APPLICABILITY; COMPLIANCE SCHEDULES
Env-Wq 1701.01 Purpose. The purpose of these rules is to establish
water quality standards for the state’s surface water uses as set forth in RSA
485-A:8, I, II, III and V. These standards are intended to protect
public health and welfare, enhance the quality of water and serve the purposes
of the federal Clean Water Act, 33 U.S.C. 1251 et seq., and RSA
485-A. These standards provide for the
protection and propagation of fish, shellfish, and wildlife, and provide for
such uses as recreational activities in and on the surface waters, public water
supplies, agricultural and industrial uses, and navigation in accord with RSA
485-A:8, I and II.

Env-Wq 1703.22 Notes
For Table 1703-1. The following
shall apply to Table 1703-1:
(a)
The letter “a” shall indicate that the freshwater and saltwater aquatic
life criteria for ammonia are shown in Env-Wq 1703.25 through Env-Wq 1703.32.
(b)
The letter “b” shall indicate that the criteria refer to the inorganic
form only.
(c)
The letter “c” shall indicate that these criteria for the protection of
human health are based on carcinogenicity using a risk factor of one in
1,000,000, while the human health criteria without this footnote are based on
systemic toxicity. Other risk factors
shall be allowed only as specified in Env-Wq 1703.20.
(d)
The letter “d” shall indicate that criteria for these metals are
expressed as a function of the water effect ratio (WER) as defined in 40 CFR
131.36(c), and that because the values displayed in Table 1703-1 correspond to
a WER of 1.0, metals criteria for different WERs shall be determined using the
procedures described in the EPA publication “Interim Guidance on Determination
and Use of Water-Effect Ratios for Metals”, EPA-823-B-94-001, dated February
1994, available as noted in Appendix B, provided that for copper, either of the
following references, both available as noted in Appendix B, may be used:
(1) The
“Streamlined Water-Effect Ratio procedure for Discharges of Copper”,
EPA-822-R-01-005, dated March 2001; or
(2) The
Biotic Ligand Model (freshwater only) as described in “Aquatic Life Ambient Freshwater Quality Criteria -
Copper”,
EPA-822-R-07-001, dated February 2007.
(e)
The letter “e” shall indicate that the following classes of compounds
have 2 or more isomers and the appropriate aquatic life criteria apply to the
sum of the concentrations of each isomer:
(1) BHC;
(2) Chlorinated benzenes;
(3) Chlorinated naphthalenes;
(4) Chloroalkyl ethers;
(5) Dichlorobenzenes;
(6) Dichloroethylenes;
(7) Dichloropropanes;
(8) Dichloropropenes;
(9) Dinitrotoluenes;
(10) Haloethers;
(11) Halomethanes;
(12) Nitrophenols;
(13) Nitrosamines;
(14) PCB;
(15) Phthalate esters;
(16) Polynuclear
aromatic hydrocarbons;
(17) Tetrachloroethanes;
and
(18) Trichlorinatedethanes.
(f) The letter “f”
shall indicate that the freshwater aquatic criteria for these metals are
expressed as a function of the total hardness, as mg/l CaCO3 of the
surface water, and that because the values displayed in Table 1703-1 correspond
to a total hardness of 20 mg/l the aquatic life criteria for other hardness
values expressed as calcium carbonate shall be calculated using the equations
and tables in Env-Wq 1703.23 and Env-Wq 1703.24.
(g) The letter “g” shall indicate that if the methylmercury concentration in the edible portion of the
aquatic species of concern exceeds 0.3 mg/kg, a risk assessment shall be
conducted to determine whether a consumption advisory
should be issued for the surface water.
If a consumption advisory is issued by the
department, the surface water shall be considered in non-attainment of the fish
and/or shellfish consumption designated uses and in violation of these surface
water quality regulations.
(h)
The letter “h” shall indicate that the freshwater aquatic life criteria
for pentachlorophenol are expressed as a function of pH. Values displayed in Table 1703-1 correspond to
a pH value of 6.5. For other pH values,
the formulas shown in Env-Wq 1703.32 shall be used.
(i) The letter “i”
shall indicate that the values presented for aquatic life protection are
dissolved metals and for hardness-dependent metals are based on a hardness of
20 mg/L. To convert dissolved to total
recoverable metal, the equations and tables in Env-Wq 1703.23 shall be
used. To calculate dissolved or total
recoverable fresh water criteria for hardness-dependent metals for hardness
values other than 20 mg/l, the equations and tables shown in Env-Wq 1703.23 and
Env-Wq 1703.24 shall be used.
(j)
The letter “j” shall indicate that these human health criteria prevent
taste and odor effects in the surface water and in fish and other aquatic life
as prohibited in Env-Wq 1703.03(c)(1)c. and (3).
(k)
The letter “k” shall indicate that these criteria are based on EPA’s
304(a) criteria in the 1980 documents listed below and were derived to be used
as instantaneous maximum values, or to be applied after division by 2, to
obtain a value comparable to an acute criterion derived using the 1985
Guidelines, when assessment is done using an averaging period:
(1) Aldrin/Dieldrin,
document number
440/5-80-019;
(2) Chlordane, document number 440/5-80-027;
(3) DDT, document number 440/5-80-038;
(4) Endosulfan,
document number
440/5-80-046;
(5) Endrin,
document number 440/5-80-047;
(6) Heptachlor, document number 440/5-80-052;
(7) Hexachlorocyclohexane,
document number 440/5-80-054; or
(8) Silver, document number 440/5-80-071.
(l) The letter “1” shall indicate that there is a more
stringent drinking water maximum contaminant level (MCL) specified in Env-Dw 700, so if the surface water is a source for a
public water system as defined in RSA 485:1-a, XV or is within 20 miles
upstream of any active surface water intake for a public water system, the
department shall use the MCL values shown in table 1703-2A, below, for the
water and fish ingestion human health criteria:
