May 3, 1989 PLANNING COMMISSION PLANNING DEPARTMENT STAFF REPORT MIHOR AMENDMENT SP 144 SAN DIEGO GAS & ELECTRIC COMPANY -Request to replace six uncovered wastewater collection ponds with six collection tanks at the Encina Power Plant, 4600 Carlsbad Boulevard located in the PU Zone and Local Facilities Management Zone 3. RECOMMENDATION That the Planning Commission ADOPT Resolution No. 2858 APPROVING the Negative Declaration issued by the Planning Director, and ADOPT Resolution No. 2859 APPROVING a Minor Amendment to Specific Plan 144, based on the findings and subject to the conditions contained therein. II. PROJECT DESCRIPTION AND BACKGROUND This item is a request by San Diego Gas & Electric for a Minor Amendment to Specific Plan 144 to install six wastewater collection tanks at the Encina Power Pl ant. Spec if i c Pl an 144 covers the entire Enc i na Power Pl ant operation. Because the new tanks will replace the six open ponds presently being used for wastewater collection and because the amendment only affects a small area on the power plant property, it is being processed as a Minor Amendment to the Specific Plan. Wastewater treatment at the plant currently involves the use of six open ponds and a physical/chemical treatment facility. There are two low volume waste ponds with 300,000 and 590,000 gallon capacity, two extended waste ponds with a 750,000 and 330,000 gallon capacity and two treated water ponds with 220,000 and 270,000 gallon capacity . The two low volume ponds hold wastewater which contains low 1 evel s of dirt and oils that make their way to the basement sumps. Sources include rainwater runoff and other low level waste such as water softener regenerant flow. This wastewater is similar to that which would result from activities like a homeowner washing a driveway, car washes or garages. The extended wastewater ponds are empty most of the time. They are used to hold wastewater from washing the power plant's four steam boilers. This process is necessary to increase the boilers' efficiency and reliability and is done about every two years on each of the boilers. The materials contained in this wastewater include trace metals such as iron, copper and nickel along with cleaning chemicals. These materials are removed from the water through treatment, solidified and taken to a licensed disposal facility. Although these materials are classified as hazardous, operating SP 144 SOG&E -.R AMENDMENT MAY 3, 1989 . PAGE 2 personnel are not required to wear protective clothing or breathing apparatus when handling them. The cleaned water is forwarded to the treated water ponds. The treated water ponds are used to temporarily store the water which has been processed through the treatment facility. At this point, samples are taken and analyzed before allowing the water to be discharged into the ocean. The proposed project would replace the open ponds with six tanks and is being done in order to comply with the Toxic Pits Act of 1984. This law set more stringent standards on the use of waste impoundments and their potential for ground water contamination. To comply with the law, SDG&E had two options: Relining the existing ponds or using steel tanks to hold the water. SOG&E chose to use steel tanks. While the tanks are the costlier of the two options, they .are the safest and most environmentally sound. The Regional Water Quality Board, which is responsible for ensuring compliance with the law has directed SOG&E to complete the project by August, 1990. SOG&E's plan has been 'approved by the State Department of Health Services which regulates the design of these types of facilities {approval letter is attached to staff report). III. ANALYSIS Planning Issues 1. Will the installation of the tanks improve the treatment of wastewater at the Power Plant and eliminate the possibility of ground water contamination? 2. Will the installation of the tanks at the proposed location impact or interfere with any other operations of the Plant including onsite circulation? 3. Have the visual impacts associated with above-ground tanks been adequately mitigated? DISCUSSION The proposed location for the tanks is in the area on the site that is presently paved with asphalt and used as a temporary storage area. Therefore, the installation of the tanks will not impact or interfere with onsite circulation or parking or any other aspect of the power plant operation. The existing ponds will be closed/removed in accordance with a "closure plan" approved by the State Department of Health. The installation of above ground tanks will virtually eliminate the possibility of any potential ground water contamination. Key features of the new system are: 1) The extended waste and treated waste tanks will function like the existing ponds in that they will collect and temporarily store wastewater before and after treatment prior to discharge. ,, SP 144 SDG&E -MINI AMENDMENT MAY 3, 1989 PAGE 3 2) The low volume waste tanks will collect the same waste streams as the ponds currently collect. However, there will be a new step in the treatment process. The low volume wastes will be treated in an oil and solids coalescer. This new system will continue to automatically filter and monitor low volume wastewater to assure that the discharge of these wastewaters complies with the plant's discharge permit limits. If wastewater does not meet specified limits the system automatically shuts down, making it a 100 percent backup system. 