This Letter of Understanding is a required condition of the draft Enforceable Agreement between DHS and ASCON. RECOMMENDATION• Staff recommends that the City Council authorize the Mayor to sign the Letter of Understanding and forward it, -to the DHS. ANALYSIS• On May 15, 1989, staff forwarded to the City Council a copy of the draft Enforceable Agreement between ASCON and DHS. The Enforceable Agreement designates DHS as Lead Agency for the site clean-up and establishes the procedures and responsibilities for the clean-up process. The City is not a signatore to the Agreement. The Agreement does, however, require that the City submit a Letter of Understanding to DHS agreeing to the designation of DHS as Lead Agency. On May 15, 1989, the City Council directed that the Letter of Understanding be prepared. Prior to the May 15, 1989 Council meeting, staff also met with the ASCON Ad -Hoc Committee to review the Enforceable Agreement with them. The Ad -Hoc Committee was pleased that DHS had prepared the Agreement, but was concerned that any public hearings related to site clean-up should be held in Huntington Beach, rather than in any DHS facilities out of town. In order to address that concern, staff has added language to the Letter of Understanding requesting that all public hearings be held in Huntington Beach. FUNDING SOURCE: No funds required. Pin FURS A ALTERNATIVE ACTION: The City Council may determine not to sign the Letter of Understanding. By so doing the Council would be stating that they do not agree with the designation of DHS as Lead Agency. ATTACHMENTS: 1. Letter of Understanding 2.

[ ] Yes [ ] New Policy or Ex ption RRIC Statement of Issue, Recommendation, Analysis, Funding Source, Altern n S. STATEMENT OF ISSUE: ASCON Properties and the State Department of Health Services (DHS) have prepared a draft Enforceable Agreement which would designate DHS as the lead agency for assuring site cleanup im compliance with the requirements of the Hazardous Substance Act of the California Health and Safety Code. Before ASCON and DHS enter into the agreement, however, the City must defer to the state DHS as the lead agency as set forth in a Letter of Understanding. The City will not be required to sign the Enforcement Agreement, but merely concur with it through the Letter of Understanding. RECOMMENDATION: Staff recommends that the City Council direct the City Attorney to prepare the necessary Letter of Understanding for submittal to DHS and inclusion by reference in the Enforceable Agreement. ANALYSIS• The designated Lead Agency for the ASCON site remediation will be responsible for all determinations under CEQA and for assuring compliance with the requirements of the Hazardous Substance Act. Due to the technical expertise and staff time needed to fulfill this role, there has been considerable debate over who should be the lead agency. At various times the City, DHS, Regional Water Quality Control Board and the South Coast Air Quality Management District have each been suggested for the lead agency role. After considerable negotiation between ASCON and DHS, the Department of Health Services has prepared an Enforceable Agreement which will designate themselves as the lead agency. The agreement would further designate the City of Huntington Beach and the Regional Water Quality Control Board as rsponsible�age'ncies. ASCON and DHS are in full concurrance with the terms and"conAitions of the agreement. The Regional Water Q-u_al ity;Con_troJoiBoard and the SCAQMD are also in concurrance. Plo 5/85 The Enforceable Agreement identifies the procedures which ASCON must follow in remediation of the ASCON site. Those procedures include; interim ground water monitoring, a Remedial Investigation and Feasibility Study (RI/FS), and a Remedial Action Plan (RAP). The agreement identifies the necessary components and procedures for each of those studies and plans. The Agreement also requires the designation of a Project Coordinator, a Project Engineer/Geologist, Quarterly Summary Reports, Quality Control/Quality Assurance, Agency Submittal Lists and numerous other terms and conditions. The agreement also requires that ASCON pay all costs required for site investigation and remedy by providing a letter of credit or performance bond to DHS in the amount of $1 million. In terms of compliance, enforcement and liability, the following conditions will apply. If DHS determines that any submittal fails to comply with the agreement, or otherwise fails to protect public health or safety, DHS may modify the document, return the document to ASCON for changes or make a determination of noncompliance pursuant to the Health and Safety Code. Any determination by DHS that activities are endangering health and welfare (whether or not covered in the agreement) may result in a Stop Work Order and endangerment abatement. ASCON may also be required to take further actions beyond those contained in the agreement. Compliance with the agreement will release ASCON from liability for any conditions or claims for past, current or future operations on the site. The agreement does not limit the ability of DHS to enforce matters not covered in the agreement, or from taking actions authorized by law to protect public health and safety. Under the terms of the agreement all of the remediation documents shall be submitted to DHS for review and approval. They must also be submitted simultaneously to the City, the Regional Water Quality Control Board and the State Superfund Program Manager. Although the City will defer to the DHS for approval of those documents, the City will be closely involved in their review. The City will also retain the right to approve a Conditional Use permit for site clean-up prior to remediation implementation. At the present time, ASCON has already prepared some of the documents required by the agreement. Principally, the Remedial Investigation (Site Characterization) has been completed and is being reviewed by DHS, Regional Water Quality Board and the City. While the agreement will not require that this document be resubmitted, it may require that additional information be submitted as deemed necessary by DHS or any other reviewing agency. The obvious next step for ASCON, under the terms of the agreement, will be to begin ground water monitoring, and begin preparation of the Remediation Feasibility Study. The Feasibility Study will identify possible remediation strategies and their impacts and levels of effectiveness. One strategy will then be selected and detailed in the Remedial Action Plan. After approval of that document, and approval of a Conditional Use Permit, site clean-up can begin. RCA - 5/15/89 -2- (2632d) Having reviewed the agreement and corresponded with the various affected parties, staff feels that the City's interests are adequately protected. The City Attorney has also reviewed that agreement and found it to be acceptable. Staff is therefore recommending that the City Council direct the City Attorney to prepare a Letter of Understanding for submittal to DHS and inclusion by reference in the Enforceable Agreement. FUNDING SOURCE: No funds required. ALTERNATIVE ACTIONS: The City Council may direct staff to relay concerns with specified portions of the Enforceable Agreement to the DHS, prior to preparation of the Letter of Understanding.

