BAN F.ANCS&CO 2 CALIFORNIA October 28, 1947 City Clerk San Luis Obispo California Subject: Sewage Disposal Permit City of San Luis Obispo Dear Sir: Application of the City of San Luis Obispo, dated Au- gust 25, 1947, for permit to construct municipal sewage works en- largements comprising a final clarifier, an additional sludge digestion tank and sludge aeration tenks, and to dispose of an oxidized and chlorinated plant effluent on the city sewer farm by broad irrigation or by overflow to San Luis Obispo Creek, after not less than five days storage in effluent ponds, has been con- sidered by the State Department of Public Health. Analysis of the problem has been made on the basis of an snUneerin„ report submitted by the consulting sanitary engi- neer for the city, and on additional information obtained at a public hearing held in the City of San Luis Obispo on October 2, 1947. Findings of the State Depertlaent of Public Health in re- gard to the proposed project are as given in the following para- graphs: Population of the City of San Luis Obispo is estimated at 12,000. Ytis estimated that during the next 5 to 10 years this population may increase by 5,000, giving a total human pop- ulation of 17,000. Industrial wastes of the City of San Luis Obispo are all discharged to the domestic sewers. At the present time, the industrial wastes are chiefly from two creameries and from a slaughter house. The population equivalent is estimated at 8,000 persons, giving a present combined population equivalent of 20,000. City Clerk, San Luis Obispo - 2 - October 23, 1947 It is anticipated that during the next 5 to 10 years the industrial load may increase by an amount equivalent to 5,000 population and this, together with the estimated increase of 5,000 human popula- tion, would give a combined future load in 5 to 10 years of 30,000 population equivalent. The ultimate population used for design is 40,000. Domestic sewage flow, including industrial waste for the City of San Luis Obispo, has ranged from 1.25 to 1.75 m.g.d. For the immediate future load of 30,000 population equivalent, it is estimated that the sewage flan may be 3 m.g.d. and this quantity has been used in reviewing the hydraulic loadings of the proposed treatment plant. The ultimate load for design purposes is taken at 40,000 population with a flow of 4 m.g.d. Existing treatment of the combined domestic sewage and industrial waste includes primary clarification, primary stage biofiltration, secondary clarification and secondary stage biofil- tration, with two -stage sludge digestion. Improvements are under way at the plant to bring it up to the design capacity of 20,000 population, for which permit was granted August 22, 1946. The im- provements include comminutors, digester sludge gas collection and heating equipment and miscellaneous plant pipe work and appurte- nances for odor control. Subsequent to the granting of the 1946 permit, following complaints of neighborhood nuisance in the spring of 1947, a second chlorinator was purchased so that chlorination is now in duplicate. Proposed additional treatment facilities, for which per- mit has been requested, inc ude a new Yinal c arifier, a new sludge digestion tank and sludge aeration tanks operating in conjunction therewith, together with preehlorination facilities and preaera- tion with activated sludge for odor control. Plans have been made for the further addition of another biofilter unit to bring the capacity of the plant up to an ultimate population equivalent of 40,000. In the meantime, the consulting sanitary engineer for the city reports that in his opinion, since the new plant unite for which permit has been requested will give a longer detention peri- od in the final clarifier and the deleterious effects. of super- natant liquor will be well controlled, the plant can satisfactorily handle a population equivalent of 30,000 persons. Loadings of the proposed units are at variance with normally accepted design stand- ards. The higher loading on the filter unit will be partly compen- sateft for by longer detention period in the clarifier units. With careful operation, this plant may be expected to produce a well - oxidized effluent. The treatment plant site is adjacent to the present sew- age