [40 CFR 503.32(b)(3)], anaerobic digestion, for class B
sludge. The average annual temperatures and detention times during the reporting period
for the digesters was 30.5 C for 55.1 days at 18,959.3 gpd feed. Flows vary between
13,782 gpd to 24,731 gpd average monthly flow. Sludge flows and temperature are
measured and recorded daily. At present digester #1 has a average detention time of 27.7
days @ 29.2 C, digester #2 is 15.6 days @ 31.8 C and digester #3, has a detention time of
11.9 days, unheated, but maintains digester's #2’s temperature. These detentions times

and temperatures ensure adequate pathogen reduction. Attachment B shows monthly
averages for digester temperatures, flows and detention times.
“I certify, under penalty of law, that the pathogen requirements in 503.32(b)(3) have been
met. This determination has been made under my direction or supervision in accordance
with a system designed to assure that qualified personnel properly gather and evaluate the
information used to determine that the pathogen requirements have been met. I am aware
that there are significant penalties for false certification, including the possibility of fine
or imprisonment."

VECTOR ATTRACTION REDUCTION
The City is using alternative 1 [40 CFR 503.33(b)(1)], 38% Volatile Solids Reduction
(VSR) for vector attraction reduction. VSRs are tested almost weekly resulting in an
annual average of 65.1% VSR. Total VSRs ranged from 75.1% to 23.0%. Only two of
the samples were lower than the 38% target value. The first of the two samples
mentioned was the result of a 4 day rain event that yielded 10”+ of rain, affecting the raw
VS number. Another VSR taken after the storm showed acceptable range results. The
second of the two samples resulted from another heavy rain event, again affecting the
raw VS number. Another VSR sample was taken the next day, which again showed
acceptable range results. The target value for operation of the digesters is to achieve at
least 38% VSR 100% of the time. Attachment C shows the results of the WRF's VSR
sampling.
All VSR analytical work is handled at the WRF laboratory using EPA approved methods
and following standard methods for sampling and testing. Raw sludge, flows between
the digesters and total (final) VSRs are analyzed every week.
"I certify, under penalty of law, that the vector attraction requirements in 503.33 have
been met. This determination has been made under my direction or supervision in
accordance with a system designed to assure that qualified personnel properly gather and
evaluate the information used to determine that the vector attraction requirements have
been met. I am aware that there are significant penalties for false certification, including
the possibility of fine or imprisonment”

QC Parameter Definitions
QC Batch: The QC batch consists of a set of up to 20 field samples that behave similarly (i.e., same matrix)
and are processed using the same procedures, reagents, and standards at the same time.
Method Blank: An analytical control consisting of all reagents, which may include internal standards and
surrogates, and is carried through the entire analytical procedure. The method blank is used to define the level
of laboratory background contamination.
Laboratory Control Sample and Laboratory Control Sample Duplicate (LCS/LCSD): An aliquot
of blank matrix spiked with known amounts of representative target analytes. The LCS (and LCSD as
required) is carried through the entire analytical process and is used to monitor the accuracy of the analytical
process independent of potential matrix effects. If an LCSD is performed, it may also be used to evaluate the
precision of the process.
Duplicate Sample (DU): Different aliquots of the same sample are analyzed to evaluate the precision of an
analysis.
Surrogates: Organic compounds not expected to be detected in field samples, which behave similarly to
target analytes. These are added to every sample within a batch at a known concentration to determine the
efficiency of the sample preparation and analytical process.
Matrix Spike and Matrix Spike Duplicate (MS/MSD): An MS is an aliquot of a matrix fortified with
known quantities of specific compounds and subjected to an entire analytical procedure in order to indicate the
appropriateness of the method for a particular matrix. The percent recovery for the respective compound(s) is
then calculated. The MSD is a second aliquot of the same matrix as the matrix spike, also spiked, in order to
determine the precision of the method.
Isotope Dilution: For isotope dilution methods, isotopically labeled analogs (internal standards) of the native
target analytes are spiked into the sample at time of extraction. These internal standards are used for
quantitation, and monitor and correct for matrix effects. Since matrix effects on method performance can be
judged by the recovery of these analogs, there is little added benefit of performing MS/MSD for these methods.
MS/MSD are only performed for client or QAPP requirements.
Control Limits: The reported control limits are either based on laboratory historical data, method
requirements, or project data quality objectives. The control limits represent the estimated uncertainty of the
test results.

