A. 
All users holding industrial discharge permits shall, at a frequency determined by the Director, submit a report as specified on their permit. This report shall include the results of the analysis of wastewater samples indicating the nature and concentration of pollutants in their wastewater that are limited by this Ordinance, and the measured or estimated average and maximum daily flows for the reporting period. All periodic compliance reports must be signed and certified in accordance with this Ordinance.
B. 
All wastewater samples must be representative of the user's typical discharge. Wastewater monitoring and flow measurement facilities shall be at all times, properly operated, kept clean and orderly, and maintained in good working order. The failure of a user to maintain its monitoring facility in satisfactory working condition shall not be grounds for the user to claim that sample results are unrepresentative of its discharge.
C. 
If a user subject to the reporting requirement in this Ordinance monitors any pollutant more frequently than required by the Director, using the procedures prescribed in Sections 6.8 and 6.9 of this Ordinance, the results of the monitoring shall be included in the report.
A. 
All industrial discharge permit holders must notify the Director of any planned significant changes to the user's operations or system that might alter the nature, quality, or volume of its wastewater at least ninety (90) days before the change.
B. 
The Director may require the user to submit such information as is deemed necessary to evaluate the changed condition, including the submittal of a permit application under Section 4.7 of this Ordinance.
C. 
Upon approval of the request by the Town, a Discharge Permit Request may be submitted by the Town to NHDES based on information submitted by the user. All applicable NHDES review fees shall be provided by the user.
D. 
Upon approval of the Discharge Permit Request by NHDES, the Director may issue a permit under Section 5.3 of this Ordinance or modify an existing permit under Section 5.5 of this Ordinance in response to changed conditions or anticipated changed conditions.
E. 
For purposes of this requirement, significant changes include, but are not limited to, flow increases of twenty percent (20%) or greater, and the discharge of any previously unreported pollutants.
A. 
In the case of any discharge, including, but not limited to, accidental discharges, discharges of a non-routine, episodic nature, a non-customary batch discharge, or a slug, that may adversely impact the POTW, the user shall immediately telephone and notify the Director of the incident. This notification shall include the location of the discharge, type of waste, concentration and volume, if known, and corrective actions conducted by the user.
B. 
Within five (5) days following such discharge, the user shall, unless waived by the Director, submit a detailed written report describing the incident, the pollutants involved, the cause(s) of the discharge and the measures to be initiated by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage, or other liability that may be incurred as a result of damage to the POTW, natural resources, or any damage to person or property, nor shall such notification relieve the user of any fines, penalties, or other liability that may be imposed pursuant to this Ordinance. The report must be signed and certified in accordance with Section 4.8 of this Ordinance.
C. 
A notice shall be permanently posted on the user's bulletin board or other prominent location advising employees whom to call in the event of a discharge described in paragraph (A) of this section. Employers shall ensure that all employees who could cause such a discharge to occur are advised of the emergency notification procedure.
D. 
The user shall notify the Director immediately of any changes at its facility that may affect the potential for a slug discharge. The Director may require the user to develop or modify a slug control plan or take other actions to prevent and/or control slug discharges.
Additional reporting requirements may be established by the Director for users that are not required to obtain an industrial discharge permit. Reports may be subject to the reporting requirements of Section 6.3.
If the results of sampling performed by any user indicate an exceedance of the established limit, permit limit, or screening level for a pollutant, or the presence of a previously unreported pollutant, the user must notify the Director within twenty-four (24) hours of becoming aware of the violation. The user shall also repeat the sampling and analysis and submit the results of the repeat analysis to the Director as soon as possible, but no later than thirty (30) days after becoming aware of the violation.
Any discharge into the POTW of a substance that, if otherwise disposed would be a hazardous waste under 40 CFR Part 261 or are hazardous wastes as defined in the NHDES Hazardous Waste Rules, is prohibited.
A. 
All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in these regulations shall be determined in accordance with the techniques prescribed in the Code of Federal Regulations Title 40, Part 136, or as may be revised. Where 40 CFR Part 136 does not contain sampling or analytical techniques for the pollutant in question, sampling and analysis shall be performed by used validated procedures, including those suggested by the Town or other parties.
B. 
A laboratory that is currently certified by the State of New Hampshire to perform the requested tests shall perform all analyses. Original laboratory reports, including all relevant quality control data, shall be submitted as part of each permit application or report. If, for whatever reason, any part of a laboratory report is deleted, augmented, or otherwise changed following its original issuance by the laboratory, then any permit application or report making use of that laboratory data shall clearly and completely identify the original report content and the nature of the change that was made.
A. 
Except as indicated in paragraph (B), below, the user shall collect wastewater samples using 24-hour flow-proportional composite collection techniques. In the event flow-proportional sampling is not feasible, the Director may authorize the use of time-proportional sampling, or a minimum of four (4) 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 demonstrate compliance with instantaneous maximum allowable discharge limitations (e.g., screening levels established to protect worker health and safety). A single grab sample may also be used in place of a composite sample with approval of the Director when:
1. 
The effluent is not discharged on a continuous basis (i.e., batch discharges of short duration), and only when the batch exhibits homogeneous characteristics (i.e., completely mixed) and the pollutant can be safely assumed to be uniformly dispersed;
2. 
Sampling is at a facility where the Director determines that a statistical relationship can be established between previous grab samples and composite data; and
3. 
The waste conditions are relatively constant (i.e., are completely mixed and homogeneous) over the period of the discharge.
B. 
Samples for temperature, pH, phenols, sulfides, oils & grease, and volatile organic compounds shall be obtained using proper grab collection techniques in accordance with 40 CFR 403 Appendix E, where possible.
C. 
Samples shall only be collected by individuals who are properly qualified, through verifiable training and experience, to perform the type of sampling required. The integrity of all samples shall be ensured by following established chain-of-custody practices for evidentiary samples. Sampling and chain-of-custody records shall be maintained in accordance with the permit. Original sampling and chain-of-custody records shall be submitted as part of each permit application or report.
Written reports will be deemed to have been submitted on the date postmarked. For reports that are not mailed, postage prepaid, into a mail facility serviced by the United States Postal Service, the date of receipt of the report shall govern. For electronically submitted reports, the date received shall be determined by the date sent.
Users subject to the reporting requirements of this Ordinance shall create, retain, and make available for inspection and copying, records of all information obtained pursuant to any monitoring activities required by this Ordinance and any additional records of information obtained pursuant to monitoring activities undertaken by the user independent of such requirements. Records shall include the date, exact location, method, and time of sampling, and the name of the person(s) obtaining the samples, the dates analysis was performed, who performed the analysis; the analytical techniques or methods used, and the results of such analysis. These records shall remain available for a period of at least five (5) years. This period shall be automatically extended for the duration of any litigation concerning the user or the Town, or where the user has been specifically notified of a longer retention period by the Director. Records shall be provided upon request to authorized local, state and federal authorities.
