MINOR AMENDMENT SP 144 SAN DIEGO GAS I ELECTRIC COMPANY -Request
to rep 1 ace six uncovered wastewater co 11 ect ion 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
levels 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 -MINOR AME9tENT
June 7, 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, SOG&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 SDG&E to
complete the project by August, 1990. SDG&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 aspha 1 t 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 c 1 osed/removed in accordance with a II closure pl an II 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:
I} 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 SOG&E -MINOR .DMENT
June 7, 1989
PAGE 3
2) The low volume waste tanks wi 11 col 1 ect the same waste streams as the
ponds currently co 11 ect. However, there wi 11 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 i nvo 1 ve the addition of the o 11 so 1 ids coa 1 escer, 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 shown on Exhibit 11 A11 • The maximum cut will be 8 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 -MINOR ~ENT June 7, 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.

21. Analyze viable alternatives to the proposed project such as:
a) Phased development of the project, b) alternate site designs,
c) alternate scale of development, d) alternate uses for the site,

The project is being done in order to comply with the Toxic Pits Act of
1984. Phasing or a no project alternative is not possible. To comply
with the new law, SDG&E studied two alternatives: relining the existing
ponds or using steel tanks to hold the water. SDG&E chose to use the
steel tanks. While the tanks are the costlier of the two alternatives,
they are the safest and most environmentally-sound. The Regional Water
Quality Control Board has directed SDG&E to complete the project by
August, 1990.

22. Mandatory findings of signific·ance -
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?

18. The wastewater treatment tanks will be 18 to 30 feet in height. The existing
ponds are not visible. The tanks -will be constructed of steel and will be
visible from Carlsbad Boulevard. However, they will be painted a color that
makes them compatible with the existing landscaping that backdrops the site.
In addition, planting along the front perimeter of the site is incorporated
into the project for screening purposes.

IV. DETERMINATION (To Be.ompleted By The Planning lpartment)
on the basis of this initial evaluation:
_x=-_I find the proposed project COULD NOT have a significant effect on
the environment, and a NEGATIVE DECLARATION will be prepared.
___ I find that although the proposed project could have a significant
effect on the environment, there will not be a significant effect in
this case because the mitigation measures described on an attached
sheet have been added to the project. A Conditional Negative
Declaration will be proposed.
___ I find the proposed project MAY have a significant effect on the
environment, and an ENVIRONMENTAL IMPACT REPORT is required.
