2. Find that an amendment is required to Ordinance 9279
(Specific Plan) .
ITEM EXPLANATION:
In 1971 the City Council adopted Ordinance 9279 approving a specific plan (SP-144) for SDG&E - Encina Power plant. Condition six of that approval reads as follows:
"6. All fuel storage tanks shall be recessed and used for
those oils which, upon being consumed, shall not have a sulphur content exceeding .50 percent; being that per- centage commonly associated with the term "low sulphur
fuel oil."
On March 2, 1982 the City Council approved the testing of a medium sulfur fuel at Encina. The purpose of the test was
to determine if higher sulfur fuel could be burned along with
natural gas without increasing air pollution.
The test was completed and analyzed by the County Air Pollutif
Control District (APCD). On March 7, 1983 the District found
that the test burn successfully met the emission standards fo
allowable air pollution.
SDG&E has requested the City Council to find that the use of higher sulfur fuel is consistent with Condition six of Ordina
9279.
The key issue is to interpret the meaning of Condition six. SDG&E's position is that the City intended to control what co out of the stack and not the fuel used. It is immaterial wha
limits, APCD has ruled that the test emissions comply with R
62. Therefore, the Council could find that the fuel "upon be
consumed" does not exceed 0.5% sulfur.
If the Council believes that Ordinance 9279 should be amended
then it will be necessary to hold public hearings before the Planning Commission and Council to change Condition six in

The attached summary report provides some background and perspective on the Encina Power Plant operation and its effect on the Carlsbad area. It is our charter to not only
provide a safe, adequate, and reliable source of electrical
energy, but also our responsibility to provide that service at the most reasonable cost. Therefore, SDG&E encourages you, on the behalf of all of San Diego County, to approve the
controlled use of a medium sulfur fuel oil at Encina. The
community at large will benefit from reduced electric rates
without Carlsbad paying any price in terms of lower air quality.
Sincerely,

mDIUM SULFUR FUEL TEST
Summary Report & Perspective
San Diego County Air Quality
Many people have moved to San Diego County, and Carlsk in particular because of its relatively clean air. It is a re-
source that is vitally important to the Carlsbad residents and
should be protected. Some longtime residents may have observed some periodic deterioration of their air over the last decade or so, but recent trends are toward improvement.
Historically, ambient air quality health standards ha1
been exceeded in San Diego County for ozone, nitrogen dioxide,
carbon monoxide, and particulate matter. The first three of the
are primarily motor vehicle generated, while the particulate mat
ter is usually from natural sources. Levels of sulfur dioxide,
which is emitted mainly by industrial sources such as power plan
havenever been a problem and continue to remain far below (at approximately 1/10 or less of) the national standard. Improve- ments in motor vehicle emissions control, and the wide-ranging
and effective activities of the San Diego County Air Pollution Control District have reduced the levels of these pollutants
over the last few years. San Diego County can again boast Of
good air quality. Only the ozone and particulate matter stan- dards are still exceeded now, and the particulate matter standard will be changed in recognition of the natural blowing dust and sand.
The remaining problem, and that which most affects Carlsbad, is the transport of air pollutants down the coast from
the Los Angeles/Orange County area. moves the pollution out over the ocean from L.A. and then back in over the San Diego North County coast is well understood and predictable. back to sources outside San Diego County. Hopefully, implementa- tion of motor vehicle inspection and maintenance programs, both .
San Diego and the counties to the north, will reduce the remainii problem.
The weather pattern that

The San Diego APCD, in its 1982 revision to the County
air quality management plan, predicts continued imyrovement.
Figure 1, taken from the APCD plan, shows Carlsbad to continue
to remain centered in the cleanest area in San Diego County all
the way out to the year 2000. The existence of the Encina Power
Plant does not now, nor is it likely to have a significant im-
pact on air quality in the future.

Table 1, also from the APCD plan, is a summary of the
emissions inventory for San Diego County. The significance of
the figures is the relatively small contribution of power plant
(Boilers) to the overall inventory. Although power plants are
the major source of sulfur emissions, the actual amount and its
impact on the environment are very small.
Power Plant Emissions
The Encina Power Plant has little effect on the air
quality of Carlsbad, with the only exception being a rare, oc- casional increased emission of carbon particulates. This
occurence is very unusual, however, and when caused by a mal- function it is reported to the APCD and quickly corrected.
knissions of this nature are not representative of normal
operation.

