Current through Register Vol. 35, No. 18, September 24, 2024
A.
Except as provided for in 19.15.30.12 NMAC a responsible person shall, within
60 days of receipt of the director's written notice that the division requires
an abatement plan, submit an abatement plan proposal to the director for
approval. The responsible person may submit stage 1 and stage 2 abatement plan
proposals together. For good cause shown, the director may allow for a total of
120 days to prepare and submit the abatement plan proposal.
B. Voluntary abatement.
(1) A person wishing to abate water pollution
in excess of the standards and requirements set forth in 19.15.30.9 NMAC may
submit a stage 1 abatement plan proposal to the director for approval.
Following the director's approval of a final site investigation report prepared
pursuant to stage 1 of an abatement plan, a person may submit a stage 2
abatement plan proposal to the director for approval.
(2) Following approval of a stage 1 or stage
2 abatement plan proposal under Paragraph (1) of Subsection B of 19.15.30.13
NMAC the person submitting the approved plan shall be a responsible person
under 19.15.30 NMAC for the purpose of performing the approved stage 1 or stage
2 abatement plan. Nothing in 19.15.30 NMAC precludes the director from applying
19.15.29.11 NMAC to a responsible person if applicable.
C. Stage 1 abatement plan. The stage 1 of the
abatement plan's purpose is to design and conduct a site investigation that
adequately defines site conditions, and provide the data necessary to select
and design an effective abatement option. Stage 1 of the abatement plan may
include the following information depending on the media affected, and as
needed to select and implement an expeditious abatement option:
(1) descriptions of the site, including a
site map, and of site history including the nature of the release that caused
the water pollution, and a summary of previous investigations;
(2) site investigation work plan that
defines:
(a) site geology and hydrogeology;
the vertical and horizontal extent and magnitude of vadose-zone and
ground-water contamination; subsurface hydraulic conductivity; transmissivity,
storativity and rate and direction of contaminant migration; inventory of water
wells inside and within one mile from the perimeter of the three-dimensional
body where the standards set forth in Subsection C of 19.15.30.9 NMAC are
exceeded; and location and number of wells the pollution actually or
potentially affects; and
(b)
surface water hydrology, seasonal stream flow characteristics, ground
water/surface water relationships, the vertical and horizontal extent and
magnitude of contamination and impacts to surface water and stream sediments;
the magnitude of contamination and impacts on surface water may be, in part,
defined by conducting a biological assessment of fish, benthic macro
invertebrates and other wildlife populations; seasonal variations should be
accounted for when conducting these assessments;
(3) monitoring program, including sampling
stations and frequencies, for the abatement plan's duration that may be
modified, after the director's approval, as the responsible person creates
additional sampling stations;
(4)
quality assurance plan, consistent with the sampling and analytical techniques
listed in Subsection B of 20.6.2.3107 NMAC and with 20.6.4.14 NMAC of the water
quality standards for interstate and intrastate surface waters in New Mexico,
for all work to be conducted pursuant to the abatement plan;
(5) a schedule for stage 1 abatement plan
activities, including the submission of summary quarterly progress reports, and
the submission, for the director's approval, of a detailed final site
investigation report; and
(6)
additional information that may be required to design and perform an adequate
site investigation.
D.
Stage 2 abatement plan.
(1) A responsible
person shall submit a stage 2 abatement plan proposal to the director for
approval within 60 days, or up to 120 days for good cause shown, after the
director's approval of the final site investigation report prepared pursuant to
stage 1 of the abatement plan. The responsible person may submit a stage 1 and
2 abatement plan proposal together. Stage 2 of the abatement plan's purpose is
to select and design, if necessary, an abatement option that, when implemented,
results in attainment of the abatement standards and requirements set forth in
19.15.30.9 NMAC, including post-closure maintenance activities.
(2) Stage 2 of the abatement plan should
include, at a minimum, the following information:
(a) a brief description of the current
situation at the site;
(b)
development and assessment of abatement options;
(c) a description, justification and design,
if necessary, of the preferred abatement option;
(d) modification, if necessary, of the
monitoring program the director approved pursuant to stage 1 of the abatement
plan, including the designation of pre- and post-abatement-completion sampling
stations and sampling frequencies to be used to demonstrate compliance with the
standards and requirements set forth in 19.15.30.9 NMAC;
(e) site maintenance activities, if needed,
the responsible person proposes to perform after abatement activities
terminate;
(f) a schedule for the
duration of abatement activities, including the submission of summary quarterly
progress reports;
(g) a public
notification proposal designed to satisfy the requirements of Subsections B and
C of 19.15.30.15 NMAC; and
(h)
additional information that may be reasonably required to select, describe,
justify and design an effective abatement option.
