BACKGROUND- On April 3 , 1986, Supervisor Torlakson wrote to this office and the Health Services Department bringing to the attention of both offices a specific instance in which an individual was unclear how to comply with new State laws and regulations pertaining to the permitting of underground storage tanks. The individual, Mr. George Clemonds, appeared before the Board of Supervisors on April 8, 1986 and described the problems he had had in having his underground storage tank removed once he determined .it would be too expensive to keep it and have it permitted. The Board requested an explanation of why the apparent confusions had occurred. In response, the Health Services Director has forwarded the attached report in the form of a status report, commenting on the particular facts involving Mr. Clemond' s situation and indicating that a comprehensive report on the development and current status of the underground tank enforcement program will be available within 30 days. This more comprehensive report will be forwarded to the Board with recommendations as soon as it is received.

DEPUTY � f 75 i CONTRA COSTA COUNTY HEALTH SERVICES DEPARTMENT To: Board of Supervisors via: Phil Batchelor, County Date: May 14, 1986 Administrator From: Mark F i nucane, Dire or Subject: Health Services Department,OQ,,,�� COMPLAINT BY GEORGE CLEMONDS By: Dan Bergman, Assistant Hea th TO SUPERVISOR TORLAKSON Services Director - Environmental Health The purpose of this memorandum is to address the frustrating circumstances detailed by Mr. George Clemonds to your Board concerning the process he experienced while attempting to comply with requirements of the "Sher" Bill and County Ordinance Code regarding his underground fuel storage tank. I would like to express my regret for the lack of coordinated response that Mr. Clemonds experienced and my inability to resolve his concerns during our initial discussions following his referral to me by Supervisor Torlakson on these issues. The State Water Resources Control Board regulations were in the process of being developed from 1984 through final adoption on August 12, 1985. The site specific requirements for implementing the underground tank law are contained in these State regulations and our jurisdiction in cities was limited to new facility installations prior to the promulgation of these State regulations. There are also a variety of exemption provisions that evolved including the following categories: • Motor vehicle fuel tanks located on farms used to fuel vehicles used primarily for agricultural purposes; ° Home heating oil tanks of less than 1100 gal . capacity; ° Tanks located at an airstrip and used to fuel aircraft for agricultural purposes; ° Tanks used to contain chemicals to control parasites on livestock in agricultural operations. In addition, specific statutory compliance dates were pushed back several times as a consequence of subsequent cleanup legislation based primarily on the failure of the State Water Resources Control Board to meet their statu- tory deadlines for adopting the implementing regulations. A-41 3/81 -2- Environmental Health Enforcement Policy is generally predicated on enforcing one legislative standard in both the unincorporated territories of the County and the incorporated cities. Consequently, specific policy and enforcement activities were not implemented for existing facilities until the State regulations were adopted, thereby, extending our jurisdic- tion over existing facilities to the cities as well . Interpretation and clarification of State regulations for compliance also depends to some extent on local site specific problems coming to our attention such as the circumstance detailed to me by Mr. Clemonds. It is always our enforcement intent to provide reasonable compliance times with minimal impact on regu- lated parties to the extent we can assure responsible compliance with the legislative mandates and absent a problem presenting a clear and present public and/or environmental health danger. Mr. Clemonds presented the following concerns in seeking my advice regarding his compliance options: - ° Mr. Clemonds had one underground gasoline fuel storage tank used to service his private vehicles; ° His facility appeared on our list from the Regional Water Quality Control Board because he complied with his requirement to report this underground tank in a RWQCB Survey conducted in 1985 as required by the Cortese Bill ; ° Mr. Clemonds was exploring his costs and options to determine whether to retain or abandon this underground tank; ° He wanted to know if any exemptions applied to his use as he also has several acres under cultivation; ° Mr. Clemonds wanted to know whether soil samples and laboratory analysis would be required if he elected to abandon his tank. I met with Mr. Clemonds to discuss his compliance options on or about Feb. 10, 1986. It became clear to me that there was a need to further discuss the matter with Mr. Benike in light of his prior conversations with Mr. Clemonds and a probable need to discuss exemption options with the State RWQCB staff to obtain their concurrence on any interpretations of State regulations that would facilitate Mr. Clemonds preferences. Mr. Benike was on vacation during the date of my conversations with Mr. Clemonds. Consequently, I told Mr. Clemonds that I would discuss compliance options with Mr. Benike upon his return the following week and with State Water Resources Control Board staff if necessary and then get back to him with our conclusions shortly thereafter. I did assure Mr. Clemonds that he would not be subjected to enforcement action by the Environmental Health Division during the interim pending my' obtaining clarification on the rele- vant issues and reaching subsequent agreement with him. I also advised Mr. Clemonds that he would likely receive subsequent notification from the County Auditor-Controller's Office in the near future as this billing and -3- followup process was now automatic. In an effort to prevent the subsequent frustrations and uncertainties described by Mr. Clemonds to your Board, I also advised him to hold all subsequent communications directed from our regulatory process and to communicate with me on these