Hearing to Consider Proposed Revisions to the Air Resources Board
Suggested Vapor Recovery Rules.
RECOMMENDATION
Adopt Resolution 77-56 which revises the Air Resources Board's
Suggested Vapor Recovery Rules as shown in Exhibit I to this
report.
SUMMARY
Since the Air Resources Board (ARB) approved its "Suggested Vapor
Recovery Rules" dated April 1975, there have been substantial
advances in vapor recovery technology. Recent data indicate that
more effective vapor recovery rules are appropriate given the
facts that California needs all the hydrocarbon control possible
to achieve and maintain ambient air quality standards and that
vapor recovery is one of the most cost effective hydrocarbon
control strategies available.
Among the proposed revisions to the model vapor recovery rules is
an increase in the vapor collection efficiency from 90 percent to
95 percent for terminals, certain bulk plants and the fueling of
passenger cars at most gasoline stations.
Section 41954 of the Health and Safety Code requires that, on or
after July 1, 1976, all gasoline stations without vapor recovery
may only install an ARB certified vapor recovery system. The
South Coast Air Quality Management District Regulations require
that service stations in the District must have ARB certified
systems installed and operating within six months of the time
when certified systems are available. The first system capable
of meeting all requirements of the ARB was certified on July 2,
1977. The staff's understanding of the intent of the State
Implementation Plan is that certified systems are to be installed
12 months after they are available.
The potential suppliers of certifiable systems have indicated to
the staff that they cannot make a sufficient number of systems
available in time for statewide compliance to be achieved in the
next 12 months. A compliance schedule is suggested for adoption
by the Board which requires the installation of vapor recovery
systems on facilities with the highest volume throughput first.
A schedule is also proposed for the upgrading of vapor recovery
systems which were installed prior to the Legislative prohibition
on the use of systems not certified by ARB. This schedule for
system upgrading will eliminate the serious efficiency and safety
problems which plague the systems which are in wide spread use in
the Bay Area.
Implementation of the schedule proposed by the staff would cause
a reduction in hydrocarbon emissions from vehicle fueling
operations of 56 tons per day in the South Coast Basin by 1981.
ITEM NO.: 77-25-2
Public Hearing to Consider Proposed Additions to the Rules and
Regulations of the South Coast Air Quality Management District
for Controlling Emissions of Sulfur Oxides from Petroleum Coke
Calcining Facilities.
RECOMMENDATION
Adopt Resolution No. 77-55, thereby adding Rule No. 1119
"Emissions from Petroleum Coke Calcining Facilities" to
Regulation IV of the Rules and Regulations of the South Coast Air
Quality Management District as shown in Exhibit A.
SUMMARY
Sulfur dioxide and sulfur trioxide, emitted in the operation of
petroleum coke calcining in the South Cost Air Shed, are
converted in the atmosphere to sulfate particles and contribute
to violations of state ambient air quality standards. These
sulfur compounds also contribute substantial to the suspended
particulate matter burden of the atmosphere, and they are a
significant contributor to visibility reduction in the South
Coast Air Shed.
Current petroleum coke calcining operations in the Air Shed are
estimated to result in sulfur oxides emissions of about 20 tons
per day. The source of these emissions is the combustion of
sulfur contained in petroleum coke in concentrations of about one
to two percent by weight.
To reduce these emissions, the staff is proposing a process
weight rule to limit the emissions of sulfur oxides from
petroleum coke calcining facilities to 750 grams of sulfur oxides
(expressed as sulfur dioxide) per metric ton of coke charged (1.5
pounds per short ton). This limit corresponds to a sulfur oxides
reduction from uncontrolled emissions of about 90 percent. Flue
gas desulfurization will probably be required to achieve the
necessary reductions. In addition, the rule establishes a
procedure for assuring final compliance by January 1, 1981.