3) Because the new system will make the most effective use of the equipment and involve the addition of the oil solids coalescer, the amount of wastewater onsite at any one time will be significantly reduced. The extended waste tanks will contain 357,000 gallons, the treated water tanks will have a capacity of 95,000 gallons and the low volume wastewater tanks will hold 56,000 gallons. 4)" Each tank will be completely above ground to allow plant operators to visually inspect for leakage. The tanks will be built on a concrete pad that is designed to meet very stringent seismic criteria. The pad will be surrounded by a watertight, concrete containment block wall which will capture any leaks, in the unlikely event that any might occur. 5) Tank levels will be monitored continuously and high level alarms will sound in a control room which is manned around-the-clock. Additionally, there are provisions for each tank to overflow into the parallel sister tank should all systems fail. One concern that staff had was the visual impact of the tanks. The tanks will be 18 to 30 feet in height and 20 to 45 feet in width and will be visible from Carlsbad Boulevard. They will be small, however, in comparison to the existing tanks already located to the north on the property and currently visible from Carlsbad Boulevard. In order to mitigate the visual impacts staff is recommending, and the applicant concurs, to paint the tanks a color that makes them compatible with the existing landscaping that backdrops the site. In addition, planting along the front perimeter of the tanks is incorporated into the project for screening purposes. Some grading and retaining walls will be necessary to create a large enough pad area for the tanks as ~hown on Exhibit "A". The maximum cut will be B feet, the maximum fill will be 3 feet and the retaining wall will range from 1 foot high to 7 feet high. Because the proposed project will improve wastewater treatment at the Plant, will eliminate the possibility of ground water contamination and will not interfere or impact existing circulation or other onsite operation, staff is recommending approval of this Minor Amendment to SP 144. IV. ENVIRONMENTAL REVIEW The Planning Director has determined that no significant-environmental impacts will result from this project, and a Negative Declaration was issued on March SP 144 SDG&E -.OR AMENDMENT MAY 3, 1989 PAGE 4 17, 1989. This decision was based on findings of the Environmental Impact Assessment and field survey. The site is presently paved and used for storage. The project will replace six existing open wastewater treatment ponds and eliminate the potential for ground water contamination. Visual impacts of the project will be mitigated by landscaping and painting. The Negative Declaration was sent to the State Clearinghouse and no comments were received. ATTACHMENTS 1.

X X The project is being done in order to comply with the Toxic Pits Act o 1984. Phasing or a no project alternative is not possible. To cornpl: with the new law, SDG&E studied two alternatives: relining the existin< ponds or using steel tanks to hold the water. SDG&E chose to use th, steel tanks. While the tanks are the costlier of the two alternatives they are the safest and most environmentally-sound. The Regional WateJ Quality Control Board has directed SDG&E to complete the project b~ August, 1990. -6- 22. Mandatory findings of significance - a. Does the project have the potential to degrade the quality of the environment, or curtail the diversity in the environment? b. Does the project have the potential to achieve short-term, to the dis- advantage of long-term, environmental goals? (A short-term impact on the environment is one which occurs in a relatively brief, definitive period of time while long-term impacts will endure well into the future.) c. Does the project have impacts which are individually limited, but cumulatively considerable? (A project may impact on two or more separate resources where the impact on each resource is relatively small, but where the effecty of the total of those impacts on the environment is significant.) d. Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? III. DISCUSSION OF ENVIRONMENTAL EVALUATION Project Description: MAYBE NO X X X X 18. The wastewater treatment tanks will be 18 to jQ feet in height. The existing ponds are not visible. The tanks will be c9nstructed of steel and will be visible from Carlsbad. Boulevard.
