SUBJECT: AIR QUALITY MONITORING EQUIPMENT AS REQUIRED FOR
ENCINA STACK MODIFICATION PROJECT.
STAT�'• EIMENT OF THE MAITER
WCity Council Ordinance #9456 required the Air Pollution Control Officer
and City Council to approve the type and location of air quality monitoring M
equipment to measure emissions from the•Encina Power Plant. The Air
Pot=lution Control Officer has proposed monitoring sites and equipment which
would measure the maximum impact of the plant's operation, both before and
after the initiation of Unit #5. With the Council's concurrence, these
moni-toring stations should be operative by March 1.

MEMORANDUM
February 15, 1977
TO: CITY COUNCIL
FROM: PLANNING DEPARTMENT
SUBJECT: AIR QUALITY MONITORING EQUIPMENT PER THE
REQUIREMENTS OF ORDINANCE NO. 9456
(ENCINA POWER PLANT STACK MODIFICATION)
BACKGROUND:
'City Council Ordinance No. 9456 (see attached excerpt) requires
that San Diego Gas and Electric install air quality monitoring,
equipment as a condition of approval for the Encina Power Plant
stack modification. The condition states that the type and loca-
tion of the equipment is subject to the approval of the Air Pollution
Control Officer and the City Council. The equipment';was
to be operative six months after the effective date of the Ordinance
(July 20, 1976).
The six=month deadline has not been met because of the time involved
in selecting equipment, surveying potential sites and gaining
i property owner permission for use of those sites. Staff would like
to point out that these delays in no way reflect a lack of diligence
on the part of the applicant.
MONITORING_SITES:
i
San Diego Gas and Electric has secured property for installation
of monitoring stations at these three sites recommended by -the
APCD (see Exhibit B):
Site #1_: is at a reservoir site located on SDG&E property southeast
of-TFe proposed HUB Park. The sit& is at an approximate elevation
of 200 feet. You will note that in a letter to the City dated
December 24, 1976, the APCD had recommended that Site #1 be located
at Evans Point (see Exhibit 8); however, this site could not be
secured, so the APCD has recommended the reservoir location
instead. APCD officials believe that this location is suitable
for measuring the localized impact of the power plant.
Site #2: is located within the Oceanside City limits on San
ram ncisco Peak, adjacent to a water tank: This site is
approximately 4.8 miles northeast of the Encina Plant. According
to the Air Pollution Control District, this general area is pro-
jected to be the location of maximum impact of pollutants emitted
from the modified facility under 'worst case' meteorological condi-
tions. This site is at an elevation of approximately 540 feet.
Site #3: is located at another water tank site near the intersection
ofEncinitas Road (extension of Palomar Airport Road) and Rancho
Santa Fe Road, in the unincorporated area midway -between Carlsbad's
and San Marcos' City boundaries. This site is about 7.1 miles east
<
of the power plant, at an elevation of 700 feet. The APCD's pro-
jections indicate that, because of prevailing wind conditions and
distance downwind from the plant, this area will experience the
most predominant impact from the expanded power plant.
It should be noted that the APCD has recommended monitoring sites
a
which would record maximum impacts resulting from the Power
Plan is operation. Since the monitoring sites were required to
specifically measure emissions from the Encina Power Pl-ant, loca-
tion of the monitoring stations in lesser impact areas would be
counterproductive. The installation of the equipment prior to
utilization of Unit 5 and of the single stack will enable the APCD
to verify the air quality projections which have been made.
4
MONITORING -EQUIPMENT:
'
The APCD has provided a list of equipment proposed for installation
at each of the monitoring sites. (See Exhibit A.) This equipment
wil-1 be capable of monitoring all significant pollutants emitted
by the Power Plant. As noted in the APCD's letter, all equipment
.
is "state of the art" and satisfies state and federal monitoring
requirements.
t
EQUIPMENT. -COSTS:
The equipment costs have been secured from San Diego Gas and
Electric, and are within the limits set by Ordinance No. 9456.
IMPLEMENTATION:
i
The APCD has indicated that monitoring at sites #2 and #3 can be
operative by mid -February, and Site #1 can be operative shortly
thereafter.
RECOMMENDATION:
That the City Council concur with the APCD's recommendations for
s
air quality monitoring sites and equipment, as required by
Condition 14(D) of Ordinance No. 9456.

Dear Mr. Plender:
As a condition of the Special Use Permit granted to San Diego Gas & Electric
,by the*Carlsbad City Council for construction of a 400-foot stack at the
Encina Power Plant, SDG&E was required to provide three monitoring stations
downwind from the facility. The San Diego Air Pollution Control District
has•surveyed the area and selected sites appropriate for assessment of the
air quality impact of the existing and proposed facilities (see map
attached).
These sites were selected based on area of projected maximum impact,
exposure, and availability of the site and services.
Site #1 is located at Evans Point on the property of ter. Allan 0. Kelly.
T�tis site was selected primarily to determine the localized impact of the
existing facility. The site is at an approximate elevation of 300 feet at
a distance of 2.2 miles downwind with excellent exposure.
Site 112. is located at San Francisco Peak approximately 4.8 miles northeast
of the facility on local water district property. This general area is
projected to be the location of maximum impact of the pollutants emitted
from the modified facility under "worst case" meteorological conditions.
Site #3 is located approximately 7.1 miles east of the power plant in the
vicinity of Encinitas Road and Rancho Santa Fe Boulevard on the western
edge of San Marcos and at an elevation of 700 feet. Projections indicate
that this area will experience the most predominant impact from the new
facility due to the prevailing westerly wind and distance downwind.

Re: Source i•;onitoring Encina "S",
Previous Communication December 24, 1976.
In my previous communication, I inadvertently omitted a list of equipment
to be installed and operated by the District at each of the proposed monitoring
sites. 'she equipment listed in the enclosed table is considered "state of ti.e
art" and satisfies all state and federal requirements for equivalency with
established reference methods.
If you have any questions on the equipment selection, siting or measurement
f techniques, please refer them to Michael Poley at S6S-3947
