BACKGROUND The applicant is requesting authorization to install soil vapor extraction equipment at the existing ARCO gasoline service station located at 14231 Red Hill Avenue. The vapor extraction system is needed to remove hydrocarbons found in the soil, and is required by the Orange County Health Care Agency. The ,subject site is located on the northwest corner of Red Hill Avenue and Mitchell Avenue . Adjacent land uses include a shopping center to the north and west, and residential uses to the south, and east of the project site . .at Zoning Administrator Report Design Review 9'6-023 l July 1, 1996 -- Page 2 PROJECT DESCRIPTION The proposed soil remediation system is a self-contained unit designed to treat contaminated sites by extracting hydrocarbon vapors from the soil. During the initial phase of the remediation, the vapor extraction system will employ a therma/catalytic oxidation process which burns the hydrocarbons then releases the filtered exhaust into the soil. The air sparging system which returns the exhaust is intended to enhance vapor recovery and natural bioremediation. Phase I remediation will be carried out for as long as the Total Petroleum Hydrocarbon (TPH) concentration in the inf luent, air stream is substantial. In the closing phase of the process, the vapor extraction system will use carbon-filled canisters to filter and remove vapors extracted from the soil. The vapors will be routed through the carbon vessels before . discharging to the atmosphere. This remediation phase will be continued until the site soil is remediated to achieve compliance with State regulations. The system will operate 24 hour a day and is anticipated to be needed on the site for approximately two (2) years. The remediation equipment will be located on the north side of the existing mini mart building. The applicant proposes to construct an eight (8) foot high mesh galvanized steel fence with plastic slats to enclose the remediation equipment. A Condition of approval has been added requiring that the enclosure be secured with a locked solid metal ; gate. A vent stack will project approximately four (4) feet above the top of the eight (8) foot high steel fence. The location of the proposed equipment will not obstruct any required parking spaces or impede on-site circulation. To provide compatibility with the site and surrounding area, Conditions of Approval have been included to require the applicant to paint the fence and gates to match the adjacent mini mart building, and the exposed portion of the vent stack to be painted by the manufacturer a neutral light grey. NOISE AND SAFETY J Issues associated with the proposed application include noise and public safety. These are discussed as follows: Noise -. Section 4614 (a) of the Noise Ordinance indicates that uses on commercially zoned properties shall not exceed 60 dBa at any time: The nearest residential property is approximately 100 feet southwest of the project site across from Mitchell Avenue. Zoning Administrator Report Design Review 96-023 July 1, 1996 Page 3 To ensure that the operation of the remediation equipment conforms to the requirements of the City Noise Ordinance, proposed Condition of Approval No. 3 .7 would require the applicant to muffle the equipment, as necessary, to meet the 60 dBa noise standard. In addition, the applicant will be required to perform a 24-hour noise test in . accordance with the City's Noise Ordinance to verify that the muffled equipment does not exceed 60 dBa at any time. - The applicant would be required to increase muffler devices should noise levels exceed the Noise Ordinance requirements. Proposed Condition No. 3 .4 has also been included to require the installation of a small sign indicating a contact phone number in the event of a problem with noise or the equipment. Public Safety - The Orange County Health Care Agency -permits and monitors all soil remediation procedures in the county. As lead agency, the Orange County Health Care Agency would certify when the soil remediation procedure has been successfully completed. The applicant states that the equipment manufacturer is in the process of obtaining necessary permits/licenses from the South Coast Air Quality Management District (SCAQMD) certifying the soil remediation equipment at the project site. Some of the vapors which will be present at the soil remediation site are considered volatile. Any risk of fire or explosion caused by the soil remediation equipment would be enhanced by the proximity to the existing gasoline service station operation. The applicant will be required to provide written notification to the Fire Authority regarding the start-up date of the remediation equipment, and the estimated completion date. pp; Rosa Ceja Assistant Planner Attachments: Location Map Site Plan, Equipment details Zoning Administrator Action 96-007 �' -- LOCATION MAP C Des eN �f.v it-it) 96 I ��tG �c�atiaV a + SC/U.E N FEET f � vsr 'iaee e:::.. r +� / f .