treatment plant units on the sewer farm approximately one mile south of the City of San Luis Obispo. The treatment plant units City Clerk, San Luis Obispo - 3 - October 23, are not well isolated, and Complaints of odor nuisance have fr quently occurred in the past few years. It is important that t sewage treatment works as enlarged be operated so as to minimiz neighborhood nuisance. Dis osal of effluent will be to the city sewer farm of about 35 scree th excess Hoar to effluent ponds having a oapacit equivalent to five days sewage flow. On the basis of past experi- ence, it is anticipated that during the dry season, sewage can be discharged to the land with no overflow to San Luis Obispo Creek. However, during the winter season, it is anticipated that efflu- ent will overflow to San Luis Obispo Creek and plans have been made for the effluent ponds to store the chlorinated, oxidized sewage for at least five days before discharge. The consulting sanitary engineer for the city agreed that it would be reasonable to require that no discharge be allowed to reach the Creek when the flow avail- able for dilution was less than an amount required to give a dilu- tion of 10 to 1. The quantity of water or sewage effluent that could be absorbed on the sewer farm has not been measured, and it is therefore difficult to predict how much sewage effluent might escape to San Luis Obispo Creek. However, if the sewage is treated as proposed to produce an oxidized effluent, and only the excess which cannot be absorbed on the farm is carried to effluent ponds, the resulting overflow to San Luis Obispo Creek should not be a nuisance or a menace to health. It is concluded thht the purposes of the Health and Safety Code with respect to the disposal of sewage can be served by the project as applied for and that the project is necessary. With the foregoing findings in mind, permit is hereby granted to the City of San Luis Obispo as applied for, said permit being subject to the following special provisions: (1) There shall be no noxious or offensive odor, gases or fumes of sewage origin in the air outside the immediate disposal area, such that they may constitute a public nuisance; (2) No condition or conditions resulting from the opera- tion of said sewage treatment plant and disposal shall exist or be permitted to exist which may constitute a hazard to the health of human beings or animals, or which may constitute a public nuisance un"Ier the laws of the State of California. Mosquito control mea- sures shall be carried out as necessary; (3) The use of sewage, sewage effluent or sludge for irrigating crops shall be in conformance with "Regulations on Use o: wwage for Irri;atiz)g Crops", Special Bulletin No. 59 of the State Department of Public Health; City Clerk, San Luis Obispo - 4 - October 28, 1947 (4) Overflax or discharge of sewage effluent to San Luis Obispo Creek shall be limited to the season of high stream flow and in no event shall sewage effluent be discharged to the oreek in a quantity greater than one -tenth of the quantity flowing in the oreek channel; (5) Disposal of sewage or sewage effluent shall be con- fined to areas covered by this permit, and shall be carried out in such a manner as not to create a nuisance or hazard to the public health; (6) No industry with wastes of significant strength or volume shall be connected to the domestic sewerage system unless prior approval is given by the Bureau of Sanitary Engineering of the State Department of Public Health; (7) Operating records of the treatment plant shall be maintained by the city indicating the sewage flow, the residual chlorine in the effluent, and such other data as may be required by the Bureau of Sanitary Engineering of the State Department of Public Health; (8) Final plans shall be submitted to the Bureau of Sanitary Engineering of the State Department of Public Health for approval in advance of construction; (9) Additional treatment works or improvements in oper- ation shall be provided when required by the State Department of Public Health. The permit herewith granted supersedes all previous sew- age treatment and disposal permits granted to the City of San Luis Obispo by the State Board of Public Health or by the State Depart- ment of Public Health.

