Alabama Administrative Code › Title 335 - ALABAMA DEPARTMENT OF ENVIRONMENTAL MANAGEMENT › WATER DIVISION - WATER QUALITY PROGRAM › Chapter 335-6-12 - NATIONAL POLLUTANT DISCHARGE ELIMINATION SYSTEM (NPDES) CONSTRUCTION, NONCOAL/NONMETALLIC MINING AND DRY PROCESSING LESS THAN FIVE ACRES, OTHER LAND DISTURBANCE ACTIVITIES, AND AREAS ASSOCIATED WITH THESE ACTIVITIES › Section 335-6-12-.02 - Definitions

Current through Register Vol. 42, No. 9, June 28, 2024
The following words and terms, when used for the purposes of
				  this Chapter, shall have the following meanings unless the context clearly
				  indicates otherwise or unless a different meaning is stated in a definition
				  applicable to only a portion of this Chapter. Unless inconsistent with this
				  Chapter as determined by the Director, other words and phrases used in this
				  Chapter shall have the same meaning as used in Chapters 335-6-3, 335-6-6,
				  335-6-7, 335-6-9, 335-6-10, 335-6-11, and the Alabama Water Pollution Control
				  Act (AWPCA), as amended.
(a) "Alabama
				Handbook" means the Introduction through Appendix A7, inclusive, of the
Alabama Handbook For Erosion Control, Sediment Control, And
				Stormwater Management On Constructions Sites And Urban Areas
,
				Alabama Soil and Water Conservation Committee (ASWCC) (2002).
(b) "Associated Areas" means other onsite or
				adjacent support activities, including but not limited, to construction site
				temporary office space, parking areas, employee work areas, material
				stockpiles, waste or material storage, disposal, equipment storage,
				chemical/fuel storage and staging areas.
(c) "Best Management Practices" (BMPs)
1. BMPs mean planning, project phasing,
				schedules of activities, implementation, operating, and maintenance procedures,
				management strategies, effective treatment practices, and to the extent
				necessary, post-construction follow-up continuing maintenance, that meet or
				exceed recognized effective industry standard practices, that meet or exceed
				the technical standards and guidelines of the Alabama Handbook, and that meet
				or exceed the requirements of this Chapter, that are implemented to
				prevent/minimize pollutant discharges to the maximum extent practicable. BMPs
				also include effective practices to control pollutant discharges from land
				disturbance activities associated with pre-construction testing, site
				assessment, surveying, and other pre-construction development support
				activities. BMPs also include effective practices to control pollutant
				discharges from spillage or leakage, stormwater transport, storage, treatment,
				or disposal.
2. BMPs also mean full
				implementation and continued maintenance of effective structural and
				non-structural practices and planning/management strategies to ensure effective
				erosion and sediment control, and prevent/minimize the introduction of
				pollutants to stormwater and to treat stormwater to remove pollutants to the
				maximum extent practicable prior to discharge. BMPs also mean the treatment of
				construction associated
de minimus
non-stormwater or
				process wastewater discharges authorized pursuant to the requirements of this
				Chapter, including but not limited to, pit dewatering, drilling fluids
				(augering), and the proper handling and disposal of construction wastes, and
				prevention of the discharge of petroleum products, solvents, and other
				chemicals. BMPs also mean implementation of effective construction site
				nutrient management practices, temporary, annual, or perennial vegetation
				management, minimally disturbed natural riparian buffer area, fully vegetated
				filter strips, and streambank management practices. A BMP can be a single
				practice or more than one practice that combined will provide continuing
				effective treatment.
3. Any
				management practice, structure, or procedure, that is not recognized by the
				Department as a BMP based on performance, not installed/implemented correctly,
				not maintained, not adequately or properly located/sited, not suitable for the
				specific site conditions, not designed or configured to control potential or
				existing site conditions where the BMP is located, including but not limited
				to, steep slopes or grades, soils, potential precipitation and size of drainage
				area, which is not consistent with effective erosion and sediment control, that
				does not meet or exceed recognized effective industry standard practices, or
				not in accordance with the Alabama Handbook or other ADEM recognized BMP
				documents, is not considered or recognized as a BMP under this
				Chapter.
