Terms and Conditions for Solid Waste Permit Exemption
 
Waste Materials
Specific Requirements for Activity or Operation
(1)
Drop boxes used solely for collecting recyclable materials
(a) Meet the performance standards of WAC 173-350-040; and
 
(b) Allow department and jurisdictional health department representatives to inspect the drop box at reasonable times for the purpose of determining compliance with this chapter.
(3) Transfer stations and drop box facilities – Permit requirements - Location. There are no specific location standards for transfer stations or drop box facilities subject to this chapter; however, facilities must meet the performance standards of WAC 173-350-040.
(4) Transfer stations and drop box facilities – Permit requirements - Design. Transfer stations and drop box facilities must be designed so that the facilities can be operated to meet the performance standards of WAC 173-350-040, and the following design standards:
(a) Transfer stations must:
(i) Control public access, and prevent unauthorized vehicular traffic and illegal dumping of waste;
(ii) Be sturdy and constructed of easily cleanable materials;
(iii) Provide effective means to control rodents, insects, birds and other vectors;
(iv) Provide effective means to control litter including, but not limited to, orientation of the tipping floor in a manner that prevents prevailing winds from moving waste outside the collection area when other structures are not in place to prevent this;
(v) Provide a tip floor made of impervious material such as concrete or asphalt to prevent soil and groundwater contamination. The surface must be durable enough to withstand damage from operating equipment. The jurisdictional health department may approve other types of surfaces if the applicant can demonstrate that it will prevent soil and groundwater contamination;
(vi) Cover the tipping floor to protect it from precipitation;
(vii) Convey leachate from the tipping floor and any ancillary areas likely to collect leachate, such as wash down areas, to a surface impoundment, tank, or sanitary sewer, or use other methods approved by the jurisdictional health department to prevent uncontrolled discharges;
(viii) Provide for stormwater runoff collection and discharge from a twenty-five year storm;
(ix) Provide pollution control measures to protect air quality; and
(x) Provide all-weather surfaces for vehicular traffic.
(b) Drop box facilities must:
(i) Control public access, and prevent unauthorized vehicular traffic and illegal dumping of waste;
(ii) Provide detachable containers constructed of durable, watertight materials with a lid or screen on top that prevents litter, the loss of materials during transport, and access by rodents and other vectors. When reliably watertight detachable containers cannot be assured, the containers may alternatively be placed on an impervious surface with run-on and runoff controls;
(iii) Be designed so that customers may easily place waste directly into drop boxes; and
(iv) Provide all-weather surfaces for vehicular traffic.
(5) Transfer station and drop box facilities – Permit requirements – Documentation.
(a) The owner or operator must submit facility drawings and construction documents for, at a minimum, any proposed addition or modification of elements described in subsection (4) of this section to the jurisdictional health department for review and approval. The facility drawings and construction documents for proposed construction of engineered features must be prepared by a professional engineer registered in the state of Washington, and must include:
(i) An engineering report that presents the design basis and calculations for the engineered features. The engineering report must demonstrate that the proposed design will meet the performance standards of WAC 173-350-040;
(ii) Scale drawings of the facility including the location and size of waste handling areas, fixed equipment, buildings, stormwater management features where applicable, access roads, traffic patterns, and other constructed areas and buildings integral to facility operation;
(iii) Design specifications for the engineered features of the facility as applicable; and
(iv) For new construction, a construction quality assurance plan that describes monitoring, testing, and documentation procedures that will be performed during construction of the facility, to ensure the facility is constructed in accordance with the approved design.
(b) The owner or operator must provide copies of the construction record drawings for engineered features at the facility and a report documenting facility construction, including the results of observations and any testing carried out as part of the construction quality assurance plan, to the jurisdictional health department and the department. The owner or operator must not commence operation in a newly constructed portion of the facility until the jurisdictional health department has determined that the construction was completed in accordance with the approved engineering report/plans and specifications and has approved the construction documentation in writing.