Hertel May 22, 1947 The San Luis Obispo Sewage Treatment Plant providing for primary clarification, two -stage hiofiltretlon with recirculation, and final clarification with chlorination of the effluent was placed in operation August 1943 under permit granted by the Board of Public Health, Dec. 10, 1941. A new permit was issued August 22, 1946 grentirg certain additions to the plant which the 1941 permit allowed them to omit. This replaced the 1941 permit. On Dec. 12, 1946 the Aug. 22, 1946 permit was smanded and any outetanding permits other than the Aug. 22, 1946 permit were cancelled. This plant treats the sswnee of San Luis Obispo, including the indus- trial waste from two creameries,and that of the Calif. Polytechnic School and R'lteosky's Slaughter Rouse by contract arrangement. There are before us complaints elleglno the San Luis Obispo Sewage Treatment plant is overlorded end as a conseauence its operation is creative a public health menace and public health nuisance. A review of our files indicates frequent complaints and the observation of Dr. Beerg, S.L.O. County Health Officer, that the sewage treatment plant has been upset. This has occurred for the last three years and has been aggra- vated by the extreme dryness this year resulting in the worst conditions they have had. In addition to complaints received by the Dept. of Public Health, there have been numerous complaints filed with the Div. of Plan and Game, Dept. of Natural Resources, State of California. Investigation consisting of inspection and bacterial analysis of sewage effluent confirms that the plant is greatly avarloaded and is pro- ducing an effluent for below that required by conditions surrounding the disposal, so well as those WrescribeA by the permit. The history of the plant indicates that there war never a comprehen- sive industrial waste survey to determine the industrial load on the plant. It her been found that although the population, Sneluding the human population of Calif. Polytechnic School, is slig}fUy under 14,500 and the design population was 20,000 the nopuletion equiv. if the indus- trial loading is from 14,400 to 19,200 people. Since the present oversee daily flow is approx. 2.0 mpd end the plant was designed to handle an avorege flo•a o' %P5 mgd with a per. flow Of 3.9 mgd, it is seen that the plant is greatly Overloaded functionally. The chlorinated effluent was discharged into SLO Creek. In a bac- terial analysis �f this effluent on 13 samples 69�, of the samples showed e MFK of 70s/co; 7.7% showed s 11PN of 24/00, 7.7% showed a MPN of 70/ea; and 15.4`%showed a MPN of 2.3/ac. This indicates a high sewage conteri- nation going into SLO Creek. San Luis Obispo Renot1P-- page 2 • Conclusions: The terms of the permit granted Aug. 22, 1946 end amended Dec. 12, 1946 under which the City of San Luis Obispo Is now operating this sewage treatment plant are being violated. Some of the conditions of the permit and the deviations therefrom are listed below. (1) "No sewage or sewage effluent or impure water, gas, vapors, oils, acids, ter, solvents, or any other :patter or substonee offensive, injurious or dancer -us to health shell be disposed of into San Luis Obispo Creek in such quality or quantity as to be a public nuisance, offensive or den- aerous to health." Sewage effluent was discharged into S.L.O. Creek such that is was a public nuisance and a menace to health. Complaints have been received indicating unpleasant odors from as far as seven miles below the sewage plant. Cows have access to the oreek, constituting a health menace. Too, there are auction lines in the creek taking water therefrom. (2) "Waste-produoing industries interferinc with the proper opera- tion end funotioninr of this sewere disposal system shall not be permitted to sewer to this plant." Piggery wastes from the Calif. Polytechnic School are permitted to enter the sewer system. 4Fiteosky's Slaughter House, by contract with the city, is permltted to ,so the sewer system. These two industries are located outside the city limits. within the city limits the creamery wastes (Harmony Valley Creamery and Golden State Creemerv) have been per- mitted to enter the city sewer system. (3) "recel matter, sere.ge grease, garb a ge, solid matter, or oily sleek, or discoloration recognizible as of sewers origin from the sewer system of San Luis Obispo shall not be narmitted to be visible in the San Luis Obispo Creek except that unavoidable discoloration from said sewer system and sewage treatment plant may be permitted in the vicinity of the outlet." white, milky discoloration definitely established as that of whey was noticed five miler, below the sewer plant and being proportional to the distance therefrom. (4) "Insofar as the sewage of the city of San Luis Obispo is con - earned, the waters of the creek shall be maintained on a definite oxygen - containing besis, free from sludge banks and deposits and sufficiently low in sewage banterin to prevent menace to healt* of human beings and animals." Powere berteris at effluent disposal are 3n the order of 70+ coli- form/cc. DO tests showed: 1 mile below sewage treatment plant - Thursday, May 8, 1947, 1:00 pm -- 4.2 Ppm Friday, !day 9, 1947, 2:00 pm -- 5.1 ppm, showing a definite oxygen deficiency. (5) "There shall be no noxious of offensive odors or fumes of rowers origin attributable to the sewage of the city of San Luis Obispo in the waters of the creek, nor in the air outside the tract of land uson which sold treatment is located, such that the condition may constitute a pule as Odors have been reported as offensive from as far as seven miles bele, the plant. San Luis Obispo Repor•-- page 3 • (6) *Tao condition or conditions shall exist or be permitted to exist which may constitute a hazard to the health of human beings or