Exhibit 2116 AR033733: Email on Sea-Tac Clean Water Act Section 401/402 Split

Notes

Internal email from Tom Luster to Kevin Fitzpatrick dated January 12, 2000, discussing the legal distinction between Clean Water Act Section 401(d) and Section 402(a) as applied to Sea-Tac Airport water quality (WQ) and State Environmental Policy Act (SEA/SEPA) policies. Email quotes statutory language verbatim: 401(d) uses mandatory ‘shall’ language for effluent limitations and monitoring requirements as conditions on Federal licenses or permits, while 402(a) uses discretionary ‘either/or’ language allowing the EPA Administrator to issue NPDES discharge permits meeting either all applicable requirements under sections 1311, 1312, 1316, 1317, 1318, and 1343, or interim conditions. Luster notes a forthcoming discussion memo on applying this distinction to WQ/SEA policies. AR033733, ECY00007257, Exhibit-2116.
