§ 27-149. Monitoring and reporting.

(a)

Reports. The following types of reports may be required to be submitted depending on the type of industrial user and compliance history:

(1)

Industrial dischargers are required to file sampling results on an industrial user self-monitoring report form supplied by the department. The director shall require each significant discharger to monitor the facility's discharge and report the results of said monitoring at specified intervals, no less than once every six (6) months. If sampling performed by an industrial user indicates a violation, the user shall notify the control authority within twenty-four (24) hours of becoming aware of the violation. The industrial user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the control authority within thirty (30) days after becoming aware of the violation. Where the control authority has performed the sampling and analysis in lieu of the industrial user, the control authority must perform the repeat sampling and analysis unless it notifies the user of the violation and requires the user to perform the repeat analysis. Resampling is not required if;

(i)

The control authority performs the sampling at the industrial user at a frequency of at least once per month; or

(ii)

The control authority performs sampling at the user between the time when the initial sampling was conducted and the time when the user or the control authority receives the results of this sampling.

(2)

Baseline monitoring reports shall include the following: Nature of the process, volume, rates of flow, volume of water irreversibly used in production, hours of operation, concentrations of controlled pollutants, or other information which relates to the generation of wastes. Such reports may also include the chemical constituents and quantity of liquid materials stored on site even though they are not normally discharged;

(3)

Compliance schedule progress reports;

(4)

Compliance with categorical deadline;

(5)

Periodic compliance reports from categorical industrial users:

a.

Any industrial user subject to a categorical pretreatment standards, after the compliance date of such pretreatment standard, or in the case of a new source, after commencement of the discharge into the POTW, shall submit control authority during the months of June and December, unless required more frequently in the pretreatment standard or by the control authority or by the approval authority, a report indicating the nature and concentration of pollutants in the effluent which are limited by such categorical pretreatment standards. In addition, this report shall include a record of measured or estimated average or maximum daily flows for the reporting period for the discharge required by the control authority. In cases where the pretreatment standard requires compliance with a best management practice or pollution prevention alternative, the user shall submit documentation required by the control authority or the pretreatment standard necessary to determine the compliance status of the user. At the discretion of the control authority and in consideration of such factors as local high or low flow rates, holidays, budget cycles, etc., the control authority may agree to alter the months during which the above reports are to be submitted;

b.

Where the control authority has imposed mass limitations on industrial users as provided for by 40 CFR 403.6(d), the report required by paragraph (a)(1) of this section shall indicate the mass of pollutants regulated by pretreatment standards imposed on the industrial user;

c.

For industrial users subject to equivalent mass or concentration limits established by the control authority in accordance with the procedures in 40 CFR 403.6(c) the report required by paragraph (5)(a) shall contain a reasonable measures of the user's long term production rate. For all other industrial users subject to categorical pretreatment standards expressed only in terms of allowable pollutant discharge per unit of production (or other measure of operation), the report required by paragraph (5)(a) shall include the user's actual average production rate for the reporting period;

(6)

Notice of changed discharge: All industrial users shall promptly notify the control authority (and the POTW if the POTW is not the control authority) thirty (30) days in advance, in writing, of any substantial change in the volume or character of pollutants in their discharge, including the listed or characteristic hazardous wastes for which the industrial user has submitted initial notification under 40 CFR 403.12(p) (see LAC 33:IX.6123.P.);

(7)

Notice of hazardous waste to sewer;

(8)

Notice of potential problems including slug loading: All categorical and non-categorical industrial users shall notify the control authority and the POTW immediately of all discharges that could cause problems to the POTW including any slug loadings, as defined by 40 CFR 403.5(b) and LAC 33:IX.6109.B., by the industrial user. In the case of any discharge, including but not limited to, accidental discharges, discharges of a nonroutine, episodic nature, a noncustomary batch discharge, a slug discharge or slug load, that might cause potential problems for the POTW, the user shall immediately telephone and notify the control authority of the incident. This notification shall include the location of the discharge, type of waste, concentration and volume, if known, and corrective actions taken by the user;

(9)

Periodic compliance reports from non-categorical industrial users. Significant non-categorical industrial users shall submit to the control authority at least once every six (6) months (on dates specified by the control authority) a description of the nature, concentration and flow of the pollutants required to be reported by the control authority. In cases where a local limit requires compliance with a best management practice or pollution prevention alternative, the user must submit documentation required by the control authority to determine the compliance status of the user. These reports shall be based on sampling and analysis performed in the period covered by the report, and performed in accordance with the techniques described in 40 CFR 136 (see LAC 33:IX.4901) and amendments thereto. This sampling and analysis may be performed by the control authority in lieu of the significant non-categorical industrial user.