animals or which may constitute a public nuisance under the laws of the State of California'. Sewage odors noticed seven miles below plant. Also, milch cows have access to the creek. (7) •Sewage effluent utilized for irrigation purposes or the sewer farm or on other lands shell conform to the State Sewer Farm Regulations and to any special reouiremerts reculred by the State Dept. of Public Health. No sewrawe or sewage effluent shell be allowed to be spread on or along any publ.ioroads or onto the lands of neighbors, or to be spread within such distance of roads or private property or wells or of San Luis Obispo Creek in such quantity or of such quality as to become a public nuisance, offensive, injurious or dangerous to the health of residents, travelling public or animals. The periphery of the sewer ferm and all areas irrigated under this permit shell be leveed where necessary to confine the sewage effluent and factory drainage within the lends covered by this per- mit. Private lands other than the sewer farm utilizing the sewage effluent shall receive approval from the State Dept. of Public Health in each instance.• Sewage effluent was used this year by a Mr. 'Frank D. 1011va with no permit from the State Dept. of Public Health. The sewF^e effluent was of such condition and used in such a manner that there ors!, a comple.lrt by Mr. Ruden of Pacific Motel neighboring the farm. Detailed Information Permit. The ➢emit of December 10, 1941 was for the enlargement of the exist- ing plant and the construction of a two -stage complete treatment bio-filtre- tlon plant. The conditions of this permit state that only properly chlorinated and oxidized sewewe shall ever be diseher{-ed to San Luis Obispo Creek. The entire plant, sewer farm and sewage disposal shell be without nuisance to neighbors or to the public. Permit letter of August 22, 1946: "Application of the City of S&P Luis Obispo dated duly 16, 1946, asking for permit to constnict oertein edditiors to the municipal sewage treatment plant, notably the addition of was collection and heating equip- ment in the sludge digester, and a eoncelnutor, with certain other minor changes, has been considered by this Department. •In substsnee, this epplicatior amounts to a request for amendment to the permit .-rented necer.ber 10, 1941 for the construction of a two - stage biofiltratlon plant at the City sewer farm. That permit allowed the omission of the gee holder roof from the then existing sludge digestion t^nk, thn omission of a comninutor and the omission of a sludge mixer and heat exchangers in the primary digestion tank contemplatedin the per:cit at that time. In other words, the present application merely supplies the omissions found necessary in the original plant. •rlth the above facts in mind, permit 1s granted as applied for, re- placing the permit granted December 10, 1941 and subject to the following conditions and terms: San Luis Obispo Report -- Page 4 "(1) No sewage or sewage effluent oY impure water, Ras, vapors, oils, acids, ter, solvents, or any other matter or substance offensive, injurious or dangerous to health shall be discharged or disposed of into San Luis Obispo Creek in such quality or quantity as to be a public nuiaanee, offen- sive, injurious or dangerous to health.

Director of Public Health History: The first sewers were built about 1892 duapirg sewage to the creek. In 1900 eeweee was moved about 1/2 mile out of town end a septic tank with stone filters was built, discharging into the creek. In 1910 the ease works were duplicated on a 7-sore piece of plowed ground which the City owned, adjoining a cemetery. About 1916 the present 48-sore newer Perm wee obtained end the filters were out of use. The septic tanks were continued to be used. At first a flume wee used to convey the sew0fre upon the farm and later this was replaced by pipe. 31ost of the sewage was used on the farm is the early years, but occasionally it was discharged to SLO creek. In 1926 a Herdinge clarifier and separate digestion tank (open) was built, with sludge drying beds. 1938 - the sewage at this time included some milk plant waste. The acreage of the sewer farm is just about edecuete to handle the sewage in the heat of the summer without inter- fering seriously with crop oroduotion. During. the remainder the year it is necessary to find additional acreage to prevent the seirer farm from becoming water logged. The soil is coarse, black loam with a high degree of porosity such that everege rates of aewrae of 200000 to 25,000 gale. Per acre per dap are poseible in the dry season. In 1941 application wee :wade for the enlargement and conversion of the existing plant to a two -stage complete treatzrert bio-filtretion ?lent with disposal of effluent onto the city sewer farm end excess flows to San Luis Obispo C-eek after chlorination. A two -stage biofiltretion with re- circulation, including in addition to the Hardinee clarifier, a primary clarifier and secondary clarifier, wee built and placed in operation in 1943. In 1944 a contract was consummated with Mr. Delidio wherein he leased the city sewer farm for a period of three years, contract being finished ran Luis Obispo Report -- page 6 • Oct. 11, 1947. In 1946 application war mede for the construction of certain omissions in the 1941 contract; namely, eomminutors, digester sludge gas collection and heating equipment, and miscellaneous pipe work and appurtenances for odor control. To date this has not been finished. General: The community 13 essentially residential and almost comnletely revered. Sewers is normal domestic sewe,e with discharges of milk wastes, piggery wastes from the Calif. Polytecbnic School, and wastes from ■it- cosky`a Slaughter Fouse. Rainfall is light, averaging 12 to 15 inches. Prevailing winds are from the northwest.

