The Scattergood Generation Station (SGS) NPDES Permit No. CA0000370 requires the Western Stormwater Drainage (INT-001E), to be sampled for pH, Total Suspended Solids (TSS) and Oil and Grease on a monthly basis. The sampling point (INT-001E) was not accessible for sampling due to obstructed access. |
To prevent future reoccurrence, the LADWP Wastewater Quality and Compliance Group will coordinate with facility staff to ensure that the facility¿s laboratory personnel have access to all the required sampling points. |

Temperature Daily Maximum limit is 100 Degrees F and reported value was 120 Degrees F at EFF-001. |
To prevent future reoccurrences, to the best of the facility operators¿ ability, they will lower the load when temperatures approach the limit. However, in order for the operator to lower the load, a request must be made and approved by LADWP's Energy Control Center (ECC). As was done this past event, a request to the load dispatchers will be made to lower the load when the temperature begins to approach the 100°F limit. Additionally, divers were deployed to inspect the valves for accuracy and functionality. |
