Regulatory Roles

• California Air Resources Board
• Vapor recovery rulemaking
• Certifies Phase I and Phase II systems
• State Water Resources Control Board
• USTs, Overfill Prevention, Secondary
  Containment
• Develops regulations enforced by CUPAs
• Local Air Pollution Control Districts
• Permit GDFs and enforce vapor recovery rules

EVR Applicability

• Phase I and Phase II systems at gasoline
  dispensing facilities with underground storage
  tanks (USTs)
• New and existing facilities
• EVR does not require VR systems if not already
  required by district rule
• EVR for ASTs is under development
  (www.arb.ca.gov/vapor/ast/ast.htm)

7
Partial EVR Exemption for Districts in
Attainment with State Ozone Standards

• Exempts existing sites from all EVR modules
  except ORVR compatibility
• ORVR compatibility required to minimize benzene
  exposure
• New facilities and facilities with major
  modifications must comply with EVR

9
Recent Change in State Ozone Standards

• More stringent state ozone standard approved by
  ARB at April 2005 meeting
• Still going through rulemaking process
• May change district attainment status in the next
  year
• CP-201 section 2.4.4 allows 4 years to comply if
  district reclassified

10
New vs. Existing GDF

• EVR standards phased in over several years with
  multiple deadlines
• New facilities need to meet all operative EVR
  standards
• Existing facilities have up to four years after
  the effective date of the standard to comply
• Major Modifications change status from
  existing facility to new facility and trigger
  operative EVR requirements

11
Phase I Major Modification
Modification of the Phase I system that involves
the addition, replacement, or removal of an
underground storage tank, or modification that
causes the tank top to be unburied, is considered
a major modification of the Phase I system.
12
Phase II Major Modification

• Addition, replacement or removal of 50 percent or
  more of the buried vapor piping, or the
  replacement of dispensers, is considered a major
  modification of the Phase II system. The
  replacement of a dispenser is not a major
  modification when the replacement is occasioned
  by end user damage to a dispenser. Phase II
  system upgrades to make the systems ORVR
  compatible do not constitute a major
  modification. Phase II system upgrades to comply
  with the under-dispenser containment requirement
  (CCR, Title 23, section 2636(h)(1)) initiated
  before January 1, 2004 do not constitute a major
  modification. Modifications to dispensers may
  require use of unihose configurations as
  described in CP-201 section 4.11.

Unihose Requirement

• There shall be only one hose and nozzle for
  dispensing gasoline on each side of a
  multi-product dispenser (MPD). This shall not
  apply to facilities installed prior to April 1,
  2003 unless the facility replaces more than 50
  percent of the dispensers. Facility modifications
  that meet the definition of major modification
  for a Phase II system in D-200 trigger the
  unihose requirement as the facility is considered
  a new installation. Exception dispensers which
  must be replaced due to damage resulting from an
  accident or vandalism may be replaced with the
  previously installed type of dispenser.

What ISD doesn't do

• Exempt station owners from receiving a notice of
  violation
• Identify single events that are out of the
  acceptable limits
• Identify borderline failures
• Exempt station owners from annual compliance
  testing

42
ARB ISD Enforcement Policy

• ISD output not currently appropriate for
  enforcement
• No response by GDF operator to ISD failure signal
  is enforceable

43
18 Month ISD Evaluation

• Examine the capital cost impacts of ISD on
  smaller throughput GDFs
• Determine whether performance of field ISD
  systems is similar to performance of the system
  tested in certification
