GENERAL § 245.601. Purpose.
This subchapter establishes a simplified program of technical standards and requirements for small aboveground storage tanks not exceeding 21,000 gallons capacity and regulated under the act. Regulated aboveground storage tanks are defined in § 245.1 (relating to definitions).
§ 245.602. Scope.
The standards and requirements established in this subchapter shall be applied through the use of appropriate current codes of practice developed by Nationally recognized associations such as, but not limited to, those referenced in § 245.604 (relating to referenced organizations) and through the use of manufacturer's specifications and sound engineering practices. This subchapter is not intended to supersede other State and Federal regulations or jurisdictional requirements when they are more restrictive than the requirements in this part. For certain types of tanks this subchapter may make reference to the requirements for aboveground storage tanks in Subchapter F (relating to technical standards for aboveground storage tanks and facilities).
§ 245.603. General storage tank facility requirements.
(a) The owner/operator of aboveground storage tank facilities with an aggregate aboveground storage capacity greater than 21,000 gallons shall develop and adhere to a Spill Prevention Response Plan (Plan) which addresses the requirements described in Chapter 9 of the act (35 P. S. §§ 6021.901--6021.904). The Plan shall be provided to the Department and updated as necessary. A current copy of the Plan shall be readily available at the storage tank facility at all times.
(b) The owner/operator of aboveground storage tank facilities is responsible to assure that appropriate security measures and procedures based on the facility location are established and implemented to protect the environment and the public. These security measures may include, but are not limited to, fencing, lighting, access control, locked entrances and securing of valves, drains and dispensers.
