Common use of Periodic Testing Clause in Contracts

Periodic Testing. Producer will conduct periodic testing of the Constituents specified in Table 1 in accordance with the timelines set forth in this Section 4.6 (“Periodic Testing”). For each Periodic Testing event, Producer will collect the Biomethane samples and send them to an independent certified third-party laboratory. Producer will provide at least two (2) business days’ advance notice to NW Natural of Biomethane sampling and NW Natural will have the option to have a representative present to observe the samples being taken. Producer will share the results with NW Natural within five (5) business days of receipt unless immediate action is required as specified in Section 4.11. If the laboratory results from any testing event identify the need for shut-off based on any of the circumstances enumerated in Section 4.11, Producer will immediately notify NW Natural of the results by calling the NW Natural Gas Control phone number set forth in Section 8.1(a), as may be updated from time to time by NW Natural. a) Pipeline Integrity Constituents will be tested once every 3-month period in which injection occurs (samples may not be taken less than sixty (60) days and not more than ninety (90) days from the last testing sample) or until such time they are tested eight (8) times without reaching a Trigger Level identified in Table 1 in Exhibit C for any Pipeline Integrity Constituent, at which point the Pipeline Integrity Constituents will be tested once every 12-month period (samples may not be taken less than nine [9] months and not more than fifteen [15] months from the last testing sample). b) Group 1 Health Constituents i. Group 1 Health Constituents will be tested once every 3-month period in which injection occurs (samples may not be taken less than sixty (60) days and not more than ninety (90) days from the last testing sample). ii. Any Group 1 Health Constituent with a concentration below the Trigger Level identified in Table 1 for eight (8) consecutive tests will be tested once every 12-month period in which injection occurs (samples may not be taken less than nine (9) months and not more than fifteen (15) months from the last testing sample). iii. A Group 1 Health Constituent will become a Group 2 Health Constituent if any testing result indicates a concentration at or above the Trigger Level identified in Table 1 in Exhibit C. c) Group 2 Health Constituents i. Group 2 Health Constituents will be tested once every 3-month period in which injection occurs (samples may not be taken less than sixty (60) days and not more than ninety (90) days from the last testing sample). ii. A Group 2 Health Constituent will become a Group 1 Health Constituent if testing indicates a concentration below the Trigger Level identified in Table 1 in Exhibit C during four (4) consecutive tests. d) For each Periodic Testing event, the Biomethane’s collective potential cancer and non-cancer risk totals will be calculated for the Group 2 Health Constituents. The collective totals are subject to the actions described in Section 4.11. e) NW Natural may, at its discretion, accelerate or modify the Periodic Testing schedule as necessary to ensure the constituent levels are not injurious to pipeline facilities, or present a health and/or safety hazard to employees and/or the general public. NW Natural will provide written notification of modifications of the testing schedule a minimum of thirty (30) days prior to the effective date. f) Producer will be responsible for costs associated with Periodic Testing requirements.
