Section 6-6 - Design and Construction Standards

Universal Citation: WY Code of Rules 6-6

Current through September 21, 2024

(a) Waste management units: The size, type and number and purpose of all solid waste management units and equipment shall be described. This information shall also include a description of the capacity of the solid waste management units and equipment in terms of how much waste can be transferred and treated per hour, day, month or year and the maximum quantity of wastes, both treated and untreated, that can be stored in each solid waste management unit.

(b) Fences and gates: Other than mobile facilities, each facility shall be fenced and equipped with a gate that can be locked. Facilities do not need to be fenced and equipped with a gate that can be locked if the facility is located in a remote or industrial area that already has adequate access control features in place to meet the intent of this standard. Appropriate measures shall be used to restrict access to mobile treatment facilities.

(c) Access signs: Each point of access shall be identified by a sign that shall be easily readable, maintained in good condition, and contain, at a minimum, the following information:

(i) The facility name.

(ii) The name and phone number of the responsible person to contact in the event of emergencies.

(iii) The hours of operation if the facility is open to the public.

(iv) Depending on the particular waste type, additional information describing the particular hazards of the waste may also be required.

(d) Traffic signs: Each facility shall have signs to direct traffic to the proper waste management area, if the facility is open to the public.

(e) Waste management unit signs: Solid waste management units and equipment used to manage treated or untreated waste shall be identified by a sign or label that shall be easily readable, maintained in good condition and identify the name of the solid waste management unit or equipment and the waste type contained in the solid waste management unit.

(f) Access roads: Facility access roads shall be constructed to enable use under inclement weather conditions as applicable.

(g) Fire lanes and buffer zones: For those facilities where any waste management occurs outdoors, the facility shall have a fire lane/buffer zone constructed around all active solid waste management units and equipment or within the site perimeter fence. The width of the fire lane/buffer zone shall be a minimum of twenty (20) feet, but may be wider depending on the specific waste type and the ability of fire fighting equipment to properly operate within the facility.

(h) Surface water structures: For those facilities where any waste management occurs outdoors, the facility shall have surface water structures to control surface water run-on and run-off. Surface water structures shall be designed and constructed to:

(i) At fixed facilities, prevent flow onto the active portion of the facility during the peak discharge from a 25-year storm.

(ii) At fixed facilities, collect and control runoff from the active portion of the facility from at least the water volume from a 24-hour, 25 year storm.

(iii) At mobile facilities, control run-on and runoff from the active portion of the facility.

(iv) At all facilities, sediment control structures shall be designed and constructed in accordance with Chapter 11 of the Water Quality Rules and Regulations.

(i) Waste containment: Units shall be designed and constructed to contain the wastes within the unit and prevent the migration of contaminants. Solid waste management units that manage liquid waste shall also meet the following standards:

(i) Above ground tanks and containers shall be equipped with low-permeability secondary containment systems that provide a secondary means of containment for the entire capacity of the largest single container and sufficient freeboard to contain precipitation.

(ii) Below ground tanks or containers shall be designed and constructed with leak detection systems.

(iii) Ponds shall be designed and constructed in accordance with Chapter 11 of the Water Quality Rules and Regulations.

(iv) Open-topped tanks, containers and ponds that contain wastes that are either petroleum-based or have a pH less than 3 or greater than 10 shall be designed and constructed with netting that is adequate to prevent access by migratory birds.