issues pending my clarification of his compliance options and possible exemption under the State Law and County Ordinance. I again assured Mr. Clemonds that enfor- cement action would not be initiated against him by Health Services prior to our having the opportunity to clarify and resolve all pending issues of concern and reaching a compliance agreement. With respect to the inspections conducted by fire services, I was not per- sonally aware of these requirements when I talked with Mr. Clemonds. I sub- sequently learned in discussions with Mr. Benike that fire services inspect abandoned underground tanks to assure proper handling and disposal in light of potential fire and explosion hazards pursuant to the Uniform Fire Code. This requirement is being added to the press release that will be sent out shortly advising the public of issues relating to the underground tank inspection program at the request of Supervisor Torlakson. I discussed Mr. Clemonds' compliance options with Mr. Benike when he returned from vacation. The exemptions do not apply to Mr. Clemonds' underground tank. Soil samples are expressly required by State regulations. Uniform Fire Code provisions expressly apply to underground tank removal , transport and disposal . Mr. Benike clarified these requirements with Mr. Clemonds and his underground tank has been removed at Mr. Clemonds' election. Program development and implementation on this scale involving over 1200 facilities and approximately 4000 underground tanks County-wide seldom occurs without some confusion. Timing and coordination is difficult with multiple jurisdictional responsibilities and when regulations are awaiting State adoption and promulgation. We have been regulating new facilities and tank abandonments for well over a year and have delayed full enfor- cement of the Sher Bill involving facilities existing prior to 1984 due to a compliance deadline that the State legislation has pushed back to September, 1986. Permitting each. facility, however, is fully underway. We are attaching information that had been sent to each facility owner for their information. It is unfortunate that Mr. Clemonds was caught in the early stages of this program field enforcement; however, his calling attention to the process issues that impacted him has been helpful to me in dealing more effectively with our compliance process. A comprehensive report on the development and current status of the underground tank enforcement program is being drafted and will be directed for your review and information within the next thirty days. DB:cbc (1 )Clemonds Contra Health Services Department Costa ENVIRONMENTAL HEALTH DIVISION County January 13 , 1986 Dear Underground Tank Owner : As you may be aware , the State Legislature has recently enacted legislation requiring the permitting and inspection of most underground hazardous substance storage tanks in California. A brief outline of this legislation is as follows: (9/23/83) - Sher Bill (AB 1362) effective. Required inspection and permitting of underground tanks used for the storage of hazardous substances. Permits when issued will be valid for five (5) years and are transferable. ( 1 / 1 /84 ) - Cortese Bill (AB 2013 ) effective. Required tank registration with the State Water Resources Control Board. (This mailing is based on the tank registration). ( 8/ 12/85) - State regulations written by State Water Resources Control Board adopted. Dates set in Sher Bill were exceeded before regulations were in place). ( 9/30/85 ) - AB 2239 effective. Set new compliance dates and added provisions for issuance of interim permits. 10/ 1 /85) - Bradley Bill (AB 1755) effective: Minor change in construction standards Tank testing interval extension for early testing. Compliance dates are : March 1 , 1986 for the issuance of interim permits to operate an underground storage tank; interim permits are valid only through September 1 , 1986 at which time standard operating permits must be issued. Operation of an underground tank storing a .hazardous substance without a permit may result in a fine of $500 to $5000 per day of operation (Section 25299, California Health and Safety Code) .

We are attaching excerpt from subchapter 16, Title 23 , Section' 2641 , California Administrative Code, for your information. It is expected that most service stations will use Alternate No. 5 for product , and No. 7 for waste oil . The monitoring plan should contain the following: 1 . Choice of monitoring alternative (e . g. #5) 2 . Detailed explantion of inventory control methods used . 3 . Description of how records are kept (please note that quarterly reports will be required - sect 2644 . e ) 4 . Tank testing dates , or copies of recently performed tests (within 6 months). 5 . Description of facility . 6 . Description of local geology (depth to ground water , soil type) . 7. Name , address and phone number of person responsible for cleanup of releases at the facility . 8 . Submit a Plot Plan showing the following: - Plot plan scale , key of symbols used - Location of all tanks and piping - Property line(s) - Buildings - Any surface waters within 200 feet of the site - Nearest intersection or road - Proximity to surface waters - Types of neighboring land uses 9 . Please limit submitted material to less than four pages if possible . Note: AB 1755 allows a 30 month interval before your next test if you test before March 1 , 1986. A letter from a tank testing firm scheduling your test , even if a number of weeks after deadline , will meet this requirement , as long as arrangements are made before April 1 , 1986. PRESS RELEASE In response to concerns expressed by some East County residents who own underground tanks used to store hazardous substances, Supervisor Tom To'rlakson has requested clarification regarding recently enacted state regulations being implemented by the Contra Costa County Health Services Department (CCHSD) . The applicable regulations have been developed by the California State Water Resources Control Board (SWRCB) in response to legislation introduced by Assemblyman Byron Sher, which became law on January 1, 1984. This state leqislation was enacted to regulate underground tanks storing hazardous materials in an