New Mexico Administrative Code › Title 20 - ENVIRONMENTAL PROTECTION › Chapter 6 - WATER QUALITY › Part 4 - STANDARDS FOR INTERSTATE AND INTRASTATE SURFACE WATERS › Section 20.6.4.9 - OUTSTANDING NATIONAL RESOURCE WATERS

Current through Register Vol. 35, No. 13, July 16, 2024
A.
Procedures
				for nominating an ONRW:
Any person may nominate a surface water of the
				state for designation as an ONRW by filing a petition with the commission
				pursuant to 20.1.6 NMAC, Rulemaking Procedures - Water Quality Control
				Commission. A petition to designate a surface water of the state as an ONRW
				shall include:
(1) a map of the surface water
				of the state, including the location and proposed upstream and downstream
				boundaries;
(2) a written statement
				and evidence based on scientific principles in support of the nomination,
				including specific reference to one or more of the applicable ONRW criteria
				listed in Subsection B of this section;
(3) water quality data including chemical,
				physical or biological parameters, if available, to establish a baseline
				condition for the proposed ONRW;
(4) a discussion of activities that might
				contribute to the reduction of water quality in the proposed ONRW;
(5) any additional evidence to substantiate
				such a designation, including a discussion of the economic impact of the
				designation on the local and regional economy within the state of New Mexico
				and the benefit to the state; and
(6) affidavit of publication of notice of the
				petition in a newspaper of general circulation in the affected counties and in
				a newspaper of general statewide circulation.
New Mexico Administrative Code › Title 20 - ENVIRONMENTAL PROTECTION › Chapter 6 - WATER QUALITY › Part 4 - STANDARDS FOR INTERSTATE AND INTRASTATE SURFACE WATERS › Section 20.6.4.10 - REVIEW OF STANDARDS; NEED FOR ADDITIONAL STUDIES

Current through Register Vol. 35, No. 13, July 16, 2024
A. Section 303(c)(1) of the federal Clean
				Water Act requires that the state hold public hearings at least once every
				three years for the purpose of reviewing water quality standards and proposing,
				as appropriate, necessary revisions to water quality standards.
B. In accordance with
				40 CFR
				131.10(i), when an existing
				use, as defined under
				20.6.4.7
				NMAC, is higher quality water than prescribed by the designated use and
				supporting evidence demonstrates the presence of that use, the designated use
				shall be amended accordingly to have criteria no less stringent than the
				existing use.
C. It is recognized
				that, in some cases, numeric criteria for a particular designated use may not
				adequately reflect the local conditions or the aquatic communities adapted to
				those localized conditions. In these cases, a water quality criterion may be
				modified to reflect the natural condition of a specific waterbody. The
				modification of the criterion does not change the designated use; the
				modification only changes the criterion for that specific waterbody. When
				justified by sufficient data and information, a numeric water quality criterion
				may be adopted or modified in accordance with Subsection F of 20.6.4.10 and
				Subsection G of 20.6.4.10 NMAC, to protect the attainable uses of the
				waterbody.
D. The removal or
				amendment of a designated use to a designated use with less stringent criteria
				can only be done through a use attainability analysis in accordance with
				20.6.4.15
				NMAC.
E. It is also recognized that
				contributions of water contaminants by diffuse nonpoint sources of water
				pollution may make attainment of certain criteria difficult. Revision of these
				criteria may be necessary as new information is obtained on nonpoint sources
				and other problems unique to semi-arid regions.
F.
Site-specific criteria.
(1) The commission may adopt site-specific
				numeric criteria applicable to all or part of a surface water of the state
				based on relevant site-specific conditions such as:
(a) actual species at a site are more or less
				sensitive than those used in the national criteria data set;
(b) physical or chemical characteristics at a
				site such as pH or hardness alter the biological availability and/or toxicity
				of the chemical;
(c) physical,
				biological or chemical factors alter the bioaccumulation potential of a
				chemical;
(d) the concentration
				resulting from natural background exceeds numeric criteria for aquatic life,
				wildlife habitat or other uses if consistent with Subsection G of 20.6.4.10
				NMAC; or
(e) other factors or
				combination of factors that upon review of the commission may warrant
				modification of the default criteria, subject to EPA review and
				approval.

B.
Critical low flow:
The
				critical low flow of a stream at a particular site shall be used in developing
				point source discharge permit requirements to meet numeric criteria set in
				20.6.4.97
				through
				20.6.4.900
				NMAC and Subsection F of
				20.6.4.13 NMAC.
(1) For human health-organism only criteria,
				the critical low flow is the harmonic mean flow. For ephemeral waters the
				calculation shall be based upon the nonzero flow intervals and modified by
				including a factor to adjust for the proportion of intervals with zero flow.
				The equations are as follows:
Harmonic Mean =
				  __
n
__
[SIGMA] 1/Q
where
n
= number of flow values
and
Q
= flow value
Modified Harmonic Mean =
where,
Qi
= nonzero flow
Nt
= total number of flow values
and
N0
= number of
				  zero flow values
(2) For all
				other narrative and numeric criteria, the critical low flow is the minimum
				average four consecutive day flow that occurs with a frequency of once in three
				years (4Q3). The critical low flow may be determined on an annual, a seasonal
				or a monthly basis, as appropriate, after due consideration of site-specific
				conditions.

				  plant life or property, or unreasonably interfere with the public welfare or
				  the use of property.
A.
Bottom
				deposits and suspended or settleable solids:
(1) Surface waters of the state shall be free
				of water contaminants including fine sediment particles (less than two
				millimeters in diameter), precipitates or organic or inorganic solids from
				other than natural causes that have settled to form layers on or fill the
				interstices of the natural or dominant substrate in quantities that damage or
				impair the normal growth, function or reproduction of aquatic life or
				significantly alter the physical or chemical properties of the
				bottom.
(2) Suspended or settleable
				solids from other than natural causes shall not be present in surface waters of
				the state in quantities that damage or impair the normal growth, function or
				reproduction of aquatic life or adversely affect other designated

Current through Register Vol. 35, No. 13, July 16, 2024
A.
Regulatory requirements for a use
				attainability analysis.
Whenever a use attainability analysis is
				conducted, it shall be subject to the requirements and limitations set forth in
				40 CFR Part 131 , Water Quality Standards; specifically, Subsections 131.3(g),
				131.10(g), 131.10(h) and 131.10(j) shall be applicable. In accordance with
				40 CFR
				131.10(i), and
				20.6.4.10
				NMAC, the amendment of a designated use, based on an existing use with more
				stringent criteria, does not require a use attainability analysis.
(1) The commission may remove a designated
				use, that is not an existing use, specified in Section 101(a)(2) of the federal
				Clean Water Act or adopt subcategories of a use in Section 101(a)(2) of the
				federal Clean Water Act requiring less stringent criteria only if a use
				attainability analysis demonstrates that attaining the use is not feasible
				because of a factor listed in
				40 CFR
				131.10(g). Uses in Section
				101(a)(2) of the federal Clean Water Act, which refer to the protection and
				propagation of fish, shellfish and wildlife and recreation in and on the water,
				are also specified in Subsection B of
				20.6.4.6
				NMAC.
(2) A designated use cannot
				be removed if it is an existing use unless a use requiring more stringent
				criteria is designated.
