Affected: IC 14-37
Sec. 2.
(a) This section establishes requirements for the operation of tank battery facilities.(b) Each tank battery facility shall have a legible sign posted in a conspicuous place on or near the crude oil or produced water storage tanks. The sign shall be a size and shape that is easily read from a distance of twenty (20) feet showing the following information:(1) The owner or operator name.(2) The name of the lease or production unit.(3) The facility registration number assigned by the division.(4) An emergency telephone number.(5) The section, township, range, and county of the facility location.(c) All tank battery facilities shall be surrounded by a secondary containment structure meeting the following requirements:(1) The capacity of the secondary containment structure shall be designed, constructed, and maintained to contain at least one hundred ten percent (110%) of the capacity of: (A) the largest single tank; or(B) conjoined tanks equipped with manifolds configured so that the fluid level in each tank equalizes as fluids are added to or withdrawn from the conjoined tanks; located within the secondary containment structure.
(2) Natural or manmade material used for construction and lining of the secondary containment structure shall be:(A) sufficiently impervious to contain fluids; and(B) resistant to corrosion.(3) Earthen materials used to construct secondary containment structures shall be stabilized and protected from erosion.(4) Vegetation within or surrounding a secondary containment structure shall not pose a fire hazard.(5) The interior of a secondary containment structure shall be kept free of excessive vegetation, general oilfield waste, or any flammable material.(6) Accumulated storm water inside the secondary containment structure shall be removed within seventy-two (72) hours of accumulation.(7) All valves and fittings on storage tanks and other processing vessels shall be operated and maintained to prevent discharges or leaks of produced fluids into the secondary containment structure.(8) Except as authorized under subsection (d), pipes, conduits, or other drain lines for the purpose of draining accumulated storm water shall not pass through a wall of the secondary containment structure.(9) The discharge or drainage of storm water or other accumulated fluids to areas outside of the containment dike is prohibited unless authorized under subsection (d).(d) An owner or operator may be authorized to install a drain line through the wall of the secondary containment structure for the sole purpose of draining uncontaminated storm water as follows: (1) The owner or operator shall file an affidavit certifying that:(A) the tank battery facility has been constructed in accordance with subsection (c); and(B) a spill prevention, control, and countermeasure plan (also known as an SPCC Plan) for the tank battery facility has been prepared according to the requirements of 40 CFR 112.9.(2) The owner or operator shall submit a plan identifying:(A) procedures the owner or operator will use to ensure that discharges of storm water meet the requirements of subsection (f); and(B) the location of the SPCC Plan.(e) Upon finding that the tank battery facility and plan meet the requirements of this section, and that the operator has satisfactorily demonstrated that discharges of uncontaminated storm water from the tank battery facility will be managed in accordance with this subsection, the division director shall issue a written authorization to install a drain line through the wall of the secondary containment structure for the discharge of uncontaminated storm water.(f) No discharge of uncontaminated storm water from the secondary containment structure is permitted unless written authorization is obtained from the division director. Authorization will be granted only if all of the following conditions are met: (1) The total dissolved solids content of a representative sample of the fluid is less than seven hundred fifty (750) milligrams per liter.(2) There must be no visible evidence of hydrocarbons or a visible sheen present on the surface of the water before discharge.(3) The discharge shall take place only during daylight hours.(4) The owner, operator, or authorized representative shall be present at all times to witness the discharge of the storm water as the drain line valve is open.(5) The owner or operator shall maintain a written record of each storm water discharge indicating: (A) the facility registration number;(B) the volume of storm water discharged;(C) the total dissolved solids content;(D) the presence of any hydrocarbons or visible sheen; and(E) the date and time of the discharge. The record shall be retained and available for inspection upon request from the division director or the oil and gas inspector for six (6) months after the discharge.
(6) The drain line shall have a valve installed that:(A) shall remain closed when not in use; and(B) shall be capped or otherwise secured to protect against vandalism and unauthorized or accidental discharges.(7) A permanent sign shall be placed within five (5) feet of the drain pipe discharge that identifies: (A) the owner or operator name; and(B) the storm water discharge authorization number assigned by the division for the facility.(g) Storage tanks, separators, or other processing vessels containing produced fluids shall be kept in good repair and free from leaks. Leaking tanks or vessels shall be promptly taken out of service and repaired.(h) Failure to comply with the provisions of this rule may result in the withdrawal of the authorization to discharge uncontaminated storm water under this subsection.Natural Resources Commission; 312 IAC 29-24-2; filed 12/1/2017, 10:35 a.m.: 20171227-IR-312160230FRAReadopted filed 1/17/2023, 1:53 p.m.: 20230215-IR-312220328RFA