The City of San Luis Obispo operates a Water Reclamation Facility (WRF) that serves
the entire City, California State Polytechnic University and the County airport. This
represents a service population of over 40,000 and an average annual flow of 4.5 MGD.
The advanced tertiary facility includes: bar screens, aerated grit removal, primary
clarification, biofiltration, secondary clarification, activated sludge, final clarification,
dissolved air flotation thickening, anaerobic digestions, biosolids dewatering, tertiary
filtration, cooling, flow equalization, reclaimed/recycled wastewater treatment,
disinfection and dechlorination. The WRF discharges to San Luis Obispo Creek, an
intermittent freshwater stream. The WRF has a recycled water system that delivers
reclaimed water to parks, golf courses and ornamental landscaping throughout the City.
The City also administers an approved pretreatment program that has 4 permitted
significant industries and 296 smaller permitted facilities. These facilities include but are
not limited to: restaurants, photoprocessers, automotive repair, dry cleaners and hospitals.
Attachment A includes a location map and schematic flow diagram. Please note that the
flow diagram does not include the belt press or filtration.
All sludge is digested anaerobically using three digesters arranged in a series. Digesters
#1 and #2 are heated and mixed while #3 functions more as a holding tank. During the
drier parts of the year the sludge is placed in drying beds, dried and stockpiled to await
shipment for compost. A belt filter press is used for the remainder of the year. The belt
filter press produces cake that is approximately 14-16% solids; this is also stockpiled
before shipment for compost.
Internal review of the 503 regulations, the City’s National Pollutant Discharge
Elimination System (NPDES) permit Monitoring and Reporting Program (M&RP) and
the recent reminder notification form EPA, it was determined that the City was not
required to continue sampling for pollutants on a bi-monthly basis because the City has
been using a composter that mixes the biolsolids with other agencies. Per the 503
regulations the frequency of monitoring applies to the composter, not the generator and
the City is required to sample as often as its NPDES permit and its agreement with the
composter stipulates. The City has adjusted its sampling schedule for pollutants and is
working closely with its composter, Engel and Gray Inc., to ensure compliance and
adequate sampling for the program.
The City’s biosolids are mixed with biosolids from other agencies and green waste
materials, placed in open windrows that are mechanically aerated and turned periodically.
Windrows are monitored daily for temperature and moisture until proper composting and
pathogenic destruction has been achieved, per the 40 CFR 503 regulations. City staff
performed an inspection of the facility in 2005 and found it to be a well managed and
compliant facility using industry standard methods for monitoring and managing their
composting operations. Finished compost is then sold to agricultural, horticultural and/or
landscape operations, some has been sold back to the City as a soil amendment. Engel
and Gray Inc. are a permitted facility that operates in Northern Santa Barbara County.
Digester #1 was taken offline in July of 2011 and was cleaned, inspected and repaired. It
was returned to service in October of 2011. Digester #3 was taken offline in November of
2011 and was cleaned and inspected. It was returned to service in December of 2011.

The City is currently using a natural gas fired boiler to provide heat for the digesters. The
energy project, or cogeneration system, that was in place to utilize digester gas to
generate electricity and provide heat for the digesters is currently offline due to siloxane
removal capabilities and is being redesigned for future use. The project provided
significant energy savings for the City’s WRF while offering an efficient and effective
heating source for the digesters. The City has found the cogeneration system to be more
efficient at heating the digesters than using the boiler. Because of this, the City expects to
have a redesigned, upgraded cogeneration system back online by 2013.
As previously reported, San Luis Obispo County Environmental Health has developed an
interim biosolids ordinance that prohibits land application of biosolids, except for
amounts that have been historically applied in the County, until the development and
adoption of a permanent ordinance. The interim ordinance offers some County control
over biosolids projects prior to development and adoption of a permanent ordinance. The
interim ordinance was first heard by the San Luis Obispo County Board of Supervisors in
November of 2003 and had its second hearing in February 2004 and was adopted in
March 2004. In September of 2004, the Board of Supervisors adopted the interim
biosolids ordinance that limited the land application of biosolids to amounts that were
historically applied in the county. This interim ordinance was adopted as a placeholder
until a permanent ordinance could be developed and approved. In April 2009 the Board
of Supervisors decided to defer the permanent ordinance after it was determined the
environmental review would cost $200,000 and on February 23, 2010 the interim
ordinance was extended for four years. County staff has indicated they are planning to
have a permanent ordinance adopted by late 2012 or early 2013.
To date the interim ordinance is still in place. San Luis Obispo County is looking at
performing an EIR for a full time ordinance and is working closely with the City of San
Luis Obispo and other local municipalities.
The permanent ordinance will be based on the federal 40 CRF 503 regulations, the State
of California’s General Discharge Order and recommendations from the San Luis Obispo
County biosolids task force (working group). This working group met 20 times over 20
months in 2000 and 2001 and prepared six primary recommendations for the San Luis
Obispo County Board of Supervisors regarding oversight, management and disposition of
land application of biosolids in San Luis Obispo County. The working group’s
recommendations have been presented to other County advisory bodies in spring of 2002,
and were later presented to the San Luis Obispo County Board of Supervisors.

