§ 1115.09. Storage Tanks and Pipelines.

No Above-Ground or Underground Storage Tank, or pipeline which contains or has contained in the past, a Regulated Substance shall be used in Wellfield Protection Area I or Wellfield Protection Area II without the approval of the Director, which approval shall be in accordance with the standards established by federal, state and local laws, regulations or orders. The Director shall determine whether the tanks or pipelines meet these standards and satisfy the requirements of subsections (a), (b), (c), (d), (e), and (f) below and shall make such determination within sixty (60) days of the submission of a certificate to him. If the Director does not act within sixty (60) days of submission of the certification, the tanks or pipelines shall be deemed denied. A registered professional engineer shall certify that all tank and pipeline systems are in compliance with applicable federal and/or state regulations governing such tank and pipeline systems which system shall include:

(a)

Adequate facilities to monitor and prevent Regulated Substances from leaching into the subsurfaces and impacting the ground water quality.

(b)

Single-walled Above-Ground Storage Tanks must be placed within a containment berm constructed to retain two hundred (200) percent of the volume of the Regulated Substance contained in the tanks. The Director may authorize less than two hundred (200) percent containment for single-walled tanks so long as engineering controls are in place to protect the ground water to the Director's satisfaction.

(c)

Double-walled Above-Ground Storage Tanks can be used without additional secondary containment provided that interstitial monitoring and/or other leak prevention technologies are provided.

(d)

Underground Storage Tanks and associated piping must be of double-walled construction and incorporate leak detection and spill prevention technologies.

(e)

Underground pipelines which carry Regulated Substances must be of double-walled construction and have leak prevention technologies.

(f)

Fifty-Five (55) Gallon Drums containing Regulated Substances shall be stored in a covered area and placed in a containment berm having the capacity to contain one hundred (100) percent of the volume of the drums. The Director may authorize less than one hundred (100) percent containment for Fifty-Five (55) Gallon Drums so long as engineering controls are in place to protect the ground water to the Director's satisfaction.

The engineering plans shall show the location of all storage tanks, pipelines, and Fifty-Five (55) Gallon Drums used for Regulated Substances, and how the storage tanks, pipelines, and Fifty-Five (55) Gallon Drums will be developed to contain Spills and prevent ground water contamination. These materials shall be contained in an Environmental Audit to be provided pursuant to Section 1115.08(E) hereof or in a Request to Use Additional Regulated Substances pursuant to Section 1115.08(G) hereof.

All storage tanks, pipelines, and Fifty-Five (55) Gallon Drums located within the Wellfield Protection Area , which contain or have contained a Regulated Substance, must be in compliance with this section, or removed within one (1) year of the effective date of this chapter or the Director approving changes to or creating a Wellfield Protection Area boundary.