Medium Sulfur Fuel Test Background
SDG&E power plants. However, in the early 1970's, it became scarce, and fuel oil was adopted as an increasingly used backup
fuel. used in other states, the San Diego APCD and SDG&E agreed to
limit the sulfur level in oil used in the County to 0.5% or its
equivalent. Until recently, the sulfur content had little im-
pact on the fuel cost.

become more dependent upon the sulfur content, and relatively
Through discussions with the APCD, it was agreed that if such a "medium sulfur fuel" could be used concurrently with
natural gas, which contains no sulfur, then the resulting : emissions should be "equivalent" to that which would have re- sulted from the use of 0.5€ sulfur fuel. Such an averaging
concept is allowed under APCD rules and regulations.
Carlsbad Specific Plan (SP-1441, which was adopted about the same time as the APCD fuel sulfur limitation, also contains a provision limiting the sulfur stored in the tanks,
such that when it is burned, is no greater than 0.5%.
Regrettably, the additional phrase "or its equivalent" was
inadvertantly omitted. However, in a memorandum from James C. Hagaman, Planning Director, to Frank Aleshire dated
February 19, 1982, a test burn of the medium sulfur fuel was
determined to be consistent with SP-144.
Therefore, in early 1982, SDG&E requested permission from both the APCD and the City of Carlsbad to perform a short test of a medium sulfur fuel in a couple units of the Encina
.Power. Plant. It was desirable to use the Encina plant for the -testbecause of its single stack which could serve the purpose of combining the emissions from all of the units together, both
those on natural gas, and those on the medium sulfur oil.
the APCD and SDG&E wanted to demonstrate that the plant operato: were able to maintain the equivalent emission level. This mean that the total sulfur emissions, with the medium sulfur oil and natural gas, were no greater than the sulfur that would have been emitted if only 0.5% sulfur oil was used. It is establish6
that the use of 0.5% sulfur oil, even at maximum capacity, did
not harm the environment.

oil can be used without a detrimental effect on the boilers.
The test data show that the use of medium sulfur fuel oil, in conjunction with the proper quantity of natural gas,
causes no more air emissions than has been historically emitted using the 0.5% sulfur oil only. All emission limits were com-
plied with and no degradation of the Carlsbad air quality occurred.
Permission Requested for Regular Use of Medium Sulfur Fuel
to use medium sulfur fuel oil on a regular basis in the Encina
Power Plant. If SP-144 cannot now be interpreted to allow this, the addition of the phrase "or its equivalent" may be the easie5
solution. This would make Carlsbad's SP-144 essentially the sar as the APCD equivalency provision presently in their Rule. Sucl permission would give SDG&E the flexibility to utilize a less expensive fuel without a detrimental effect on the environment.
To guarantee this protection of Carlsbad's air quality, SDG&E will place a permanent continuous sulfur dioxide monitor in the
combined stack, as required for the test.

SDG&E has formally requested similar permission from the APCD to use medium sulfur fuel oil at Encina on a regular basis, based upon the success of the test. Such authority from
the APCD is expected very shortly.
Conclusions
It is the Charter of SDG&E to not only provide a safe, adequate, and reliable source of electrical energy, but also its responsibility to provide that service at the most reasonable
cost. The purpose of the medium sulfur fuel test was to demon- strate that the community will benefit by utilizing lower cost oil without the City of Carlsbad paying a price in increased

consistent with the intent and Durpose of Condition No.6 of Ordinance No.9279 (SP-144).
That condition is:
"All fuel storage tanks shall be recessed and used for those oil
which, upon being consumed, shall not have a sulfur content excel in9 0.5%.
Therefore, the issue is not the sulfur content of the fuel when
it is stored, but the resulting sulfur content of the fuel, as determined by the power plant emissions.
The utilization of 0.75% sulfur fuel in units 4 & 5 in conjunctic with natural gas in some of the other units does not violate the
tent of Condition 6. Sulfur content of consumed fuel is determir by measuring emissions. The APCD has determined that SDG&E can t
0.75% fuel in some units and not exceed the sulfur limit of the
existing rules & regulations for the overall power plant.
The City of Carlsbad can make an administrative determination of
consistency with Ord.No.9279 (SP-144) because:
O The APCD is the lead agency for permits involving the
-75% can be utilized at Zncina in compliance with the
existing rules & regulations.
utilization of fuel oil. The APCD has determined that
O Since the APCD is a Fublic agency designated for the
protection of the environment, this action is not
subject to an Environmental Impact Report. Extensive tests and additional conditions imposed by the APCD
ensure compliance with air quality standards imposed
by the City in Ord.9279 and subsequent Ord.9456,
which amended Ord.9279.
O Condition 6 of Ord.9279 is based on Rule 62 of APCD
Regs. This was determined by the City in February, 1982.
O The Council found that the intent of SP-144 (Ord.9279)
was met for the test burn and based on input from APCD
an amendment to the Specific Plan was not necessary at that time.
' Ordinance 9456 (April 1976) relys heavily on APCD regulation of emissions. control in Carlsbad indicates that the City defers to the APCD (lead agency) on air quality issues.

O The APCD has again determined that Rule 62 of their
regulations would not be violated by allowing the use
of -75% sulfur fiPel.
O The City can deternine consistency with Condition 6 of
Ord.9279 administratively. This precedent has been
established with the administrative determination that
allowed the construction of Cannon Sub at Encina.
(See Staff Report to Planning Comnission, date June 23,
1982).
Ord.9279 designates the Plannhg Director as the enforcing officer of SP-144,

The Planning Director has already determined that
Condition 6 is based on APCD Rule 62 and the APCD has
determined that we comply with Rule 62.
