(1) Applicability. These standards apply to
facilities that engage in landspreading disposal of solid wastes. These
standards do not apply to:
(a) Facilities
utilizing sludge, woodwaste or other primarily organic sludges according to the
Municipal and Domestic Sludge Utilization Guidelines WDOE
82-11, specified in WAC
173-304-300(4) and
(5);
(b) Agricultural solid wastes resulting from
the operation of a farm including farm animal manure and agricultural residues;
and
(c) Inert wastes and demolition
wastes.
(2) Owners or
operators of landspreading disposal facilities shall meet the minimum
functional standards for performance of WAC
173-304-460(2)
and the general facilities standards of WAC
173-304-405.
(3) Owners or operators of landspreading
disposal facilities shall meet the locational standards of WAC
173-304-130.
(4) Minimum functional standard for design.
Owners or operators of landspreading disposal facilities shall design
landspreading facilities so as to:
(a) Provide
interim waste storage facilities that meet the requirements of WAC
173-304-400 standards (i.e., for
piles, surface impoundments, etc.);
(b) Collect and treat all runoff from a
twenty-four hour, twenty-five year storm, and divert all run-on for the maximum
flow of a maximum twenty-five year storm around the active area;
(c) Avoid standing water anywhere on the
active area;
(d) Avoid slopes and
other features that will lead to soil and waste erosion, unless contour plowing
or other measures are taken to avoid erosion;
(e) Monitor groundwater according to WAC
173-304-490; and
(f) Control access to site by fencing or
other means and erect signs.
(5) Minimum functional standards for
maintenance and operation. Owners or operators of landspreading disposal
facilities shall maintain and operate the facilities so as to:
(a) Avoid any landspreading disposal of
garbage or medical waste;
(b)
Analyze solid wastes according to the requirements spelled out in the
Municipal and Domestic Sludge Utilization Guidelines WDOE
82-11;
(c) Avoid applying wastes at
rates greater than ten times agronomic rates using the proposed cover crop, or
depths greater than would allow for discing the soil by tracked
vehicles;
(d) Provide discing of
soils during the growing season and after each application of waste to maintain
aerobic soil conditions, minimize odors and lessen runoff;
(e) Avoid applying waste to any active area
having standing water;
(f) Conform
to the operating plan and the requirements of WAC
173-304-405;
(g) Avoid food chain crops during the active
life of the facility and until demonstrated to be safe, after closure,
according to the closure and post-closure plans filed with the plan of
operation. Specific approval in writing from the jurisdictional health
department is required for any landspreading disposal facility that is used to
raise food crops after closure. Any new owner or operator of a closed
landspreading disposal facility shall notify the jurisdictional health
department within sixty days of the purchase; and
(h) Provide for a written contract between
landowners, waste generators, waste haulers and waste operators requiring
compliance with rules as a condition of the contract.
(6) Minimum functional standards for closure.
(a) All owners or operators of landspreading
disposal facilities shall close in such a manner as to comply with WAC
173-304-407;
(b) Financial assurance. All owners or
operators of landspreading disposal facilities shall have a written estimate,
in current dollars, of the cost of closing the facility. The closure cost
estimate must equal the cost of closure at the point in the operating life of
the facility when the extent and manner of operation would make closure the
most expensive, as indicated by the closure plan.
In addition, all facilities shall have a written post-closure
estimate, in current dollars, the cost of post-closure monitoring and
maintenance during the post-closure period.
