Document Type
MND - Mitigated Negative Declaration

Mainly agriculturally zoned land

Document Description
The Conditional Waiver would regulate discharge from vineyards in the Napa River and Sonoma Creek watersheds. The Conditional Waiver applies to a group of existing and new vineyards with specific size, slope, and soil type that meet the eligibility and would require: 1) submittal of a Notice of Intent to comply, 2) preparation of a Farm Water Quality Plan that identifies vineyard and road management practices to reduce discharge, 3) implementation of these management practices, and 4) submittal of annual compliance reports. The Conditional Waiver implements the Napa River and Sonoma Creek sediment Total Maximum Daily Loads with the overarching goals of reducing nonpoint source pollutant discharges from vineyard properties and protecting and enhancing beneficial uses, including the protection of anadromous fish habitat.