(b)

Records: All persons who discharge or propose to discharge industrial waste may be required to maintain such records as effluent flows and pollutant concentrations as are necessary to demonstrate compliance with the requirements of this division and with any applicable pretreatment standards. Such records shall be made available upon request by the director.

(c)

Monitoring:

(1)

The owner or operator of any premises or facility discharging industrial wastes may be required to install at his own expense suitable monitoring equipment, including but not limited to, control manholes and/or sampling ports with approved meters and appurtenances to facilitate accurate observation, sampling and measurement of wastes. Such equipment shall be maintained in proper working order and kept safe and accessible at all times;

(2)

The monitoring equipment shall be located and maintained on the industrial disposal premises outside the building. When such a location would be impractical or cause undue hardship on the user, the director may allow a facility to be constructed in the public street or sidewalk area, with the approval of the public agency having jurisdiction over such street or sidewalk, and located so that it will not be obstructed by public utilities, landscaping or parked vehicles. All sampling ports shall be constructed above ground and not subject to any ground or rain water infiltration or dilution. All manholes shall be leak-proof and not subject to any ground or rain water infiltration or dilution;

(3)

When the discharge from an individual discharger enters the parish sewerage system at more than one (1) location, the director may require said discharger to provide current discharge rates occurring at each discharge point. Such discharge rates, expressed as a percentage of the total flow, shall be established by measurement or approved estimate;

(4)

When more than one (1) discharger can discharge into a common sewer, the director may require installation of separate monitoring equipment for each. When there is a significant difference in wastewater characteristics produced by different operations of a single discharger, the director may require that separate monitoring facilities be installed for each separate operation.

(5)

Whether constructed on public or private property, the monitoring facilities shall be constructed in accordance with the director's requirements and all applicable construction standards and specifications.

(d)

Frequency of monitoring. The director shall require each significant discharger to monitor his discharge and report the results of such monitoring at specified intervals. For industrial dischargers not categorized as significant, the director may establish a self-monitoring and reporting schedule, as deemed appropriate for that industry and the characteristics of its discharge.

(e)

Pollutants to be monitored. The director shall provide to each discharger who is determined to require self-monitoring a complete list of wastewater constituents for which the discharger must provide monitoring. The director shall provide to the discharger information regarding discharge prohibitions and limitations for pollutants to be self-monitored.

(f)

Inspection, sampling and analysis.

(1)

Compliance determination. Compliance determinations with respect to section 27-146 prohibitions and limitations may be made on the basis of either instantaneous grab samples or composite samples of wastewater. Composite samples may be taken over a twenty-four-hour period, or over a longer or shorter time span, as determined necessary by the director to meet the needs of specific circumstances. All sampling shall be conducted in accordance with the methods described in 40 CFR 136;

(2)

Analysis of industrial wastewaters. Laboratory analyses of industrial wastewater samples shall be performed in accordance with the procedures described in 40 CFR 136. All pollutant analyses, including sampling techniques, to be submitted as part of a wastewater discharge permit application or report shall be performed in accordance with the techniques prescribed in 40 CFR Part 136 and amendments thereto, unless otherwise specified in an applicable categorical pretreatment standard. If 40 CFR Part 136 does not contain sampling or analytical techniques for the pollutant in question, or where the EPA determines that the 40 CFR Part 136 sampling and analytical techniques are inappropriate for the pollutant in question, sampling and analyses shall be performed using validated analytical procedures, including procedures suggested by the control authority or other parties approved by the EPA. If an industrial user subject to the reporting requirement in 27-149(a) of this section monitors any regulated pollutant at the appropriate sampling location more frequently than required by the control authority, using the procedures prescribed in this section, the results of this monitoring shall be included in the report.

(3)

(g)

Reporting of accidental discharges. If, for any reason, a discharger does not comply with any prohibition or limitations in this division, the discharger shall immediately notify the director so that corrective action may be taken to protect the sanitary sewerage system. In addition, a written report addressed to the director detailing the date, time and cause of the accidental discharge, the quantity and characteristics of the discharge within five (5) days of the occurrence of the noncompliance.

(h)

Record-keeping requirements.

(1)

Any industrial user subject to the reporting requirements established in this section shall maintain records of all information resulting from any monitoring activities required by this section. Such records shall include for all samples:

(i)

The date, exact place, method, and time of sampling and the names of the person or persons taking the samples;

(ii)

The dates analyses were performed;

(iii)

Who performed the analyses;

(iv)

The analytical techniques/methods use; and

(v)

The results of such analyses.

(2)

Any industrial user subject to the reporting requirements established in this section shall be required to retain for a minimum of three (3) years any records of monitoring activities and results (whether or not such monitoring activities are required by this section) and shall make such records available for inspection and copying by the director. This period of retention shall be extended during the course of an unresolved litigation regarding the industrial user or POTW or when requested by the director.
