SECTION 252:616-5-1. Site and system

(a)   Location and construction. Locate and construct industrial wastewater systems in a manner which will minimize adverse impacts to waters of the State and the environment. Do not locate in floodways. If located in a flood plain, the crest elevation of dikes must be at least one foot above the 100-year flood elevation and the DEQ may require additional erosion controls.

(b)   Separation distances. The following separation distances are required:

(1)   Tank systems and surface impoundments must be separated at least 50 feet from private water wells (100 feet if the ground slopes towards the well) or surface water supplies, and 300 feet from public water supply wells. Separate tank systems by 5 feet and surface impoundments by 10 feet from property lines.

(2)   Land application must not occur:

(A)   in designated wellhead delineation areas of private or public water supplies;

(B)   within one-half mile of an outstanding resource water or its tributaries or a high quality water as identified in Appendix A of the Oklahoma Water Quality Standards;

(C)   within one-quarter mile of a water listed in Appendix B of the Oklahoma Water Quality Standards;

(D)   within 250 feet of a well used for a potable water supply or within 100 feet of any surface water of the state not otherwise referenced in (3) or (4) of this paragraph; or

(E)   within two feet of the highest measured groundwater elevation at the site.

(c)   Site security. Restrict access to industrial wastewater systems and land application sites by fences, secured gates or other reasonable means. Post a sign listing the name of the facility operator, an emergency telephone number and the DEQ permit number.

(d)   Site protection. Do not allow wastewater to escape, unless specifically authorized in the permit through lateral lines or through a discharge permit. Construct and maintain facilities to prevent contamination of the surrounding soil and ground water.

(e)   System protection. Protect tank systems from vehicular traffic, and prevent vehicular traffic over lateral fields. Provide soil, gravel or splash pads to protect surface impoundment liners during routine operation and maintenance.

(f)   Purpose. All industrial wastewater systems must be designed for a specific treatment purpose (such as settling, biological degradation, beneficial reuse or final disposal), and shall be maintained and operated to produce optimum treatment results.

(g)   Site specific. The DEQ may impose specific construction, operation and maintenance requirements based on wastewater type and environmental compatibility, on a case-by-case basis.