PATHOGEN REDUCTION
The City is using alternative 2 [40 CFR 503.32(b)(3)], anaerobic digestion, for class B
sludge. The average annual temperatures and detention times during the reporting period
for the digesters was 31.1 C for 59.9 days at 17440.3 gpd feed. Flows vary between
13,790 gpd to 23,600 gpd average monthly flow. Sludge flows and temperature are
measured and recorded daily. At present digester #1 has a average detention time of 30.1
days @ 30.4 C, digester #2 is 16.9 days @ 31.9 C and digester #3, has a detention time of
12.9 days, unheated, but maintains digester's #2’s temperature. These detentions times
and temperatures ensure adequate pathogen reduction. Attachment B shows monthly
averages for digester temperatures, flows and detention times.
“I certify, under penalty of law, that the pathogen requirements in 503.32(b)(3) have been
met. This determination has been made under my direction or supervision in accordance
with a system designed to assure that qualified personnel properly gather and evaluate the
information used to determine that the pathogen requirements have been met. I am aware
that there are significant penalties for false certification, including the possibility of fine
or imprisonment."

VECTOR ATTRACTION REDUCTION
The City is using alternative 1 [40 CFR 503.33(b)(1)], 38% Volatile Solids Reduction
(VSR) for vector attraction reduction. VSRs are tested almost weekly resulting in an
annual average of 68.2% VSR. Total VSRs ranged from 81.4% to 45.3%. None of the
samples were lower than the 38% target value. Attachment C shows the results of the
WRF's VSR sampling.
There was no sampling done in October due to the filling of Digester #1 after it had been
taken offline for cleaning, inspection and maintenance. Digester #1 was filled to 80%
capacity with biosolids from digesters #2 and #3, resulting in no effluent flows from
those units during that time.
All VSR analytical work is handled at the WRF laboratory using EPA approved methods
and following standard methods for sampling and testing. Raw sludge, flows between
the digesters and total (final) VSRs are analyzed every week.
"I certify, under penalty of law, that the vector attraction requirements in 503.33 have
been met. This determination has been made under my direction or supervision in
accordance with a system designed to assure that qualified personnel properly gather and
evaluate the information used to determine that the vector attraction requirements have
been met. I am aware that there are significant penalties for false certification, including
the possibility of fine or imprisonment”

