Agricultural Water Quality Regulations

Any agricultural operation that meets the threshold of a farm is required to follow the Required Agricultural Practices (RAPs). Depending on the size of the operation, there may be additional requirements, see the table below.

Beginning January 15, 2023, any Vermont farm which withdrew 10,000 gallons or more of surface water within a 24-hour period in the preceding calendar year, or 150,000 gallons or more of surface water over any 30-day period in the preceding year, shall file a report with the Vermont Agency of Agriculture, Food & Markets (VAAFM). More information on surface water withdrawal reporting.

Beginning July 1, 2020, AAFM was directed to regulate the generators or haulers of non-sewage waste who are transporting or arranging for the transport of non-sewage waste to a farm for deposit into a manure pit or for use as an input in a methane digester. Common examples of non-sewage waste include dairy and other food processing waste, brewery or winery waste, wash waters, and food residuals. Generators of non-sewage waste who plan to transfer to a farm for deposit in a manure pit or methane digester, must apply to the Non-sewage Waste Transfer Program and receive approval from AAFM before the waste is transferred. More information on non-sewage waste transfer.
