La. Admin. Code tit. 33 § V-2703

Current through Register Vol. 50, No. 6, June 20, 2024

Section V-2703 - Design and Operating Requirements

A. The owner or operator must design, construct, operate and maintain the unit to maximize the degradation, transformation, and immobilization of hazardous constituents in the treatment zone. The owner or operator must design, construct, operate, and maintain the unit in accordance with all design and operating conditions that were used in the treatment demonstration under LAC 33:V.2707. At a minimum, the administrative authority will specify the following in the facility permit:

1. the rate and method of waste application to the treatment zone;

2. measures to control soil pH;

3. measures to enhance microbial or chemical reactions (e.g., fertilization, tilling); and

4. measures to control the moisture content of the treatment zone.

B. The owner or operator must design, construct, operate, and maintain the treatment zone to minimize run-off of hazardous constituents during the active life of the land treatment unit.

C. The owner or operator must design, construct, operate, and maintain a run-on control system capable of preventing flow onto the treatment zone during peak discharge from at least a 24-hour, 25-year storm.

D. The owner or operator must design, construct, operate, and maintain a run-off management system to collect and control at least the water volume resulting from a 24-hour, 25-year storm.

E. Collection and holding facilities (e.g., tanks or basins) associated with run-on and run-off control systems must be emptied or otherwise managed expeditiously after storms to maintain the design capacity of the system. Collected material must be disposed of properly.

F. If the treatment zone contains particulate matter which may be subject to wind dispersal, the owner or operator must manage the unit to control wind dispersal.

G. The owner or operator must inspect the unit weekly and after storms to detect evidence of:

1. deterioration, malfunctions, or improper operation of run-on and run-off control systems; and

2. improper functioning of wind dispersal control measures.

H. The administrative authority will specify in the facility permit how the owner or operator will design, construct, operate and maintain the land treatment unit in compliance with this Section.

I. Landfarms shall be isolated from contact with public, private, irrigation, or livestock water supplies, both surface and underground. A permit application shall address the technical requirements of LAC 33:V.Chapters 15, 27, 33, 35, and 37.

J. Requirements

1. Soils shall be fine-grained with high clay or organic content (e.g., CL, OL, MH, CH, and OH under the Unified Soil Classification System).

2. Soils shall maintain a high cation exchange capacity to absorb metallic elements in the waste by natural (pH range of the soil) or artificial means (additives).

3. Landfarms shall be located in a hydrologic section where the historic high water table is at a safe depth below the zone of incorporation, or the water table at the site shall be controlled to a safe depth below this zone (see LAC 33:V.2705.C.2).

4. Topography shall provide for drainage to prevent ponding.

5. Land slope shall be controlled to prevent erosion.

6. Run-off shall be collected and contained and disposed of by irrigation through reapplication to the treatment zone during drought periods, evaporation, or treatment. Any discharge into the off-site environment shall be governed by a NPDES permit.

7. Groundwater monitoring systems shall be installed that meet with the approval of the administrative authority.