City of San Luis Obispo -2011 Annual Biosolids Report.
February 1,2012
The City of San Luis Obispo operates a Water Reclamation Facility (WRF) that serves
the entire City, California State Polytechnic University and the County airport. This
represents a service population of over 40,000 and an average annual flow of 4.5 MGD.
The advanced tertiary facility includes: bar screens, aerated grit removal, primary
clarification, biofiltration, secondary clarification, activated sludge, final clarification,
dissolved air flotation thickening, anaerobic digestions, biosolids dewatering, tertiary
filtration, cooling, flow equalization, reclaimed/recycled wastewater treatment,
disinfection and dechlorination. The WRF discharges to San Luis Obispo Creek, an
intennittent freshwater stream. The WRF has a recycled water system that delivers
reclaimed water to parks, golf courses and ornamental landscaping throughout the City.
The City also administers an approved pretreatment program that has 4 pennitted
significant industries and 296 smaller pennitted facilities. These facilities include but are
not limited to: restaurants, photoprocessers, automotive repair, dry cleaners and hospitals.
Attachment A includes a location map and schematic flow diagram. Please note that the
flow diagram does not include the belt press or filtration.
All sludge is digested anaerobically using three digesters arranged in a series. Digesters
#1 and #2 are heated and mixed while #3 functions more as a holding tank. During the
drier parts of the year the sludge is placed in drying beds, dried and stockpiled to await
shipment for compost. A belt filter press is used for the remainder of the year. The belt
filter press produces cake that is approximately 14-16% solids; this is also stockpiled
before shipment for compost.
Internal review of the 503 regulations, the City's National Pollutant Discharge
Elimination System (NPDES) pennit Monitoring and Reporting Program (M&RP) and
the recent reminder notification fonn EPA, it was detennined that the City was not
required to continue sampling for pollutants on a bi-monthly basis because the City has
been using a composter that mixes the biolsolids with other agencies. Per the 503
regulations the frequency of monitoring applies to the composter, not the generator and
the City is required to sample as often as its NPDES pennit and its agreement with the
composter stipulates. The City has adjusted its sampling schedule for pollutants and is
working closely with its composter, Engel and Gray Inc., to ensure compliance and
adequate sampling for the program.
The City's biosolids are mixed with biosolids from other agencies and green waste
materials, placed in open windrows that are mechanically aerated and turned periodically.
Windrows are monitored daily for temperature and moisture until proper compo sting and
pathogenic destruction has been achieved, per the 40 CFR 503 regulations. City staff
perfonned an inspection of the facility in 2005 and found it to be a well managed and
compliant facility using industry standard methods for monitoring and managing their
composting operations. Finished compost is then sold to agricultural, horticultural and/or
landscape operations, some has been sold back to the City as a soil amendment. Engel
and Gray Inc. are a pennitted facility that operates in Northern Santa Barbara County.
Digester #1 was taken offline in July of 2011 and was cleaned, inspected and repaired. It
was returned to service in October of 2011. Digester #3 was taken offline in November of
2011 and was cleaned and inspected. It was returned to service in December of 20 11.

City of San Luis Obispo -2011 Annual Biosolids Report.
February 1,2012
The City is currently using a natural gas fired boiler to provide heat for the digesters. The
energy project, or cogeneration system, that was in place to utilize digester gas to
generate electricity and provide heat for the digesters is currently offline due to siloxane
removal capabilities and is being redesigned for future use. The project provided
significant energy savings for the City's WRF while offering an efficient and effective
heating source for the digesters. The City has found the cogeneration system to be more
efficient at heating the digesters than using the boiler. Because of this, the City expects to
have a redesigned, upgraded cogeneration system back online by 2013.
As previously reported, San Luis Obispo County Environmental Health has developed an
interim biosolids ordinance that prohibits land application of biosolids, except for
amounts that have been historically applied in the County, until the development and
adoption of a permanent ordinance. The interim ordinance offers some County control
over biosolids projects prior to development and adoption of a permanent ordinance. The
interim ordinance was first heard by the San Luis Obispo County Board of Supervisors in
November of 2003 and had its second hearing in February 2004 and was adopted in
March 2004. In September of 2004, the Board of Supervisors adopted the interim
biosolids ordinance that limited the land application of biosolids to amounts that were
historically applied in the county. This interim ordinance was adopted as a placeholder
until a permanent ordinance could be developed and approved. In April 2009 the Board
of Supervisors decided to defer the permanent ordinance after it was determined the
environmental review would cost $200,000 and on February 23, 2010 the interim
ordinance was extended for four years. County staff has indicated they are planning to
have a permanent ordinance adopted by late 2012 or early 2013.
To date the interim ordinance is still in place. San Luis Obispo County is looking at
performing an EIR for a full time ordinance and is working closely with the City of San
Luis Obispo and other local municipalities.
The permanent ordinance will be based on the federal 40 CRF 503 regulations, the State
of California's General Discharge Order and recommendations from the San Luis Obispo
County biosolids task force (working group). This working group met 20 times over 20
months in 2000 and 200 I and prepared six primary recommendations for the San Luis
Obispo County Board of Supervisors regarding oversight, management and disposition of
land application of biosolids in San Luis Obispo County. The working group's
recommendations have been presented to other County advisory bodies in spring of 2002,
and were later presented to the San Luis Obispo County Board of Supervisors.

