FACT SHEET
ENCINA POWER PLANT WATER TREATMENT TANKS
San Diego Gas & Electric is requesting permission to install six
wastewater collection tanks and associated facilities at the
Encina Power Plant. The new tanks will replace the six ponds
currently being used for wastewater collection at the plant.
Above ground tanks are currently the most environmentally sound
technology for wastewater collection and temporary storage. The
tanks will allow SDG&E to comply with the Toxic Pits Act of
1984. The ponds will be closed/removed in accordance with a
"closure plan" approved by the State Department of Health
Services, and the obtaining of all other applicable State and
Regional and/or local governmental entitlements.
CURRENT PROCESS
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.
Low volume wastewater 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
-1-
result from activities like a homeowner washing a driveway,
carwashes or garages.
This material is not considered to be hazardous by legislative
definition, and concentrations are small and the threat to
public health or the environment is considered to be extremely
minimal. About 99 percent of the time, low volume wastewater
falls within limits considered by the Regional Water Quality
Control Board to be clean enough to discharge into the ocean
without treatment.
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 personnel
are not required to wear protective clothing or breathing
apparatus when handling them. The cleaned water is forwarded to
the treated water ponds.
-2-
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.
LEGISLATION
In 1984, the California State Legislature accepted Assemblyman
Katz* bill setting more stringent standards on the construction
and operation of hazardous waste impoundments.
To comply with the new law, SDG&E carefully studied two options:
relining the existing ponds or using steel tanks to hold the
water. SDG&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 hazardous waste facilities. (see
attached letter)
THE NEW TANKS AND OIL AND SOLIDS COALESCER
The installation of above ground tanks and an oil/solids
coalescer will virtually eliminate the possibility of any
potential ground water contamination. Key features of the new
system are:
-3-
-- 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.
-- 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 redundant
backup system.
-- Because the new system will make the most effective use of
the equipment and involve the addition of the oil and solids
coalescer, the amount of wastewater on site 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.
-- 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."
-4-
-- 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.
-- The tanks will range from 18 to 30 feet in height and be
constructed of steel. 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.
-- The tanks, like the larger ponds currently in place, will not
be covered. Covering the tanks would create a danger to plant
employees who must go inside them for cleaning and observation
of water levels. Additionally, covering the tanks would
necessitate the project's redesigning and increase the cost.
And, although some of the materials inside the tanks are
classified as hazardous, they pose no danger to the environment
according to the Regional Water Quality Control Board and other
regulatory agencies.

YES MAYBE NO
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?
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.) x_
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? x
III. DISCUSSION OF ENVIRONMENTAL EVALUATION
Project Description:
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.
-7-
IV. DETERMINATION (To Be Completed By The Planning Department)
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.

II. STATEMENT OF NON-SIGNIFICANT ENVIRONMENTAL EFFECTS
If you have answered yes to one or more of the questions in Section
I but you think the activity will have no significant environmental
effects, indicate your reasons below:
The construction of steel tanks instead of relining the existing surface impound-
ments is an environmentally superior means of processing, treating and storing the power
plant waste stream. This methodology eliminates the potential for groundwater contamina-
tion that presently exists with surface impoundments.
The design and operation of the wastewater tanks and the discharge of the power plant
hazardous and non-hazardous wastewater is regulated by State Governmental Agencies to
insure the protection of the environment. The agencies are the State Department of
Health Services and the State Regional Water Quality Control Board.
The State Department of Health Services must authorize that the design and operation
of the facilities"is in compliance with Title 22 of the California Administrative Code
which regulates industries that generate hazardous waste. Their authorization of the
project is attached to the attached fact sheet. _ ™iam-v
The State Regional Water Quality Control Board establishes regional water quality
standards, issues discharge permits and monitors discharges to_insure compliance with
the water aaulity standards. Our present discharge permit is in effect into 1990 It
is also empowered to enforce the Environmental Protection Agency's water quality standards

FACT SHEET
ENCINA POWER PLANT WATER TREATMENT TANKS
San Diego Gas & Electric is requesting permission to install six
wastewater collection tanks and associated facilities at the
Encina Power Plant. The new tanks will replace the six ponds
currently being used for wastewater collection at the plant.
Above ground tanks are currently the most environmentally sound
technology for wastewater collection and temporary storage. The
tanks will allow SDG&E to comply with the Toxic Pits Act of
1984. The ponds will be closed/removed in accordance with a
"closure plan" approved by the State Department of Health
Services, and the obtaining of all other applicable State and
Regional and/or local governmental entitlements.
CURRENT PROCESS
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.
Low volume wastewater 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
-1-
result from activities like a homeowner washing a driveway,
carwashes or garages.
This material is not considered to be hazardous by legislative
definition, and concentrations are small and the threat to
public health or the environment is considered to be extremely
minimal. About 99 percent of the time, low volume wastewater
falls within limits considered by the Regional Water Quality
Control Board to be clean enough to discharge into the ocean
without treatment.
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 personnel
are not required to wear protective clothing or breathing
apparatus when handling them. The cleaned water is forwarded to
the treated water ponds.
-2-
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.
LEGISLATION
In 1984, the California State Legislature accepted Assemblyman
Katz' bill setting more stringent standards on the construction
and operation of hazardous waste impoundments.
To comply with the new law, SDG&E carefully studied two options:
relining the existing ponds or using steel tanks to hold the
water. SDG&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 hazardous waste facilities. (see
attached letter)
THE NEW TANKS AND OIL AND SOLIDS COALESCER
The installation of above ground tanks and an oil/solids
coalescer will virtually eliminate the possibility of any
potential ground water contamination. Key features of the new
system are:
-3-
-- 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.
-- 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 redundant
backup system.
-- Because the new system will make the most effective use of
the equipment and involve the addition of the oil and solids
coalescer, the amount of wastewater on site 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.
-- 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.
-4-
-- 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.
-- The tanks will range from 18 to 30 feet in height and be
constructed of steel. 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.
-- The tanks, like the larger ponds currently in place, will not
be covered. Covering the tanks would create a danger to plant
employees who must go inside them for cleaning and observation
of water levels. Additionally, covering the tanks would
necessitate the project's redesigning and increase the cost.
And, although some of the materials inside the tanks are
classified as hazardous, they pose no danger to the environment
according to the Regional Water Quality Control Board and other
regulatory agencies.
