§ 94-596. Self-monitoring:  


Latest version.
  • (a)

    Except as noted in subsection (b) below, all industries issued industrial waste permits shall be required to perform self-monitoring and reporting of their permitted discharges to the city-parish consolidated government's POTW.

    (1)

    All handling, preservation, and collection of samples, and laboratory methods and pollutant analyses of samples, (including sampling techniques), are to be submitted as part of a discharge permit application or report, and shall be performed in accordance with approved methods unless otherwise specified in an applicable categorical pretreatment standard and/or wastewater discharge permit. The laboratory used for all analytical work will be on the Louisiana Department of Environmental Quality's approved list for wastewater analysis and will be certified to run the analytical test method that is reported.

    (2)

    Any industry that discharges industrial wastes to the sanitary sewer system of the city-parish consolidated government shall, upon request of the Lafayette Utilities System, install sampling devices, take periodic samples, analyze the samples for the presence and/or quantity of pollutants listed in this article or listed in the permit issued by the department of utilities, and report the results to the wastewater operations manager.

    a.

    Sample collection:

    1.

    Except as indicated in subsection 2. below, the user must collect wastewater samples using flow proportional composite collection techniques. In the event flow proportional sampling is infeasible, the wastewater operations manager may authorize the use of time proportional sampling or a minimum of four grab samples where the user demonstrates that this will provide a representative sample of the effluent being discharged. In addition, grab samples may be required to show compliance with instantaneous discharge limits.

    2.

    Samples for oil and grease, temperature, pH, cyanide, phenols, sulfides, and volatile organic compounds must be obtained using grab collection techniques. Oil and grease samples should be collected as surface grabs.

    (3)

    The frequency of self-monitoring and reporting for any permitted industrial user whether or not subject to national pretreatment requirements shall in no case be less than semiannually, with one sampling and reporting period being the first six months of the calendar year (January through June) and the second sampling and reporting period being the last six months of the year (July through December).

    (4)

    Specific self-monitoring and reporting frequencies (which may be more frequent than twice per year at the discretion of the wastewater operations manager) shall be defined in the industrial user's industrial waste permit issued by the city-parish consolidated government.

    (5)

    If the permitted industrial user performs, at his own discretion or at the specific request of the city-parish consolidated government, more frequent sampling and analysis than called for in the industrial waste permit issued by the city-parish consolidated government, the results of all such additional sampling and analysis shall also be reported to the city-parish consolidated government and shall be included by the city-parish consolidated government when determining compliance with the industrial waste permit and this article and/or for determining surcharge levels for surcharge parameters. Methods of sampling and analysis shall be congruent with approved methods. Self-monitoring shall not replace the regular sampling and testing routine of the city-parish consolidated government.

    (6)

    If the results of the permitted industrial user's wastewater analysis indicate that an effluent violation of the permit has occurred, the industrial user must:

    a.

    Inform the city-parish consolidated government by telephone of the violation within 24 hours of becoming aware of said violation;

    b.

    Within five days of becoming aware of said violation, submit to the city-parish consolidated government a detailed written report specifying:

    1.

    Description and cause of the violation and the impact on the industrial user's compliance status. The description should also include location of discharge, type, concentration and volume of waste, and time, date and city-parish consolidated government personnel notified as required in subsection a. above.

    2.

    Duration of noncompliance, including exact dates and times of noncompliance and, if the noncompliance is continuing, the time by which compliance is reasonably expected to occur.

    3.

    All steps taken or to be taken to reduce, eliminate, and/or prevent recurrence of such a violation.

    c.

    Repeat the sampling and pollutant analysis and submit, in writing, the results of all analyses within 30 days of becoming aware of said violation.

    d.

    If the above repeat sampling shows a continued violation of effluent limitations, the industrial user is referred back to subsections a. through c. of this section.

    (b)

    The city-parish consolidated government, at its own discretion, may perform any or all the sampling and analyses for any permitted industrial user.

    (1)

    In such cases, the industrial waste permit issued to these industrial users shall specifically state that the city-parish consolidated government shall perform all sampling and analyses required under the permit. The minimum frequency for monitoring performed by the city-parish consolidated government shall be as described for industrial user self-monitoring in subsection (a)(3) above (i.e., semiannual). The minimum sampling frequency to be used by the city-parish consolidated government shall be described in the industrial waste permit of those industrial users for which the city-parish consolidated government will perform all sampling and analysis.

    (2)

    The city-parish consolidated government, at its own discretion, may increase the sampling frequency of all such industrial users over-and-above the frequency called for in the industrial waste permit issued to the industrial user or may, at its own discretion, analyze the industrial user's discharge for pollutant parameters not specifically listed in the industrial waste permit issued to the industrial user.

    (3)

    The results of all sampling performed by the city-parish consolidated government shall be used to determine compliance with the industrial user's industrial waste permit and this article and/or for determining surcharge levels for surcharge parameters. The city-parish consolidated government shall invoice and shall be paid by the industrial user for the cost of all labor, sampling and analysis as herein described.

    (4)

    Should the industrial user, at his own discretion or at the specific request of the city-parish consolidated government, perform any sampling and analysis of his permitted discharge, said industrial user shall report the results of said sampling and analysis to the city-parish consolidated government and the results shall be used by the city-parish consolidated government to determine compliance with its industrial waste permit and this article. Methods of sampling and analysis, whether performed by the city-parish consolidated government or the industrial user, shall be congruent with approved methods.

    (c)

    The wastewater operations manager may require owners or occupants who use pretreatment facilities prior to discharging into a sanitary sewer to install such monitoring and recording devices as may be necessary to monitor parameters such as, but not limited to, the following: (1) pH (2) Dissolved oxygen (DO) (3) Total carbon (TC) (4) Temperature (5) Conductivity (6) Specific ions (7) Flow.