Poly- technic School piggery wastes entering the sewer system, in addition to the residential population. Cre�amr�ieq: The excess milk during the spring months goes prin- cipally into the manufacture of casein. In addition some cheese Is menu - featured. The waste product in each cage is whey. This is the waste that is going into the sewers. Casein whey is more Reid end hogs don't care too much f^r 1t es feed It to therefore, herder to dispose of then the cheese whey. The c*eeee whey Is sweat and mates a good feed for hogs. The farmers generally haul it beck for t^.is purpose. F.owever, some days the farmers arrive late and one batch of cheese may already have been made -- the whey going into the sewers. No provisions aveileble for storage for a short period. As was seen, there was a slight creamery load in 1938. This apparently had little effect on the plant. In 1941 there was a large production of casein. This Load fell off during the war years although It •cgs consider- ably larger than in the late 1301s. In 1945 the load began building up and wen very large this year. It is estimated that 2.7 to 2.8 lbs. of casein ere pro^ueed per 100 lbs. of milk. The remainder is a waste pro- duct in the form of whey which is discharged into the sewers. A popula- tion ecuiv. of 1600 per 1000 gals. of whey (8600 lbs.) is allowed.

Ffforts of this creamery to dispose of thin whey to eonden- series or for feed have bean in the large fruitless. The city has been hauling 1600 Fels. to the city dump. The dump is fairly well isolated although it is Adjacent to a secondary county road. After ten days haul- ing, no adverse affects were noted at the Hump. Arrangements were finally made to haul 2500 gallons of whey to Santa Maria for hog feeding. This began. April 24, 1947. Due to decrease in production, the city stopped hauling to the city dump on May 5. On resuest of this Dept. May 9, Mr. Fowell, Commissioner of Public Works, said that the city would start hauling again, taking whey from this creamery and also from the Golden State Co. This, coupled with Farmony Velley haul of 2500 gals. to Santa Maris, would keep all the whey out -f the sewers for the, present Reviewing the loadings of both Golden State and Harmony Valley, it Is seen that eomethir� like from 9-12,000 gals. of whey have been going into the sewers for a time. This at 1600 per 1000 gals. gives a popula- tion equiv. of 14,400 to 19,200 people. Witcoak 's Slau hter house: This industry located outside of the ally m to as .een operat ag since Dec. 1946. By resolution of the city enuncll they have been allowed to discharge their wastes Into the city sewer system. They pay a flat rate per animal killed: calves 51, beef 8#, hogs 30. This contract with the city may be terminated on 30 days' written notice.

California Pol technic Colle.e: The city contracted on Aug. 25, 1946, w th his ec. oo Lo .and o t air sewage, to be paid on a gallonage basis. Since no meter wa available they make payments on a per capita basis. There are presently 1000 residents and 850 non-residents at the school. A piggery is operated in connection with the school. At first wastes from this was allowed to run down through SLO and eventually reached the sewage treatment olent. This created a nuisance, so the city told them to run the wastes into the city sewer system. This is not covered by their contract. They average 250 hogs and about 2/3 of the pens are connected to the drain. The pens are weshed once a week. The bulk of the manure is picked up for fertilizer. Sue. erizing the industrial werte londing, it will he seen that there are several other small industries. 1 San Luis Obispo Report -- page 9 Summary of Industrial Waste Loading: Brendlin-Rice Frozen Foods -- fir.

