Current through Register Vol. 49, No. 13, September 23, 2024
Subpart 1.
Baseline monitoring
reports.
Baseline monitoring reports must include the information in
this part. New sources must include in the report information describing the
method of pretreatment the source intends to use to meet applicable categorical
pretreatment standards. New sources shall give estimates of the information
requested in subparts
5 and
6.
Subp. 2.
Identifying
information.
The industrial user shall submit the name and address of the
facility including the name of the operator and owners.
Subp. 3.
Permits.
The industrial user shall submit a list of any environmental
control permits held by or for the facility.
Subp. 4.
Description of
operations.
The industrial user shall submit a brief description of the
nature, average rate of production, and standard industrial classification of
the operations carried out by the industrial user. The description shall
include a schematic process diagram that indicates points of discharge to the
POTW from the regulated processes.
Subp.
5.
Flow measurement.
The industrial user shall submit information showing the
measured average daily and maximum daily flow, in gallons per day, to the POTW
from regulated process waste streams and other streams as necessary to allow
use of the combined waste stream formula provided in part
7049.0350. The control authority
may allow for verifiable estimates of these flows when justified by cost or
feasibility considerations.
Subp.
6.
Measurement of pollutants.
The industrial user shall:
A. identify the categorical pretreatment
standards applicable to each regulated process; and
B. submit the results of sampling and
analysis identifying the nature and concentration, or mass, when required by
the categorical standard or by the control authority, of regulated pollutants
in the discharge from each regulated process. Both daily maximum and average
concentration, or mass, when required, shall be reported. The sample shall be
representative of daily operations. In cases where the categorical pretreatment
standard requires compliance with a best management plan or pollution
prevention alternative, the industrial user shall submit documentation as
required by the control authority or the applicable categorical pretreatment
standards to determine compliance with the standard.
Subp. 7.
Certification.
A. The industrial user shall submit a
certification consisting of a statement, reviewed by an authorized
representative of the industrial user, as provided in part
7049.0220, and certified by a
qualified professional, indicating whether categorical pretreatment standards
are being met on a consistent basis and, if not, whether additional operation
and maintenance or additional pretreatment is required for the industrial user
to meet the categorical pretreatment standards and requirements. If the
industrial user's categorical pretreatment standard has been modified by a
removal credit as provided in parts
7049.0360 to
7049.0470; the combined waste
stream formula as provided in part
7049.0350; or a fundamentally
different factors variance as provided in part
7049.0480, subpart
2, at the time the industrial
user submits the baseline monitoring reports, the certification and the
compliance schedule in part
7049.0550 pertain to the modified
limits.
B. If an alternate
concentration or mass limit has been calculated according to part
7049.0300, subpart
3, the adjusted limit and
supporting data shall be included.
C. When the POTW performs the required
sampling and analysis in lieu of the categorical industrial user, the
categorical industrial user is not required to submit the compliance
certification under this subpart.
