Please exercise caution. DO NOT open attachments or click links from unknown senders or unexpected email - STS-Security. *** Good Morning Shannon, One issue noted with the Draft permit is that it does not use the correct Wasteflow Description that was provided in the updated submittal. Specifically, Pump and Haul Site #3 still reflects the TCO Compound, where it should be Building 150 (Marinite/Carpenter Shops). Also, there is no mention of the second discharge location that is located at lat/lon: 35.778265, -83.974374 and flows to Hall Road Meter. Right now the permit states that there is a single dedicated manhole. Could these changes be made in the final permit issued? Please let me know if you have any questions.
