Current through Register Vol. 43, No. 02, November 27, 2024

Section 335-13-15-.03 - Location Restrictions

(1) Placement above the uppermost aquifer.

(a) New CCR landfills, existing and new CCR surface impoundments, and all lateral expansions of CCR units must be constructed with a base that is located no less than 1.52 meters (five feet) above the uppermost aquifer as determined by the following procedures:

1. The site hydrogeology shall be established to the upper most aquifer and subsequent interconnecting aquifers. The hydrogeological evaluation for a specific site must be performed by a firm or individual having expertise in hydrogeology. The hydrogeological evaluation shall require a minimum of three exploration borings to include sampling and geologic logging and completion of these borings as piezometers.

2. Two groundwater measurements shall be taken during each of the three consecutive months of February, March, and April with no two measurements taken within any twelve day period, or as otherwise approved by the Department.

3. From the hydrogeological evaluation and groundwater measurements, the subsequent establishment of the first saturation zone, the uppermost aquifer and subsequent underlying and interconnected aquifers, piezometer measuring point elevations, water table elevations and an estimate of groundwater flow direction and rate will be required.

4. Based on the groundwater measurements, the owner or operator of a new CCR unit or any lateral expansion of a CCR unit shall design the CCR unit so that the bottom base is five feet above the uppermost aquifer.

5. When the geological and hydrological data so indicate, the Department may specify greater separation distances to protect groundwater.

6. When the geological and hydrological data so indicate, the Department may allow engineering controls to remove, divert, drain, or otherwise modify zones of saturation above the uppermost aquifer.

(b) The owner or operator must demonstrate by the dates specified in 335-13-15-.03(1) (d) that the CCR unit meets the minimum requirements for placement above the uppermost aquifer.

(c) The owner or operator of the CCR unit must obtain a certification from a qualified professional engineer stating that the demonstration meets the requirements of 335-13-15-.03(1) (a).

(d) The owner or operator of the CCR unit must complete the demonstration required by 335-13-15-.03(1) (a) by the date specified in either 335-13-15-.03(1)(d)1. or 2.

1. For an existing CCR surface impoundment, the owner or operator must complete the demonstration no later than October 17, 2018.

2. For a new CCR landfill, new CCR surface impoundment, or any lateral expansion of a CCR unit, the owner or operator must complete the demonstration no later than the date of initial receipt of CCR in the CCR unit.

3. The owner or operator has completed the demonstration required by 335-13-15-.03(1) (a) when the demonstration is placed in the facility's operating record as required by 335-13-15-.08(1) (e).

1. Where applicable under section 404 of the Clean Water Act or applicable state wetlands laws, a clear and objective rebuttal of the presumption that an alternative to the CCR unit is reasonably available that does not involve wetlands.

2. The construction and operation of the CCR unit will not cause or contribute to any of the following:

(i) A violation of any applicable state or federal water quality standard;

(ii) A violation of any applicable toxic effluent standard or prohibition under section 307 of the Clean Water Act;

(iii) Jeopardize the continued existence of endangered or threatened species or result in the destruction or adverse modification of a critical habitat, protected under the Endangered Species Act of 1973; and

(iv) A violation of any requirement under the Marine Protection, Research, and Sanctuaries Act of 1972 for the protection of a marine sanctuary.

3. The CCR unit will not cause or contribute to significant degradation of wetlands by addressing all of the following factors:

(i) Erosion, stability, and migration potential of native wetland soils, muds and deposits used to support the CCR unit;

(ii) Erosion, stability, and migration potential of dredged and fill materials used to support the CCR unit;

(iii) The volume and chemical nature of the CCR;
