What was observed was asphalt residue that was left behind/dumped at the rear of the dry cleaner by the ashpalt company after they repaved the parking lot. It has since been addressed and no further action is expected. Photos are enclosed. end.

The tasks specified in the order were accomplished. However, we still consider it important that you maintain and monitor the wells you installed. A subsequent sampling detected PCE in groundwater downgradient of your business at a concentration in excess of that which you found upgradient of your site. Now that the drought is over, we request you have your wells resampled this fall (October) and next spring (March). This request is made pursuant to California Water Code Section 13267.

Subject: PCE plume under 101/Prado Upon Caltrans review we discovered that there is a Petro-c.hloroethylene (PCE) plume under the project area. Caltrans provided a map and a contact. Y called Richard and asked questions about the plume. Toe said that it is in the shallow groundwater, which is located approximately 24 feet below ground surface. The concentrations of the PCE within this groundwater arc four tunes the maximum contaminate levels. He said that the plume came- from two dry cleaners. One located at 331 Pacific Street, which is now a kayak company, and one located on Higuera Street. Mr. Alshire said that he does not anticipate that our project will have an effect on the plume, or that the plume will have an effect on the project. If any de -watering is to occur, the water should be tested to see if it is clean. If it is not clean, then the water should be pumped from the ground and treated before it is released. This should occur only if dewatering is necessary_ SEP 28 2000 2027 916 739 0626 PAGE:. E a Sent B..

Date: 10102/00 Pages: 1 of 6 MEMORANDUM TO: Bill Hetland, Utilities Director FROM: Bob Neumann, Fire Marshal BY: Michael Smith, Hazardous Materials Inspector*) DATE: December 20, 1990 RE: Investigation of Possible TCE/TCA Groundwater Contamination - 214 Higuera St. BACKGROUND Earlier this year, the Regional Water Quality Control Board (RWQCB), contacted this office and requested information on businesses that use or have used TCE/TCA as part of their operations. At that time, the RWQCB was initiating an effort to investigate the groundwater contamination at the Dalidio wells. A review of Fire Department records for 214 Higuera Street, Paul's Dry Cleaners, indicated that a 1,000 gallon underground storage tank containing a dry cleaning solvent was in operation from 1952- 1987. This is significant since the average life span of an underground tank is approximately 15 years, under ideal conditions. Furthermore, because this tank was located inside the existing building, its removal, normally required, was waived and in 1987 authorization was granted for the abandonment and closure -in -place of this tank. It is important to note that during the tank abandonment process, an assessment of the area should have been conducted in order to verify whether the tank had lost any of its product into the surrounding soils or groundwater. This step was not done and the case was closed by this department. CURRENT With knowledge of the City's ongoing treatment of contaminated groundwater at both the Auto Parkway and Tali assumption that all dry cleaning operations only use perchloroethylene as their cleaning agent, I had considered this site as a potential point source, or at least contributor to the existing TCE/TCA contamination. This, however, is not the case. Upon further investigating the operations at this site and consulting with experts in the field, it was learned that petroleum solvents, namely stoddard solvent, is also used as a dry cleaning agent. Records show that the underground tank a 214 Higuera Street was used to store this type of petroleum solvent. It contains only aliphatic hydrocarbons. No chlorinated compounds are present. Only until recently (ten years ago), did the operators at this facility change over to perchloroethylene as their primary cleaning agent. In doing so, they also installed new equipment, which operates as a closed system. The perc is added directly to the equipment from drums or cans, not from the underground storage tank as previously thought. Accordingly, none of this product is discharged into the environment, except as air emissions. Therefore, based on this information, it is my recommendation that there is insufficient evidence to support any further investigation of this site. The products stored in the abandoned underground tank are not consistent with the compounds currently impacting groundwater. If there is still concern regarding the TCE/TCA contamination, existing City well data should be reviewed in conjunction with off -site analysis in order to characterize the contaminated zone. If you have further questions, please call me at extension #380. cc: Michael Dolder, Fire Chief Memorandum UNOCALS City of San Luis Obispo 728 Pismo Street San Luis Obispo, Ca. 93401 Attn: Michael Smith Dear Mr. Smith: December 5, 1990 Twl- d �w 5 L The attached Material Safety Data Sheets (MSDS's) for the products you have purchased from Unocal Chemicals Division have been carefully prepared in an effort to meet the worker right -to -know laws and to provide information necessary to your employee safety training program.
