Note to paragraph (b). The following codes of practice may be used to comply with this paragraph (b):
Maximum Leak Detection Rate Per Test Section Volume
Test section volume (gallons) | Semiannual test-leak detection rate not to exceed (gallons per hour) | Annual test-leak detection rate not to exceed (gallons per hour) |
[LESS THAN]50,000 | 1.0 | 0.5 |
[GREATER THAN EQUAL TO]50,000 to [LESS THAN]75,000 | 1.5 | 0.75 |
[GREATER THAN EQUAL TO]75,000 to [LESS THAN]100,000 | 2.0 | 1.0 |
[GREATER THAN EQUAL TO]100,000 | 3.0 | 1.5 |
Phase In For Piping Segments [GREATER THAN EQUAL TO]100,000 Gallons In Volume
First test | Not later than October 13, 2018 (may use up to 6.0 gph leak rate). |
Second test | Between October 13, 2018 and October 13, 2021 (may use up to 6.0 gph leak rate). |
Third test | Between October 13, 2021 and October 13, 2022 (must use 3.0 gph for leak rate). |
Subsequent tests | After October 13, 2022, begin using semiannual or annual line testing according to the Maximum Leak Detection Rate Per Test Section Volume table above. |
