Summary:

Pursuant to the requirements of the federal Energy Policy Act of 2005, the regulation is amended to accomplish the following: (i) require secondary containment of all new and replacement underground storage tanks (USTs) and associated piping within 1,000 feet of an existing community water system (this includes the piping distribution system) or other potable drinking water well; (ii) develop criteria for determining what tanks are ineligible for petroleum delivery, the methods for marking the tanks, providing notice to owners/operators and delivery companies that the tanks are ineligible, and reclassifying ineligible tanks as eligible; and (iii) require training for certain classes of UST operators. The goal of the amendments is to reduce the number and severity of petroleum leaks from UST systems by strengthening pollution prevention requirements and encouraging UST owners and operators to maintain compliant UST systems.

Since publication of the proposal, 9VAC25-580-125 has been modified to clarify when a deliverer is responsible for delivering to an ineligible tank, and, in 9VAC25-580-370, the requirement for certain operators to be on site within 24 hours and the time frame for retention of training records has been modified.

The full text of this new federal legislation can be found at http://www.epa.gov/oust/fedlaws/nrg05_01.htm. This action consolidates two Notices of Intended Regulatory Action: Amendment Regarding Operator Training for Owners and Operators (24:14 VA.R. 1887 March 17, 2008) and Incorporation of Requirements of Federal Energy Policy Act of 2005 (23:25 VA.R. 4100 August 20, 2007).

Summary of Public Comments and Agency's Response: A summary of comments made by the public and the agency's response may be obtained from the promulgating agency or viewed at the office of the Registrar of Regulations.

The fact finding shall be scheduled as soon as practicable after the notice, and within 10 business days in any event. Upon a finding to impose delivery prohibition, the board shall affix a tag to the fill pipe of the underground storage tank(s) prohibiting delivery, deposit, or acceptance of a petroleum product or other regulated substance.

E. When the board issues a notice of alleged violation based on an inspection or other information that provides reason to believe a UST system is not in compliance with the requirements of Part II, III, or IV of this chapter not listed in subsection B of this section, the requirements of 9VAC25-580-240 through 9VAC25-580-280, or the requirements of 9VAC25-590 (Petroleum Underground Storage Tank Financial Responsibility Requirements), and the owner or operator fails to comply with the notice of alleged violation within the time prescribed by the board, the board may proceed in accordance with subsection D of this section.

F. The board may classify all underground storage tanks containing petroleum or any other regulated substance at a facility as ineligible for delivery, deposit, or acceptance of a petroleum product or other regulated substance if one or more underground storage tanks at the facility has been classified as ineligible for more than 90 days and the ineligible underground storage tank(s) has neither been closed in accordance with 9VAC25-580-310 or 9VAC25-580-320 nor returned to compliance. The board shall provide written notice to the owner and operator pursuant to subdivision G 1 of this section that it will conduct an informal fact finding pursuant to § 2.2-4019 of the Code of Virginia to determine whether all the underground storage tanks shall be ineligible for delivery, deposit, or acceptance of a petroleum product or other regulated substance. The fact finding shall be scheduled as soon as practicable after the notice, and within 10 business days in any event.

G. Notice.

1. The board shall provide written notice of an informal fact finding to consider delivery prohibition to the owner and operator. The notice shall meet the requirements of § 2.2-4019 of the Code of Virginia. The notice shall further advise the owner and operator of the possibility of a special order pursuant to subsection I of this section.

2. The presence of the delivery prohibition tag on the fill pipe of an ineligible underground storage tank shall be sufficient notice to any person, including the owner, the operator, and product deliverers, that the underground storage tank is ineligible for delivery or deposit. The board may use other methods in addition to the delivery prohibition tag to provide notice to product deliverers.

H. An owner or operator shall notify the board in writing once an ineligible underground storage tank has been returned to compliance and provide a written report detailing all actions that have been taken to return the UST system to compliance, as well as supporting evidence such as test reports, invoices, receipts, inventory records, etc. As soon as practicable after confirming that the underground storage tank is in compliance with the requirements of this chapter or 9VAC25-590, or both, but in no event later than two business days, the board shall remove or authorize the owner or operator, in writing, to remove the delivery prohibition tag.

I. If the board determines that a violation exists that warrants the imposition of delivery prohibition, the board may further consider whether the threat posed by the violation is outweighed by the need for fuel from the underground storage tank(s) in question to meet an emergency situation or the need for availability of or access to motor fuel in any rural and remote area. If the board finds that such a condition outweighs the immediate risk of the violation, the board may defer imposition of delivery prohibition for up to 180 days. In every such case the director shall consider (i) issuing a special order under the authority of subdivision 10 of § 10.1-1186 of the Code of Virginia prescribing a prompt schedule for abating the violation and (ii) imposing a civil penalty.

J. The board may temporarily authorize an owner or operator to accept delivery into an ineligible underground storage tank(s) if such activity is necessary to test or calibrate the underground storage tank(s) or dispenser system.

K. Nothing in this section shall prevent the board or the director from exercising any other enforcement authority including, without limitation, their authority to issue emergency orders and their authority to seek injunctive relief.
