Current through Vol. 41, No. 13, March 15, 2024
(a)
General. The applicant shall submit sampling plans for baseline
monitoring, OPDES permit monitoring, and OPDES permit renewal monitoring for
DEQ approval. Sampling plans shall consider the environmental and spatial
variability of the waterbody, including limnological, hydrologic, seasonal, and
temporal variation. The sampling plans shall also consider both the internal
and external loading and nutrient cycling.
(b)
Baseline characterization.
The provisions of this Subsection shall be used to establish a baseline
characterization of the IPR receiving waterbody before the IPR Source Water
discharge begins.
(1)
Baseline
characterization sampling plan. The permittee shall submit a baseline
characterization sampling plan to DEQ for review and approval. The plan shall
meet the minimum requirements outlined in this Subchapter.
(2)
Duration. The baseline
characterization of the waterbody shall include data collected for a minimum of
one (1) year. Length of monitoring plan may be adjusted by DEQ based on
location and parameter.
(3)
Frequency. Sampling frequency for each parameter is subject to DEQ
approval and shall be identified in the sampling plan. Sampling frequency may
be adjusted by DEQ based on location and parameter. Each sampling event shall
occur at least once per month so that a scientifically defensible data set will
be generated after one (1) year. At least ten (10) data points per monitoring
site are required for a baseline data set to be considered complete.
(4)
Spatial. Sampling locations
for each parameter are subject to DEQ approval.
(5)
Baseline waterbody monitoring
list. The list of parameters monitored to establish a baseline shall be
robust enough to establish a scientifically defensible baseline for all factors
of concern in the receiving waterbody. The required parameters for baseline
characterization are subject to DEQ approval. Additional information can be
found in Subchapter 7 of this Chapter.
(6)
SWS-R Waterbodies. Baseline
sampling of SWS-R waterbodies shall meet the requirements of OAC
252:740-13.
(c)
OPDES waterbody monitoring requirements. The provisions of this
subsection shall be used to establish OPDES permit waterbody monitoring
requirements.
(1)
Monitoring
requirements. The permittee shall submit a waterbody monitoring plan to
DEQ for review and approval. The approved monitoring plan shall be part of the
OPDES permit. The plan shall meet the minimum requirements outlined in this
Subchapter. Monitoring shall be adequate to characterize the accumulation and
concentration of conservative substances.
(2)
Frequency. Sampling
frequency for each parameter is subject to DEQ approval.
(3)
Spatial. Sampling location
for each parameter is subject to DEQ approval.
(4)
OPDES waterbody monitoring
list. The OPDES permit establishes waterbody monitoring requirements.
The parameters subject to the routine OPDES waterbody monitoring may be a
reduced list, utilizing surrogates and parameters likely to be present in
discharge. Monitored parameters are subject to DEQ approval. Additional
information can be found in Subchapter 7 of this Chapter.
(5)
SWS-R Waterbodies. OPDES
sampling of SWS-R waterbodies shall meet the requirements of OAC
252:740-13.
(d)
OPDES permit renewal sampling requirements. The provisions of this
subsection shall be used to establish monitoring requirements for renewal of
the OPDES permit.
(1)
Monitoring
requirements. The permittee shall submit a sampling plan to DEQ for
approval. The sampling plan shall address the sampling requirements for permit
renewal and these requirements shall be included in the permit. Sampling
results shall be included with the OPDES renewal application. The sampling
requirements may be updated during the OPDES permit renewal process with DEQ
approval.
(2)
Frequency. OPDES permit renewal sampling occurs once every five
years during OPDES permit renewal.
(3)
Spatial. Sampling locations
are subject to DEQ approval.
(4)
OPDES permit renewal monitoring list. The waterbody shall be
monitored for a more comprehensive list of parameters during the OPDES permit
renewal cycle, occurring once every five years. The sampled parameters are
subject to DEQ approval. Additional information can be found in Subchapter 7 of
this Chapter.
(e)
Lake and stream monitoring reports. OPDES waterbody monitoring
sampling plan shall include a proposed LMR form for DEQ approval. The LMR form
shall provide all relevant information. LMR forms shall be completed and
submitted in accordance with Subchapter 7 of this Chapter.
