25 Pa. Code § 250.301 - Scope
(a) This subchapter
sets forth generic Statewide health standards as one of three remediation
standards that a person may select. The Statewide health standards are
concentrations of regulated substances associated with a specific environmental
medium, and are designated as the MSCs. The values used to determine the MSCs
are contained in Appendix A, Tables 1-4 and 6 and are the concentrations of
regulated substances that shall be met to demonstrate attainment of a Statewide
health standard. Appendix A, Table 5 presents the toxicological and physical
parameters used to calculate the MSCs in Appendix A, Tables 1-4.
(b) This subchapter sets forth generic
Statewide health standards for regulated substances determined by the EPA to be
mutagens. Appendix A, Tables 1-4 contain Statewide health standards based upon
the methodology for mutagens in §§
250.306 and
250.307 (relating to ingestion
numeric values; and inhalation numeric values) for the following substances
classified as mutagens:
Regulated Substance | CAS Number |
Acrylamide | 79-06-1 |
Benzo[a]anthracene | 56-55-3 |
Benzidine | 92-87-5 |
Benzo[a]pyrene | 50-32-8 |
Benzo[b]fluoranthene | 205-99-2 |
Benzo[k]fluoranthene | 207-08-9 |
Chromium (VI) | 18540-29-9 |
Chrysene | 218-01-9 |
Dibenzo[a,h]anthracene | 53-70-3 |
Dibromo-3-chloropropane, 1,2- | 96-12-8 |
Dichloromethane | 75-09-2 |
Indeno[1,2,3-cd]pyrene | 193-39-5 |
Methylene bis(2-chloroaniline), 4,4'- | 101-14-4 |
Nitrosodiethylamine, N- | 55-18-5 |
Nitrosodimethylamine, N- | 62-75-9 |
Nitroso-N-ethylurea, N- | 759-73-9 |
Trichloroethylene (TCE) | 79-01-6 |
Trichloropropane, 1,2,3- | 96-18-4 |
Vinyl chloride | 75-01-4 |
(c) This subchapter sets forth minimum
threshold MSCs for soil and groundwater that shall be met to demonstrate
attainment of the Statewide health standards for regulated substances in
Appendix A, Table 6. Minimum threshold MSCs are standards developed for
regulated substances for which no chemical-specific toxicological data
exist.
(d) For regulated substances
which do not have an MSC for the relevant medium on Appendix A, Tables 1-4 or
6, the background standard or site-specific standard shall be met to qualify
for a release of liability under the act.