effort to deal with groundwater contamination being disclosed in many areas of the state. This law requires the inspection, testing, and per- mitting of underground tanks used for storing hazardous substances, In addi- tion, inspection and soil testing are required when such tanks are abandoned or removed by both Contra Costa County Department of Health Services and Fire Services. Underaround tanks located on farms to fuel vehicles used primarily for agri- cultural purposes are exempt from these regulations. The SWRCB has defined a farm as an agricultural operation actually growing crops or livestock, and generating $1,000 net annual income, or more, from agricultural production. The tank registration data provided by the SWRCB and used by the CCCHSD as a basis for invoicing tank owners for permit fees frequently does not indicate that a tank is used for agricultural purposes. Permit fees being billed by CCHSD cover a five year permit time period. Contra Costa County Environmental Health Division staff will prorate the permit fees to a yearly payment basis upon request from tank owners. If a tank owner wishes to abandon an underground tank rather than obtain a per- mit for continued use, they must complete an abandonment form available from CCHSD and pay a required $100 per tank abandonment fee. This fee covers the CCHSD staff and administrative costs associated with site inspection and investigation for possible leakage or contamination problems that are reviewed at the time tanks are removed or abandoned in place. If you require additional information, please call CCCHSD, Environmental Health Division, at 372-2286. OB:rm 5/14/86 t TUm Torlakson 45Civic Avenue �_. Pittsburg.California 94565 _ (415)439-4138 Supervisor, District Five Contra Costa County - eoaro of Supervisors COUK� DATE: April 3 , 1986 TO: Phil Batchelor, County Administrator Mark Finucane, Health Services Director Attn: Dan Bergman, Assistant Health Services Director, Environmental Health FROM: Supervisor Tom Torlakson SUBJ: UNDERGROUND TANK PERMIT PROGRAM ------------------------------------------------------------ I have received the press release prepared by Dan Bergman to clarify the underground tank enforcement program permit fees and exemptions. I noted that no reference was made to required fire department permit for abandoning the tank. I learned of this fire inspection requirement from George Clemonds, a constituent who contacted my staff for assistance a few months ago with regard to the underground tank permit program. My staff in turn referred Mr. Clemonds to Dan Bergman who had previously explained that his office would deal with these situations on an individual basis. I am pleased to learn that contacts have been made with persons we have referred. The situation with Mr. Clemonds seems a rather unique one. During a telephone conversation with Mr. Bergman, Mr. Clemonds was told that if he received anything from the Health Services Department that did not have his signature on it, that Mr. Clemonds should "ignore it" as Mr. Bergman would be reviewing his specific situation. Upon receiving an invoice from the county, Mr. Clemonds contacted the Auditor-Controller' s Office and was told by "Barbara" to make this notation of Mr. Bergman' s instructions on the invoice and return it. When this ,invoice was received by Bruce Benike, an inspector in the Health Services Department assigned to inspect underground tanks, he sent Mr. Clemonds a letter informing him that the matter would be turned over to the District Attorney' s Office if he did not comply. Mr. Clemonds attempted to explain to Mr. Benike his conversation with Mr. Bergman. (Mr. Clemonds expressed frustration that there was no communication between Mr. Bergman and the inspector. ) i r, Phil Batchelor Mark Finucane April 3 , 1986 Page TWO After speaking to Mr. Benike who informed him that removing the tank would cost $100 for an inspection fee by Health Services Department, $62. 50 for a fire inspection, and if a soils analysis was needed it would probably cost around $86 , Mr. Clemonds made a decision to remove the tank rather than pay for a. permit which Mr. Clemonds, understood would cost around $750. Mr. Clemonds pointed out that it appears staff has embarked on this major program without first getting a clear process established. He commented that procedures seem to change from day to day. He was the first to go to the fire department for a permit and staff there were not real sure how to deal with him. His father-in-law applied for a permit the following day and was instructed to fill out forms that were different from what he had filled out just the day before. He also questioned the necessity for a fire inspection. He pointed out that when the fire inspector came out, the inspector merely asked two questions--Is that the hole the tank was it? Is that the tank that was in it? His wife responded affirmatively to both questions and that was the extent of the inspection. I think he poses a legitimate question: Why is it necessary to have two inspections, one by the Health Services Department (at $100 ) and another by the Fire Department ( for $62. 50) especially if the inspection by the fire department is in fact that superficial? Mr. Clemonds was told by another Health Services inspector ( "Hank" ) that a soils analysis would be needed and provided him with a list of labs: He contacted the closest lab and learned a soils analysis would cost around $450 which is quite an increase from the amount that Mr. Benike originally estimated for him. Mr. Clemonds pointed out that if he had been aware that a soils analysis would cost that much, he may have elected to keep the tank. I have gone into a great deal of detail about this particular constituent case to point out the desperate need for clarification ( and the press release helps ) , the apparent lack of communication between Dan Bergman and Bruce Benike ( at least in this particular case) , and the need to establish clear procedures, including the fire permit process . Mr. Clemonds has expressed a desire to bring this matter before the entire Board of Supervisors. Your prompt attention to this matter would be appreciated. TT:gro • a Inventory Daily /esti" 2646 1.
