Wyoming Administrative Code › Agency 020 - Environmental Quality, Dept. of › Sub-Agency 0011 - Water Quality › Chapter 15 - USE OF SURFACE DISPOSAL OF BIOSOLIDS, APP. A-C › Part C - SURFACE DISPOSAL › Appendix A - Procedure to Determine The Annual Whole Sludge Application Rate For Biosolids

Current through July 13, 2024
Section 14(a) (iv) (B) requires that the product of the
					 concentration for each pollutant listed in Table 4 of Section 14 in biosolids
					 sold or given away in a bag or other container for application to the land and
					 the annual whole sludge application rate (AWSAR) for the biosolids not cause
					 the annual pollutant loading rate for the pollutant in Table 4 of Section 14 to
					 be exceeded. This appendix contains the procedure used to determine the AWSAR
					 for a biosolids that does not cause the annual pollutant loading rates in Table
					 4 of Section 14 to be exceeded.
The relationship between the annual pollutant loading rate
					 (APLR) for a pollutant and the annual whole sludge application rate (AWSAR) for
					 a biosolids is shown in equation (1).
APLR = C x AWSAR X 0.001 (1)
Where:
APLR = Annual pollutant loading rate in kilograms per
					 hectare per 365 day period.
C = Pollutant concentration in milligrams per kilogram of
					 total solids (dry weight basis).
AWSAR = Annual whole sludge application rate in metric tons
					 per hectare per 365 day period (dry weight basis).
0.001 = A conversion factor.
To determine the AWSAR, equation (1) is rearranged into
					 equation (2):
AWSAR =
APLR
(2)
C x 0.001
The procedure used to determine the AWSAR for a biosolids
					 is presented below. PROCEDURE:
(i) Analyze a sample of the biosolids to determine the
					 concentration for each of the pollutants listed in Table 4 of Section 14 in the
					 biosolids.
(ii) Using the pollutant concentrations from Step 1 and the
					 APLRs from Table 4 of Section 14, calculate an AWSAR for each pollutant using
					 equation (2) above.

				  and
(c)
Monitoring
				  results
: Monitoring results from a release detection method required
				  under Section 14 through 17 that indicate a release may have occurred unless
				  the monitoring device is found to be defective, and is immediately repaired,
				  recalibrated or replaced, and additional monitoring does not confirm the
				  initial result.
(d)
Off-site Impacts.
Owners and/or operators of storage tank
				  systems, and owners of former storage tank sites, shall follow the applicable
				  procedures in Section 20 or 21 to determine if the storage tank system is the
				  source of off-site impacts. These impacts include the discovery of regulated
				  substances (such as the presence of free product or vapors in soils, basements,
				  utility lines, nearby surface water and groundwater) that have been observed by
				  the department or brought to its attention by another party.