Pan Luis Obispo Report"-- page 12 • A combination of factors of the treatment plant itself have compli- cated th6 situation: The grease rising in the Hardinpe clarifier is not removed. The opera- tor hoses it so that it is broken up and passes to the ;Primary clarifier. The secondary bio-filter was shut down for repairs Mar. 12 and Put back into operation Mar. 19. During this period the effluent from the primary bio-filter was split between the primary and secondary clarifiers. A month later the growth on the filter wasn't yet normal. Say 6th inspec- tion showed it to be normal. Then because of an overload on the digester which resulted in foaming, the operator withheld sludge by allowing it to build up in the primary clarifier. To this time the operator has been unable to completely pump out all the sludge from the clarifier. On one occasion the sludge was pumped directly from the clarifier onto the sludge beds. Tt was noted thet the sludge was practically dlrested, being very dark end having nracticelly r_o odor. Rising patches of dark sludge are evidence that considerable sludge still remains in the pri- mary clarifier. As an emergency measure to keep the effluent from going directly into the creek, the city constructed six holding lagoons approx. 35'x5O' x 3' deep, thlnki" to hold the effluent far a few days only and then turn it Into the VLO creek. The dikes for these lagoons were pushed into place with a bulldozer, there being no compaction or other working of the earth in these dikes. Effluent 'ass turned into the lagoons on Apr. 26. On Apr. 30 the dike nearest the road of the Northern group broke and permitted the effluent to flow onto the street and into a neighboring hayfield. The affluent was then turned bank into SLO creek. Mr. Howell reports that commencing May 12-14 for a two months' period Mr. Dalidio will use all of the effluent from the plant on his leased city sewer farm for the purpose of irrigating auger beets growing thereon. In the matter of chlorination of the sewage effluent It has been the practice to maintain, if poselble, a chlorine residual of about 0.3 ppm. It has not been possible, however to hold a residual during the late afternoon peek flow. The application of another 200 lbs. per day chlorinator makes it expected that it will not only be possible to main- tain a high residual, but to have some extra capacity for odor control and to help rehabilitate the primary bio-filter. The extra chlorinator was obtained from lwallace 3 Tiernan and installation, supervised by eorge White on Saturday, Mar. 29. It wes not until Apr. 10 thet any effort was made to operate the new machine. It was not possible to chlorinate to the full capacity of the machines because of small injectors. New injectors were ordered and installed. Full operation was commenced Apr. 25 end it has been operating continuously shoe that time. There have been no beetarlal analyses made since both chlorinators have been opera- ting. Results of bacterial analyses made of the effluent during the operation of the single chlorinator are ea follows: (see next page) Ben Luis Obispo Renor£ -- Pepe 13 • Date affluent 1 cc .1 .01 Residual ppm Pressure (pal) March 26, 1947 10:15 a.m. ++ ** ++ .75 125 • 27 11:15 " ++ -- -- 1.0 175 " 28 12:15 p.m. ++ -- -- 1.0 200 " 29 1:15 • ++ ++ ++ 1.0 160 ^ 30 2:15 " ++ +♦ ++ 1.0 150 " 31 2:15 " ++ ++ +- 11.0 175 April 1 3:15 " ++ ++ ++ .n 165 " 3 4:15 a ++ ++ ++ .025 190 " 4 5:15 " ++ ++ ++ ,} 175 " 5 6:15 " ++ ++ ++ .25 160 " 5 7:15 " ++ ++ ++ .2 175 • 6 8:15 ++ ++ -- .15 163 " 7 9:15 ++ ++ ++ 0.00 170 Teats for BOD and suspended solids were run by Mr. O.C.