PATHOGEN REDUCTION
The City is using alternative 2 [40 CFR 503.32(b)(3)], anaerobic digestion, for class B
sludge. The average annual temperatures and detention times during the reporting period
for the digesters was 31.1 C for 59.9 days at 17440.3 gpd feed. Flows vary between
13,790 gpd to 23,600 gpd average monthly flow. Sludge flows and temperature are
measured and recorded daily. At present digester #1 has a average detention time of 30.1
days @ 30.4 C, digester #2 is 16.9 days @ 31.9 C and digester #3, has a detention time of
12.9 days, unheated, but maintains digester's #2's temperature. These detentions times
and temperatures ensure adequate pathogen reduction. Attachment B shows monthly
averages for digester temperatures, flows and detention times.
"I certify, under penalty oflaw, that the pathogen requirements in 503.32(b)(3) have been
met. This determination has been made under my direction or supervision in accordance
with a system designed to assure that qualified personnel properly gather and evaluate the
information used to determine that the pathogen requirements have been met. I am aware
that there are significant penalties for false certification, including the possibility of fine
or imprisonment."

VECTOR ATTRACTION REDUCTION
The City is using alternative 1 [40 CFR 503.33(b)(I)], 38% Volatile Solids Reduction
(VSR) for vector attraction reduction. VSRs are tested almost weekly resulting in an
annual average of 68.2% VSR. Total VSRs ranged from 81.4% to 45.3%. None of the
samples were lower than the 38% target value. Attachment C shows the results of the
WRF's VSR sampling.
There was no sampling done in October due to the filling of Digester #1 after it had been
taken offline for cleaning, inspection and maintenance. Digester #1 was filled to 80%
capacity with biosolids from digesters #2 and #3, resulting in no effluent flows from
those units during that time.
All VSR analytical work is handled at the WRF laboratory using EPA approved methods
and following standard methods for sampling and testing. Raw sludge, flows between
the digesters and total (final) VSRs are analyzed every week.
"I certify, under penalty of law, that the vector attraction requirements in 503.33 have
been met. This determination has been made under my direction or supervision in
accordance with a system designed to assure that qualified personnel properly gather and
evaluate the information used to determine that the vector attraction requirements have
been met. I am aware that there are significant penalties for false certification, including
the possibility of fine or imprisonment"

FACILITY NARRATIVE:
The City of San Luis Obispo operates a Water Reclamation Facility (WRF) that serves
the entire City, California State Polytechnic University and the County airport. This
represents a service population of over 40,000 and an average annual flow of 4.5 MGD.
The advanced tertiary facility includes: bar screens, aerated grit removal, primary
clarification, biofiltration, secondary clarification, activated sludge, final clarification,
dissolved air flotation thickening, anaerobic digestions, biosolids dewatering, tertiary
filtration, cooling, flow equalization, reclaimed/recycled wastewater treatment,
disinfection and dechlorination. The WRF discharges to San Luis Obispo Creek, an
intermittent freshwater stream. The WRF has a recycled water system that delivers
reclaimed water to parks, golf courses and ornamental landscaping throughout the City.
The City also administers an approved pretreatment program that has 7 permitted
significant industries and 315 smaller permitted facilities. These facilities include but are
not limited to: restaurants, photoprocessers, automotive repair, dry cleaners and hospitals.
Attachment A includes a location map and schematic flow diagram. Please note that the
flow diagram does not include the belt press or filtration.
BIOSOLIDS NARRATIVE:
All sludge is digested anaerobically using three digesters arranged in a series. Digesters
#1 and #2 are heated and mixed while #3 functions more as a holding tank. During the
drier parts of the year the sludge is placed in drying beds, dried and stockpiled to await
shipment for compost. A belt filter press is used for the remainder of the year. The belt
filter press produces cake that is approximately 14-16% solids; this is also stockpiled
before shipment for compost.
Internal review of the 503 regulations, the City’s National Pollutant Discharge
Elimination System (NPDES) permit Monitoring and Reporting Program (M&RP) and
the recent reminder notification form EPA, it was determined that the City was not
required to continue sampling for pollutants on a bi-monthly basis because the City has
been using a composter that mixes the biosolids with other agencies. Per the 503
regulations the frequency of monitoring applies to the composter, not the generator and
the City is required to sample as often as its NPDES permit and its agreement with the
composter stipulates. The City has adjusted its sampling schedule for pollutants and is
working closely with its composter, Engel and Gray Inc., to ensure compliance and
adequate sampling for the program.
The City’s biosolids are mixed with biosolids from other agencies and green waste
materials, placed in open windrows that are mechanically aerated and turned periodically.
Windrows are monitored daily for temperature and moisture until proper composting and
pathogenic destruction has been achieved, per the 40 CFR 503 regulations. City staff
performed an inspection of the facility in 2012 and found it to be a well managed and
compliant facility using industry standard methods for monitoring and managing their
composting operations. Finished compost is then sold to agricultural, horticultural and/or
City of San Luis Obispo - 2012 Annual Biosolids Report.

