(a) Industrial sludge

(1) Bulk industrial sludge or industrial sludge sold or given away in a bag or other container shall not be applied to the land if the concentration of any pollutant in the industrial sludge exceeds the ceiling concentration for the pollutant in Table 1 of section504.13. However, the Department may allow, on a case-by-case basis, the application of bulk industrial sludge to the land when the concentration of any pollutant in the industrial sludge exceeds the ceiling concentration for the pollutant in Table 1 of section504.13 provided the application rate is at or below the agronomic rates as defined by section504.11(b)(b). It must be clearly demonstrated to the Department's satisfaction that no adverse impact to public health or the environment will occur in these situations. Additional requirements in permits on management, operational standards, site restrictions, frequency of monitoring, recordkeeping, and reporting may be imposed in the these situations.

(2) If bulk industrial sludge is applied to agricultural land, forest, a public contact site, or a reclamation site, either:
(i) the cumulative loading rate for each pollutant shall not exceed the cumulative pollutant loading rate for the pollutant in Table 2 of section504.13; or

(ii) the concentration of each pollutant in the industrial sludge shall not exceed the concentration for the pollutant in Table 3 of section504.13.

(3) If bulk industrial sludge is applied to a lawn or a home garden, the concentration of each pollutant in the industrial sludge shall not exceed the concentration for the pollutant in Table 3 of section504.13.

(4) If industrial sludge is sold or given away in a bag or other container for application to the land, either:
(i) the concentration of each pollutant in the industrial sludge shall not exceed the concentration for the pollutant in Table 3 of section504.13, or

(ii) the product of the concentration of each pollutant in the industrial sludge and the annual whole sludge application rate for the industrial sludge shall not cause the annual pollutant loading rate for the pollutant in Table 4 of section504.13 to be exceeded. The procedure used to determine the annual whole sludge application rate is presented in appendix A of this part.

(5) The Department may determine on a case-by-case basis that an industrial sludge due to its pollutant content or pollutant concentration may not be land applied or sold or given away.

(b) Pollutant concentrations and loading rates -industrial sludge.

(d) Additional parameters may be required, from the application information or subsequent monitoring, in a permit thereafter, but such needs will be assessed on an individual project basis. Any pollutant required for monitoring under effluent guidelines ( 40 CFR 136; Subchapter N ( 40 CFR Part 400 through 402 and 404 through 471)) may be required to be monitored (in permits) for in the industrial sludge.