The chlorinators operate, with a water sunnly from a shallow well on the sewer farm property. This water is furnished by an injector type pump, capacity 30 ". There is an auxilliary water supply, the plant effluent, furnished by an auxilliary pumn in case of failure of the other pump• However, both pumps operate from the same power supply. There is no other source of water avEilcble at the plant end in the event of a serious power stoppage, there. would be no water r.vaileble for the operatlom of the chlorinators. This means the treatment would Consist of primary clarification without chlorination. Survey of S.L.O. Creek: The headwaters of this creek ere in the mountains to the northwest -sl of the city. There is little likelihood of contamination of the stream before it enters the city. The flow of the creek through the city is steady but smell. The aster is clear and there ere no signs of degrede- tion. One mile above the sawape treatment plant the stream bed of the creek is dry. Airing the first part of this March, April and May all of the sewage effluent (ay. flow 1.8 mgd) was being discharged into the creek.balew At the time of this survey, May 7, the Creek below the sewac-e treatment plant tad a flow of from 2-3 mgd.. It is eerily seen that almost the entire flow of the creek Is sewage effluent. At station S,1 approx. l mile below the plant t.iere were sipne of depredation of this creek, conditions naturally being roughly proportional to distance from the plant. The water was turbid and the stream bed covered with a fungus growth.oeks in the stream bed were also covered with a slime similar to that found in trickling filters. On digging into the stream bed itself, it was found the ground was black end had septic odor irdieetira the deposition of sludge. Dis- Jeolvea orypen tests at this station showed: Date Time Tema.

There are two grade -A milk dairies located on SLO creek below the plant. These dairies are: Santa Fe or Rome Dairy with 75 cows, and the Merino Dairy with 50 cows. At both dairies the cows have access to the creek. In addition, there has been reoorted from i to 5 small dairies for manufacturing milk located on SLO creek. they each have from 10 to 12 cows, all having access to the creek. Use of effluent for irrigation purposes: In June 1938 San Luia Obispo asked for a blanket permit to use sewer* effluent for irrigation purposes within certain defined areas. With cer- tain conditions, this was granted. When it was desired to use the ef- fluent on s farm within this area, the farmer applied to the County Realth Office for permission. The Count Health Office orovided inspec- tion to see that the regulations of the Late Sewer ?arm Regulations and any special regulations required by the Dept. of Public Health were lived un to. This system had been used previous to this time. There are records of the use of sewage effluent ^or irrigation hack to 1930. 97. the use of levees and requirement of keeping sewnre effluent 800' .from highways rnd 100# from wells, nuisance was kept at a minimum. There are several farms in the, area that could use sewage effluent for irrigation purposas under groper superviaion and ins-,aotion. There are two farms which have used the sewage effluent for irriga- tion purposes this year -- Mr. Silva, without a permit And in such a manner e1 to cause oo olRint by the Pacific fgntel, end xtr.

The lease ex?ires Oct. 31, 1947. Mr. Howell has indi- cated that the city will not renew the lease. • STATE OF CALIFORNIA • DEPARTMENT OF PUBLIC HEALTH ..NEA, OF *ANITARY ENGtNaERING 10 LOBANGELEDC12).

"ALVIERIDON, W.15, February 20, 1947 City Council City of San Luis Obispo City Hall Son Luis Obispo, California Gentlemen: I appreciate the opportunity afforded me of meeting with you on February 18 to participate in the discussion of your sewage disposal problem. A re -inspection of the sewage treatment plant and environs, in the company of representatives of your City Engin- eering Department and Health Department on February 19, indicates clearly the gross overload which this system is receiving. Not only are there offensive odors at the plant, but the sewage is so inad- equately treated that the material going to the stream creates sewer conditions downstream from the plant. Such conditions indicate that at the earliest possible time a determination of the loadings and appraisal of the adequacy of the separate units of the treatment plant should be made. Follow- ing this, the necessary measures should be taken by the City to oor- reot the conditions. While a close estimation of the domestic sewage component of the load may not be difficult to determine, the popu- lation equivalent load attributable to Industrial sewage in the sys- tem will require a detailed survey of ell industries, getting not only the volume of waste flow (metered water consumed), but also an estimation of the strength of the sewage, either by measurement of flow and laboratory analysis or by a determination of the quality of material processed by the various industries. While this may be time-consuming for each industry, there are relatively few industries and thus the survey will not take a long period of time. I believe that your Engineering Department understands the several factors involved. Once the basic field investigation is developed, there remains the decision regarding methods to be followed to effect corrections; after which, as you know, the works must be designed, financed and constructed. Pending correction of existing conditions, all available temporary measures should be taken to mini- mize as much as possible the unsatisfactory conditions. One re- quirement should be that there be no interruption in chlorination of the effluent. The presently used single chlorinator having a single tank feed and a water supply subject to interruption during power outage or breakdown of puma does not meet the need for continuous r vicToaxchlorination. BUY E1S.0 M City Council, San Luis Obispo -2- February 20, 1947 We shall be glad to discuss with you and your representa- tives any phase of the program you desire, and we certainly wish to review methods and proposals for correction when the planning is adequately developed.

