§ 20695. CIWMB - Cover Performance Standards. [T14:s17683]
The EA may require the following cover performance standards if necessary to control vectors, fires, odors, and blowing litter and to evaluate the suitability of alternative daily or intermediate cover:
(1) Threshold Values-The following shall constitute threshold values for vector populations:
(A) Flies-A fly grill survey value of six (6) or more domestic flies, or observations of domestic flies in the “crawler” stage (newly emerged adults prior to wings becoming functional) at a density of three (3) or more per square yard of surface area at any location on the disposal area. Domestic flies are considered to be those species in the Families: Muscidae (including Anthomyiidae), Calliphoridae, Sarcophagidae, and Drosophilidae.
(B) Domestic Rats-The trapping of one or more domestic rats anywhere on the disposal site. Domestic rats are considered to be any species in the genus Rattus.
(C) Field Rodents-Observation of five (5) or more field rodents feeding on the active face of the disposal site. Field rodents are considered to be any species in the Family Sciuridae.
(D) Mosquitoes-The observation of any immature mosquito stages from water holding waste materials on the disposal site.
(E) Wasps, cockroaches, etc.-The observation of excessive populations utilizing accepted norms.
(2) Inspection Practices
(A) Schedule-Fly grill surveys shall be conducted on each disposal site a minimum of once per week. Sampling to determine the species composition of the fly population shall be conducted a minimum of once per month. Rat trapping surveys shall be conducted at least once each month. Observations for mosquitoes, wasps, cockroaches, “crawler” flies or other types of vectors shall be made during each inspection of the disposal site. The EA may approve alternative inspection schedules or cease inspections if previous inspections or other observations indicate no further threat to public health and safety.
(B) Procedure-Ten (10) fly grill counts shall be made over appropriate attractants on the active face of the disposal site during each inspection utilizing accepted practices to count and record the flies. The five (5) highest counts shall be averaged to obtain the value for that inspection. In sampling to provide qualitative data for the fly species composition on a disposal site, any of the following or other acceptable method for sampling adult flies shall be observed:
-bait traps, exposed for at least a continuous 24-hour period at separate locations, or
-sticky tapes, exposed for a continuous 24-hour period at separate locations, or
-utilization of a standard insect net on the active working face, or
-other approved method to provide a representative sample.
For uniformity of information, one of the approved methods shall be selected for use on a continuing basis at each disposal site.
A minimum of two (2) domestic rat trap lines each containing twenty (20) traps shall be operated for one night on each disposal site at the prescribed frequency. Traps appropriately baited, shall be set at 20-foot intervals in each trap line. One trap line shall be located on or as close to the active face as practical. The other trap line shall be located on the periphery of the site in suitable rodent habitat. On very large sites additional trap lines will be required to provide an adequate sample. Visual observations of field rodents or their signs shall be made and recorded during each inspection.
(C) Equipment-All fly surveys conducted on the active face of the disposal site shall be made with a Scudder fly grill. This device is a square grill consisting of 24 slats, each 3 ' * 3/4 ” * 1/4 ” placed 3/4 ” apart on a z.-shaped framework. Species composition of fly populations at the site shall be made with the use of fly traps, sticky tapes, an insect net, or other approved method to provide a representative sample. Snap traps or live traps, or a combination thereof, of suitable size and design shall be used to capture mature domestic rats.
(D) Records-The following information shall be recorded at a minimum during each inspection: Name of site; location; date of inspection; name of person(s) making the inspection; the time the inspection began; the time the inspection ended; temperature; wind conditions; moisture conditions; sky conditions; shade; attractants, when applicable; results of the 10 Scudder grill counts; number and species of all flies captured; number of domestic rats trapped since the previous inspection; number of field rodents observed (or signs of their presence), and the presence of any mosquitoes, wasps, cockroaches, or other types of vectors.
These records shall be kept up to date and shall be submitted to the EA upon request.
Burning material, or any solid waste at a temperature likely to cause fire, shall not be deposited in the fill. Said material shall initially be deposited in a separate location a sufficient distance from the fill area to prevent fires from spreading to the normal fill area. It shall then be spread in a single layer not exceeding one (1) foot in thickness and immediately covered with a sufficient amount of earth or sprayed with sufficient fire retardant to extinguish all combustion. Final disposition of the material shall not take place until the operator is certain that no further combustion will take place under any conditions.
Fires which originate within the fill shall be handled by removing all the burning material from the fill and extinguishing it as described above, or by in-situ practices approved by the EA, in consultation with the local fire authority. Excavation of burning materials shall be undertaken in a planned and controlled manner; with sufficient fire fighting equipment present to control any “flare-ups” which may occur as outside air reaches the burning materials. The EA shall be immediately notified of any fire.
Accumulation or offsite migration of litter in quantities that create a nuisance, injury to the public and personnel, or cause other problems, shall be prevented.
(d) Alternative Methods
Alternative cover performance standards in lieu of ¶(a) through (c) of this section may be applied by the EA with concurrence by the CIWMB.
