Louisiana Administrative Code › Title 33 - ENVIRONMENTAL QUALITY › Part V - Hazardous Wastes and Hazardous Materials › Subpart 1 - Department of Environmental Quality-Hazardous Waste › Chapter 5 - Permit Application Contents › Subchapter E - Specific Information Requirements › Section V-532 - Special Part II Information Requirements for Drip Pads

Current through Register Vol. 50, No. 6, June 20, 2024
A. Except as otherwise provided by LAC
					 33:V.Chapter 15, owners and operators of hazardous waste treatment, storage, or
					 disposal facilities that collect, store, or treat hazardous waste on drip pads
					 must provide the following additional information:
1. a list of hazardous wastes placed or to be
					 placed on each drip pad;
2. if an
					 exemption is sought to LAC 33:V.Chapter 33, as provided by LAC 33:V.3301,
					 detailed plans and an engineering report describing how the requirements of LAC
					 33:V.3301 will be met;
3. detailed
					 plans and an engineering report describing how the drip pad is or will be
					 designed, constructed, operated and maintained to meet the requirements of LAC
					 33:V.2805, including the as-built drawings and specifications. This submission
					 must address the following items as specified in LAC 33:V.2803:
a. the design characteristics of the drip
					 pad;
b. the liner system;
c. the leakage detection system, including
					 how the system is designed to detect the failure of the drip pad or the
					 presence of any releases of hazardous waste or accumulated liquid at the
					 earliest practicable time;
d.
					 practices designed to maintain drip pads;
e. the associated collection
					 system;
f. control of run-on to the
					 drip pad;
g. control of run-off
					 from the drip pad;
h. the interval
					 at which drippage and other materials will be removed from the associated
					 collection system and a statement demonstrating that the interval will be
					 sufficient to prevent overflow onto the drip pad;
i. procedures for cleaning the drip pad at
					 least once every seven days to ensure the removal of any accumulated residues
					 of waste or other materials, including but not limited to rinsing, washing with
					 detergents or other appropriate solvents, or steam cleaning and provisions for
					 documenting the date, time, and cleaning procedure used each time the pad is
					 cleaned;
j. operating practices and
					 procedures that will be followed to ensure that tracking of hazardous waste or
					 waste constituents off the drip pad due to activities by personnel or equipment
					 is minimized;
k. procedures for
					 ensuring that, after removal from the treatment vessel, treated wood from
					 pressure and nonpressure processes is held on the drip pad until drippage has
					 ceased; including recordkeeping practices;
l. provisions for ensuring that collection
					 and holding units associated with the run-on and run-off control systems are
					 emptied or otherwise managed as soon as possible after storms to maintain
					 design capacity of the system;
m.
					 if treatment is carried out on the drip pad, details of the process equipment
					 used and the nature and quality of the residuals;
n. a description of how each drip pad,
					 including appurtenances for control of run-on and run-off, will be inspected in
					 order to meet the requirements of LAC 33:V.2805. This information should be
					 included in the inspection plan submitted under LAC 33:V.517.G;
o. a certification signed by an independent,
					 qualified professional engineer stating that the drip pad design meets the
					 requirements of LAC 33:V.2805.A-F;
p. a description of how hazardous waste
					 residues and contaminated materials will be removed from the drip pad at
					 closure, as required under LAC 33:V.2809.A. For any waste not to be removed
					 from the drip pad upon closure, the owner or operator must submit detailed
					 plans and an engineering report describing how LAC 33:V.2521.A and B will be
					 complied with. This information should be included in the closure plan and,
					 where applicable, the post-closure plan submitted under LAC
					 33:V.517.M.