STATE OF CALIFORNIA DEPARTMENT OF PUBLIC HEALTH December 12, 1946 City Clerk San Luis Obispo California Dear Sir: In reviewing old and outstanding sewage disposal per- mits, as recuired by the resolution of the State Board of Public Health ilarch 11, 1946, we find that the recent issuance of per- mit on August 22, 1946 to construct additions to the municipal sewage treatment plant comprising sludge heating equipment, com- minutor, etc., replaced the :permit issued to the City December 10, 1941 for the existing clarifiers and biofilters, and covers the entire sewage plant as it will now be modified. V.e find also that the follo-Ang older permits remain outstanding: (1) June 30, 1928 - permit for the existingr_ardinge clarifier and continued use of the City sewer farm.

F'slverson, ".D. Director of Public Health V H: gulp age; • STATE OF CALIFORNIA • DEPARTMENT OF PUBLIC HEALTH CALIF. I M6 1........... May 11, 1946 City Council San Luis Obispo California Gentlemen: The subject of this letter is to take up with you com- pletion of certain features of the City sewage plant for which funds were not available when the plant was constructed. The occasion for this is the recent complaints, whose validity we do not in the least doubt, of odors along Highway 101. May I at the outset give my regrets to those of your officials who came to the plant Wednesday expecting that I would arrive that day. I did not reach San Luis Obispo until the following day. There are two obvious sources of odors around the sew- age plant. One concerns the ammonia and dank smells of fairly fresh sewage which is particularly strong at the two sewage fil- ters and is the more intense at No. 1 filter. The worst odor, however, I believe is that coming from the open sludge digester and from the release of undigested sludge onto the sludge drying beds. The odor first mentioned will be difficult to reduce except by housinS over the filters and treating the exhaust air. For the present, I believe this question had best remain in abey- ance and concentrate on dealing with the odors from faulty sludge handling. The sludge digesters were not completed in the original construction for lack of funds. As a result, one of the digesters is open to the atmosphere and all the foul gases escape directly and, furthermore, neither of the digesters is provided with sludge heating to carry on bacterial sludge digestion during the cold winter months. In consequence, just as soon as the warm weather of springy; starts up there is a great increase in sludge decomposi- tion due to increased bacterial activity until the winter deposit of sludge has been consumed by the bacteria. During that period there is a tremendous increase in the rotten gases of sewage. The orthodox relaedy for this problem is to enclose the digesters so that the gases given off may be collected and burned and, second, that the sludge entering the system should be heated so that digestion continues right through the winter. This defect h2 - 5/11/46 City Council will obviously have to be cleared before any statement of ade- quacy can be rendered your sewage disposal by this department in connection with obtaining the funds from the $90,000,000 City - County Fund. That is a requirement of the Act. I therefore recom- mend that the City proceed at once to put its sewage disposal plant in order, not only to meet the complaints but to be in the clear with respect to this City -County Fund Act.

One is that I do thins- that insofar as it con- tinues to be profitable the city would do well to depend on P:ir. Jens the desiCner of this plant to work out its difficulties. Second, however, I think it might now be re_nrded as not the best plan to have leased tre sewer farm, at least not until this sewage plant has passed through quite a long, trial period and its idiosyncrasies are mastered. 113th t::at in :.ind would it not be well to broach to the city the non -renewal of the lease as soon as it can be done with fairness to all concerned. The reason I advise this is that this: sewage dis- posal of San Luis Obispo is really in a critical and quite eaactinC neighborhood and it will certainly leave the city in better position to deal fairly with the neighbors if the sewer fars is. retained for quite a whlla as an adjunct of its se,zage dia,sosal. I know that was what we !is(' In mine.. when t,i:, city asked for permit for this plant, and in fact we contemplated that only effluent would ;-o to t:.e riv--r in excess of the cuanti y that t:ao se'„er f;,r, would not uroperly assimilate.
