New proposal for Condition E.1(b) fill criteria

Notes

An email chain between Joan Marchioro (Washington Attorney General’s office) and Tom Newlon (Port of Seattle) discussing a revised proposal for Condition E.1(b) regarding fill criteria for imported fill material at an embankment project. The proposal introduces a ‘drainage layer cover’ concept and outlines the use of Synthetic Precipitation Leaching Procedure (SPLP) as an alternative method to demonstrate suitability of fill materials. The draft language requires SPLP test results to be provided to Ecology at least ten business days prior to fill placement.
