These abbreviations mean: For all surface waters with an actual water supply use, the
less restrictive of the following two options shall apply as numerical standards, as
specified in the Basic Standards and Methodologies at 31.11(6);
(i) existing quality as of January 1, 2000; or
(ii) Iron = 300 pg/I (dissolved)
Manganese = 50 pg/I (dissolved)
S04 = 250 mg/I
For all surface waters with a "water supply" classification that are not in actual use as a
water supply, no water supply standards are applied for iron, manganese or sulfate,
unless the Commission determines as the result of a site-specific rulemaking hearing that
such standards are appropriate.
(c) As used in the "Temporary Modifications and Qualifiers" column of the tables, the term
"type i" refers to a temporary modification adopted pursuant to subsection 31.7(3)(a)(i) of
the Basic Standards and Methodologies for Surface Water (i.e., "where the standard is
not being met because of human-induced conditions deemed correctable within a twenty
(20) year period"). The term "type iii" refers to a temporary modification adopted pursuant
to subsection 31.7(3)(a)(iii) of the Basic Standards and Methodologies for Surface Water
(i.e., "where there is significant uncertainty regarding the appropriate long-term
underlying standard").
(3) Table Value Standards
In certain instances in the attached tables, the designation "TVS" is used to indicate that for a
particular parameter a "table value standard" has been adopted. This designation refers to
numerical criteria set forth in the Basic Standards and Methodologies for Surface Water. The
criteria for which the TVS are applicable are on the following table.
