Common use of Monitoring Reports Clause in Contracts

Monitoring Reports. Written discharge monitoring reports shall be filed by the 31st day of the month following the reporting period (the reporting period is specified in Part B of this program). In addition an annual report shall be filed as indicated in F.3 below. The reports shall comprise the following: a. Letter of Transmittal A letter transmitting the essential points in each report should accompany each report. Such a letter shall include a discussion of any requirement violations found during the last report period, and actions taken or planned for correcting the violations. If the Dischargers have previously submitted a detailed time schedule for correcting requirement violations, a reference to the correspondence transmitting such schedule will be satisfactory. If no violations have occurred in the last report period this shall be stated in the letter of transmittal. Monitoring reports and the letter transmitting the monitoring reports shall be signed by a principal executive officer at the level of vice president or his duly authorized representative, if such representative is responsible for the overall operation of the facility from which the discharge originates. The letter shall contain a statement by the official, under penalty of perjury, that to the best of the signer’s knowledge the report is true, complete, and correct. b. Each monitoring report shall include a compliance evaluation summary. The summary shall contain: 1) Concentration Limits for the Westport Landfill for all constituents of concern except ammonia, are “laboratory non-detect” based upon laboratory non-detect results for background concentrations of the listed COCs. As such, a non-statistical method is appropriate to determine whether a measurably significant release has occurred from the Westport Landfill. Therefore, any reported laboratory detection at a point of compliance monitoring well is considered a potential release. For ammonia, a statistically significant increase shall be evaluated using a statistical method acceptable to the Regional Board staff. Any potential release must be evaluated through additional monitoring and analyses acceptable to the Executive Officer. 2) A graphic description of the direction of groundwater flow under/around the waste management unit, based upon the water level elevations obtained during the monitoring period and pertinent visual observations. 3) The method and time of water level measurement, the type of pump used for purging, pump placement in the well; method of purging, pumping rate, equipment and methods used to monitor field pH, temperature, and conductivity during purging, calibration of the field equipment, results of pH, temperature, and conductivity testing, and the method of disposing of the purge water. 4) Type of pump used, pump placement for sampling, a detailed description of the sampling procedure; number and description of equipment, field and travel blanks; number and description of duplicate samples; type of sample containers and preservatives used, the date and time of sampling, the name and qualifications of the person actually taking the samples, and any other observations. c. A map or aerial photograph shall accompany each report showing observation and monitoring station locations. d. Laboratory statements of results of analyses specified in Part B, Table A must be included in each report. The director of the laboratory whose name appears on the laboratory certification shall supervise all analytical work in his/her laboratory and shall sign all reports of such work submitted to the Board. 1) The methods of analyses and detection limits must be appropriate for the expected concentrations. Specific methods of analyses must be identified. If methods other than EPA approved methods or Standard Methods are used, the exact methodology must be submitted for review and approved by the Executive Officer prior to use. 2) In addition to the results of the analyses, laboratory quality assurance/quality control (QA/QC) information must be included in the monitoring report. The laboratory QA/QC information should include the method, equipment and analytical detection limits; the recovery rates; an explanation for any recovery rate that is less than 80% of the specific laboratory recovery limits; the results of equipment and method blanks; the results of spiked and surrogate samples; the frequency of quality control analysis; and the name and qualifications of the person(s) performing the analyses. e. An evaluation of the effectiveness of the leachate monitoring or control facilities, which includes an evaluation of leachate buildup within the disposal units, a potentiometric surface map, a summary of leachate volumes removed from the units, and a discussion of the leachate disposal methods utilized. f. A summary and certification of completion of all standard observations for the waste management unit, the perimeter of the waste management unit, and the receiving waters.