landscape operations, some has been sold back to the City as a soil amendment. Engel
and Gray Inc. is a permitted facility that operates in Northern Santa Barbara County.
The City is currently using a natural gas fired boiler to provide heat for the digesters. The
energy project, or cogeneration system, that was in place to utilize digester gas to
generate electricity and provide heat for the digesters is currently offline due to siloxane
removal capabilities and is being redesigned for future use. The project provided
significant energy savings for the City’s WRF while offering an efficient and effective
heating source for the digesters. The City has found the cogeneration system to be more
efficient at heating the digesters than using the boiler. Because of this, the City expects to
have a redesigned, upgraded cogeneration system back online by 2014.
As previously reported, San Luis Obispo County Environmental Health has developed an
interim biosolids ordinance that prohibits land application of biosolids, except for
amounts that have been historically applied in the County, until the development and
adoption of a permanent ordinance. The interim ordinance offers some County control
over biosolids projects prior to development and adoption of a permanent ordinance.
On February 8, 2000, the Board directed the Public Health Department to convene a
public working group to consider options for managing the land application of biosolids.
This working group met in 2000 and 2001 and prepared six primary recommendations for
the San Luis Obispo County Board of Supervisors regarding oversight, management and
disposition of land application of biosolids in San Luis Obispo County. The Task Force
recommended creation of a local ordinance establishing more stringent requirements for
the quality of land applied biosolids, as well as local control and oversight of how, when
and where such material may be applied. The Task Force completed its
recommendations on October 26, 2001. Presentations were made to the Health
Commission on December 10, 2001, and the Planning Commission on December 13,
2001, and January 24, 2002.
On March 12, 2002, the Board directed the Public Health Department to draft a local
ordinance regulating the land application of biosolids based on the recommendations
contained in the Task Force report. In order to comply with Board direction, the Task
Force reconvened to draft an interim ordinance that would, among other things, limit the
acceptance or processing of new land application projects beyond historical amounts of
exceptional quality biosolids until a local ordinance is completed.
On March 12, 2003, the original interim ordinance was completed and sent to the
Environmental Division of the Planning Department for California Environmental
Quality Act (CEQA) review. The CEQA review process was completed on August 29,
2003, where it was determined that the ordinance could not have a significant adverse
effect on the environment and a Negative Declaration was issued.
The proposed interim ordinance was then introduced to the Board for approval in
February of 2004, and subsequently enacted on March 2, 2004.

was extended by the Board for 48 months until February 28, 2010, or until a permanent
ordinance could be developed.
The Board voted on April 21, 2009 to defer the proposed permanent ordinance
development process due to concerns regarding the estimated cost of environmental
review associated with the CEQA process. The cost of an environmental review was
estimated to be $200,000. As a result, the Board decided to amend the existing interim
ordinance for another 48 months or until a permanent ordinance is enacted.
On March 9, 2010 the Board approved Ordinance 3023: Moratorium on the Land
Application of Treated Sewage Sludge/Biosolids.
A permanent ordinance has not been enacted and the current interim ordinance will
expire on March 9, 2014.
The Board met on January 29, 2013 to consider three options for amending/replacing the
interim ordinance.
The recommended option was to extend the existing interim ordinance until March 2017.
The permanent ordinance will be based on the federal 40 CRF 503 regulations, the State
of California’s General Discharge Order and recommendations from the San Luis Obispo
County Treated Sewage Sludge/Biosolids Land Application Task Force.

