Section 139.101 - General requirementsThis section applies to monitoring systems as defined in the manual referenced in § 139.102(3) (relating to references), installations required or approved under Chapters 122, 124, 127 and 129 or in an order issued under section 4 of the act (35 P.S. § 4004).
(1) The submittal procedures specified in the publication entitled "Continuous Source Monitoring Manual," available from the Department shall be utilized to obtain Department approval. This publication includes:(i) Installation requirements.(ii) Performance specifications.(iv) Reporting requirements.(v) Quality assurance requirements.(vi) Administrative procedures for obtaining Department approval.(2) The monitoring system installation, certification and operation shall be conducted under the direct supervision of persons qualified by training and experience.(3) The monitoring systems may be designed to monitor source emissions or stack emissions if the representativeness of emissions can be verified. The method of conversion of monitoring results to source or stack emissions shall be approved by the Department.(4) The location of monitoring devices shall be approved by the Department prior to installation. The selection of the monitoring location shall utilize applicable criteria in the manual referenced in § 139.102(3). The Department has the authority to determine which of the criteria are applicable. The representativeness of the measurements at the chosen monitoring location shall be verified.(5) The owner of a monitored source shall maintain records containing monitoring information and report data to the Department as specified in the manual referenced in § 139.102(3). The records shall be maintained for 5 years and be available for inspection by Department personnel.(6) The owner of a monitored source shall provide permanent sampling facilities as specified in § 139.1 (relating to sampling facilities) to permit verification testing by the Department. For extractive monitors, calibration gas inlets shall be available as near as possible to the monitor probe inlet to permit the Department to verify calibration of the monitoring system. Facilities shall be approved by the Department prior to construction.(7) Verification testing for monitoring systems shall be in accordance with Subchapter B (relating to monitoring duties of certain sources), and of the manual referenced in § 139.102(3).(8) A quality assurance program shall be established and maintained by the owner of the monitored source. This program shall be in accordance with the criteria in the sources listed in § 139.102.(9) The Department's approval will be based on the criteria specified in the manual referenced in § 139.102(3). Failure to utilize the specified procedures or to conduct the quality assurance program could result in denying or rescinding the Department's approval.(10) The owner of a monitored source shall notify the Department when the monitoring system is inoperative for more than 1 hour during an air pollution episode as specified in Chapter 137 (relating to air pollution episodes). The notice shall be given within 2 hours of the malfunction.(11) Manual sampling conducted under Subchapter B may be required if the Department determines that the monitoring system data is not accurate or that the owner of the monitored source does not conduct the quality assurance program specified in the manual referenced in § 139.102(3).(12) Required monitoring shall meet at least one of the following minimum data availability requirements unless other data availability requirements are stipulated elsewhere in this title, in a plan approval or permit condition under Chapter 127 (relating to construction, modification, reactivation and operation of sources), or in an order issued under section 4 of the act. For purposes of calculating data availability, "process down" time, as specified in the manual referenced in § 139.102(3), shall be considered valid time. (i) In each calendar month, at least 90% of the time periods for which an emission standard or an operational parameter applies shall be valid as set forth in the quality assurance section of the manual referenced in § 139.102(3).(ii) In each calendar quarter, at least 95% of the hours shall be valid as set forth in the quality assurance section of the manual referenced in § 139.102(3).(13) The monitor results shall be expressed in terms of the applicable standard or criteria required. The method used to convert monitor data shall be approved by the Department.(14) Monitoring systems shall comply with the applicable performance specifications section of the manual referenced in § 139.102(3). The Department has the authority to determine which of the performance specifications are applicable.(15) Verification of calibration standards shall be conducted in accordance with the applicable sampling methods in the Department's "Source Testing Manual" or as otherwise approved by the Department. The "Source Testing Manual" may be obtained from the Department. (16) The requirements of this section apply to monitoring to demonstrate compliance with emissions standards and process operational parameter criteria.The provisions of this §139.101 adopted April 27, 1979, effective 8/1/1979, 9 Pa.B. 1447; corrected May 11, 1979, effective 8/1/1979, 9 Pa.B. 1534; amended June 19, 1981, effective 6/20/1981, 11 Pa.B. 2132; amended August 12, 1983, effective 8/13/1983, 13 Pa.B. 2478; amended October 26, 1990, effective 10/27/1990, 20 Pa.B. 5416; amended November 25, 1994, effective 11/26/1994, 24 Pa.B. 5899; corrected January 28, 2000, effective 3/7/1998, 30 Pa.B. 533.
