Gasoline Dispensing Facility - Questions
What is an Aboveground Gasoline Storage Tank or AST?
Answer: An AST is a gasoline storage tank that is intended for fixed installations, without backfill, that is located above or below grade. ASTs are commonly classified as either "single-wall" or "protected". Single-wall ASTs are constructed with a primary (single) wall typically made of steel. Protected ASTs are constructed with a primary (inner) tank encased by a secondary (outer) tank, with a layer of insulating material (at least three inches thick) between the primary and secondary walls. The insulating material is usually lightweight concrete or a similar material.
Are gasoline dispensing facilities equipped with ASTs located in "attainment areas" for the Federal standard for ozone exempted from SLC requirements?
Answer: Yes, existing ASTs in Federal ozone attainment areas are not required to comply with SLC, but these ASTs must keep their pre-EVR Phase I and Phase II equipment. Any new AST installed after April 1, 2009, regardless of whether it is in an attainment area or not, must comply with SLC requirements. See responses to questions 3.3 and 3.4 for Phase II requirements for new AST installations.
Who is subject to Phase II EVR?
Answer: No new or existing ASTs are subject to Phase II EVR as of April 1, 2014. Phase II EVR requirements will apply once a Phase II system is certified for ASTs. Existing ASTs subject to Phase II EVR will have four years from the effective date to comply. The effective date is the date when the first Phase II EVR system for ASTs is certified. A Phase II EVR system is expected to be certified sometime in 2014.