PATHOGEN REDUCTION
The City is using alternative 2 [40 CFR 503.32(b)(3)], anaerobic digestion, for class B
sludge. The average annual temperatures and detention times during the reporting period
for the digesters was 34.6 C for 50.8 days at 20565.0 gpd feed. Flows vary between
17,679 gpd to 23,382 gpd average monthly flow. Sludge flows and temperature are
measured and recorded daily. At present digester #1 has a average detention time of 25.5
days @ 33.8 C, digester #2 is 14.3 days @ 35.4 C and digester #3, has a detention time of
10.9 days, unheated, but maintains digester's #2’s temperature. These detentions times
and temperatures ensure adequate pathogen reduction. Attachment B shows monthly
averages for digester temperatures, flows and detention times.
“I certify, under penalty of law, that the pathogen requirements in 503.32(b)(3) have been
met. This determination has been made under my direction or supervision in accordance
with a system designed to assure that qualified personnel properly gather and evaluate the
information used to determine that the pathogen requirements have been met. I am aware
that there are significant penalties for false certification, including the possibility of fine
or imprisonment."

VECTOR ATTRACTION REDUCTION
The City is using alternative 1 [40 CFR 503.33(b)(1)], 38% Volatile Solids Reduction
(VSR) for vector attraction reduction. VSRs are tested almost weekly resulting in an
annual average of 62.0% VSR. Total VSRs ranged from 71.0% to 27.8%. One of the
samples was lower than the 38% target value. This was due to a sampling error in which
the sample was taken as the bottom of the tank was being pumped, resulting in a non-
representative sample. Attachment C shows the results of the WRF's VSR sampling.
All VSR analytical work is handled at the WRF laboratory using EPA approved methods
and following standard methods for sampling and testing. Raw sludge, flows between
the digesters and total (final) VSRs are analyzed every week.
"I certify, under penalty of law, that the vector attraction requirements in 503.33 have
been met. This determination has been made under my direction or supervision in
accordance with a system designed to assure that qualified personnel properly gather and
evaluate the information used to determine that the vector attraction requirements have
been met. I am aware that there are significant penalties for false certification, including
the possibility of fine or imprisonment”

Definition
CCV : Continuing Calibration Verification - Analyzed to verify the instrument calibration is within criteria.
Blank : Method Blank - Prepared to verify that the preparation process is not contributing contamination to the samples.
LCS : Laboratory Control Standard/Sample - Prepared to verify that the preparation process is not affecting analyte recovery.
MS : Matrix Spikes - A random sample is spiked with a known amount of analyte. The recoveries are an indication of how that sample
matrix affects analyte recovery.
MSD : Matrix Spike Duplicate of MS/MSD pair - A random sample duplicate is spiked with a known amount of analyted. The recoveries
are an indication of how that sample matrix affects analyte recovery.
MSRPD : MS/MSD Relative Percent Difference (RPD) - The MS relative percent difference is an indication of precision for the preparation
and analysis.
ND : Non-detect - Result was below the DQO listed for the analyte.
DQO : Data Quality Objective - This is the criteria against which the quality control data is compared.
Explanation
310 : LCS above Acceptance Range (AR). Samples which were non detect for this analyte were accepted.
325 : LCS not within Acceptance Range (AR). Data could not be confirmed by reanalysis. Use results with discretion.
360 : CCV above Acceptance Range (AR). Samples which were non detect for this analyte were accepted.
435 : Sample matrix may be affecting this analyte. Data was accepted based on the LCS or CCV recovery.

Hi Pam,
This is to confirm that US EPA received the City of San Luis Obispo's biosolids report for 2012.
I had one question - is the 3441 metric tons that is reported as being generated on a wet weight basis, at
about 15% solids?
Thanks,

Dear Ms. Fondahl,
Thank you for the phone conversation yesterday. The 2011 guide was used to prepare this annual report.
The document states that if biosolids of a facility is not land applied, is not placed in a surface disposal
site or incinerated, then electronic submittal of the annual report is allowed. Since the City of San Luis
Obispo’s Water Reclamation Facility’s biosolids program meets this criteria, we are submitting the annual
report as stated.
We are requesting electronic delivery and read receipts for this submission as a substitute for a Certified
Mail Receipt.
Please feel free to contact myself or Howard Brewen, Facility Supervisor, if there are any questions
concerning this report.
Mr. Brewen’s contact information is: hbrewen@slocity.org phone: 805.781.7240
Regards,