We appreciate this opportunity to provide the following comments to the proposed agreement. 1) The role of the Regional Board .in reviewing and approving submittals by the site owner must be clearly defined. The document, as'written, may lead the site owner to believe that only approval by DHS is necessary prior to commencing site activities. We believe that a statement should be included in the Agreement which declares that the Department shall not .approve reports, workplans, or changes and modifications to the operations at the site until input has been received from the responsible agencies, including Regional Board staff. The documents which.will require Regional Board staff review and approval consist of the following: • The RI/FS Workplan and its separate contents; • The Remedial Investigation Report; • The Feasibility Study Report; • The Draft Remedial Action Plan; and, • The Remedial Design and Implementation Plan. In addition, the interim ground water monitoring measures proposed by DHS must be reviewed and approved by this agency. 2) The Consent Agreement should note -that DHS will seek Regional Board staff comment prior to. authorizing Ascon to discontinue, move, or modify and or all of the remedial technologies that may be implemented as part of site cleanup, as identified in Section 3.4.6. of the agreement. e�11 Tu STATE OF CALIFORNIA ONVI HEALTH AND WELFARE AGENCY 'G'� FO(ZtDIST `!

II. BACKGROUND 2. Ascon Properties, Inc., is the present owner of the Site. 2.1. Background and History. The Site began operations in 1938, accepting brines and drilling muds from crude oil operations. In 1950, operations were expanded to include plating acids, refinery byproducts and other industrial wastes for disposal into pits and ponds on -site. Disposal of industrial wastes ceased in 1971, but construction debris and fill material was still disposed of over former waste pits. These activities ceased in 1983, when the current owners took over operations. The site now has 5 main waste ponds and an isolated pit containing a tar -like substance, which has been the source of several odor complaints from the local community. Because of these complaints, Ascon was ordered by the Orange County Superior Court to control the odors through an injunction issued by the South Coast Air Quality Management District. Investigations of the Site indicate that soil and ground water contamination exists beneath the property. 2.2. Natureand Extent of Contamination. According to Radian's report, the chemicals historically disposed of on -site include chromic and sulfuric acids, aluminum slag, magnesium and potassium chloride, fuel oils and oily wastes, mercaptans, styrene, styrene tar, dion isostyrene monomer (sic), polyester resin fractions, phenolic wastes, synthetic rubber, and construction debris. Investigations conducted at the site reveal Page 4 of April 19, 1989 ENFORCEABLE AGREEk 2 (DRAFT) ASCON PROPERTIES, INC. lead concentrations in soil as high as 2560 parts per million (ppm), in addition to slightly lower concentrations of zinc, barium and chromium. Contaminants found in ground water beneath the Site include alkylated benzenes, polynuclear aromatic hydrocarbons, styrene and toluene. 2.3. Pathways for Exposure. The Site has evaporation ponds on -site which contain oily wastes. Ascon has indicated that it would like to remove the oily wastes for recycling. During such a removal operation, if approved by the Department, volatile organic hydrocarbons, which may be present in the ponds, could be released into the atmosphere unless adequate measures are taken to prevent or control such a release. The Site also has several pits which contain plating acids and other industrial wastes. Disturbance of these pits may result in the release of vapors or hazardous particulates into the atmosphere unless adequate measures are taken to prevent or control such a release. In addition, the chemicals described in paragraph 2.2, which were disposed of on -site, may have migrated and may continue to migrate into the ground water beneath and adjacent to the Site. The Site is fenced; however, there is also a potential for direct contact with contaminated soils by persons on -site. Page 5 of April 19, 1989 ENFORCEABLE AGREED r (DRAFT) AS,CON PROPERTIES, iiJC .
