Louisiana Administrative Code
Title 33 - ENVIRONMENTAL QUALITY
Part V - Hazardous Wastes and Hazardous Materials
Subpart 1 - Department of Environmental Quality-Hazardous Waste
Chapter 15 - Treatment, Storage, and Disposal Facilities
Section V-1503 - Site Requirements
Universal Citation: LA Admin Code V-1503
Current through Register Vol. 50, No. 9, September 20, 2024
A. Geology
1. Topographic Relief. The site
should not have any abrupt topographic changes or means should be provided to
guard against slides, slumping, or erosion.
2. Soils. The area should be covered with
natural stable soils of low permeability or a means should be provided,
acceptable to administrative authority, which provide a barrier to penetration
of surface spills or accumulations of hazardous wastes into a subsurface strata
which would have a potential effect on a fresh-water aquifer.
3. Seismic Conditions. Portions of new
facilities where treatment, storage, or disposal of hazardous waste will be
conducted must not be located within 61 meters (200 feet) of a fault which has
had displacement in Holocene time.
B. Hydrology
1. General Requirement. Sites utilized shall
be isolated by means of natural or created boundaries from adjoining land and
from subsurface and surface waters.
2. Drainage. The site must have the
capability to control and/or contain run-off from the maximum rainfall in 24
hours from a 25-year storm (when maximum rainfall records are not available,
the design standard shall be 12 inches below 31 degrees North latitude and 9
inches above 31 degrees North latitude) and must have the capability to divert
run-on from adjoining land (outside limits of hazardous waste site or if part
of an industrial complex, outside limits of company property) from such a storm
from the site (surface and subsurface).
3. Floodplains
a. A facility located in a 100-year
floodplain must be designed, constructed, operated, and maintained to prevent
washout of any hazardous waste by a 100-year flood unless the owner or operator
can demonstrate to the administrative authority that:
i. procedures are in effect which will cause
the waste to be removed safely, before flood waters can reach the facility, to
a location where the wastes will not be vulnerable to floodwaters; or
ii. for existing surface impoundments, waste
piles, land treatment units, landfills, and miscellaneous units, no adverse
effects on human health or the environment will result if washout occurs,
considering:
(a). the volume and physical and
chemical characteristics of the waste in the facility;
(b). the concentrations of hazardous
constituents that would potentially affect surface waters as a result of
washout;
(c). the impact of such
concentrations on the current or potential uses of and water quality standards
established for the affected surface waters; and
(d). the impact of hazardous constituents on
the sediments of affected surface waters or the soils of the 100-year
floodplain that could result from washout.
4. Hurricane-Prone Areas. Sites
located in an area which is historically subject to hurricanes shall be
protected from the entry of water by natural or created barriers certified by a
professional engineer.
5.
Conformity with Existing Restrictions and Permits. Sites located in floodways
or wetlands under control of the U.S. Army Corps of Engineers and/or the
Coastal Zone Management Office must apply for applicable permits. However, to
avoid unnecessarily long licensing periods, the department may accept and
process the application with its final approval dependent upon a similar
approval. Final department action on such a state permit will be taken after
final action on wetlands and coastal zone permits.
6. Areas of Critical Environmental Concern.
Sites located in, or adjacent to, swamps, marshes, floodplains, estuaries,
designated wildlife hatchery areas, habitats of endangered species, and similar
critical environmental areas shall be isolated from such areas by effective
barriers which eliminate possible adverse impacts on such areas due to
operation of the facility.
7. Salt
Dome Formations, Salt Bed Formations, Underground Mines, and Caves. The
placement of any noncontainerized or bulk liquid hazardous waste in any salt
dome formation, salt bed formation, underground mine or cave is
prohibited.
C. Facilities
1. Transportation. Access to sites
by surface and water transportation modes shall be by roads and waterways with
the capacity to accept the demands created by the facility and designed to
avoid, to the extent practical, congestion, sharp turns, obstructions, or other
hazards which are conducive to accidents.
2. Services. Sites shall have convenient
access to required services, including: utilities, medical care, police, fire
protection, and similar services, or provide these services internally in a
manner acceptable to the administrative authority.
3. Buffer Zone
a. General Requirement. Sites shall be
shielded from adjoining noncompatible land uses by space, natural separation,
or other means acceptable to the administrative authority.
b. Minimum Requirements. In no event shall
the buffer be less than that stated for the following sites:
i. sites zoned industrially-sufficient space
for security and drainage control facilities; or
ii. all other locations-200 feet between any
facility (treatment pond, incinerator, tank, etc.) and property line unless a
proper buffer is installed which is acceptable to the administrative authority
(see LAC 33:V.2113 for container requirements).
