California Alternative Manure Management Practices Program (AMMP)

The California Department of Food and Agriculture's Alternative Manure Management Program (AMMP) awards competitive grants to California dairy and livestock operations for the implementation of non-digester manure management practices and technologies that result in long-term methane emission reductions and maximize environmental benefits.

Alternative manure management practices involve handling manure in ways that don't involve using an anaerobic digester. Currently, eligible practices for funding through AMMP include: pasture-based management; alternative manure treatment and storage (such as compost bedded pack barns); and solid separation or conversion from flush to scrape in conjunction with some form of drying or composting of collected manure.

California farmers, ranchers, and California Native American Tribes are eligible to apply. Individuals and business entities receiving grant award funds must be located in California with a physical California business address.

The project site must be located on a commercial California dairy or livestock operation.

• A dairy operation is defined as an entity that operates a dairy herd, which produces milk or cream commercially, and whose bulk milk or bulk cream is received or handled by any distributor, manufacturer, or any nonprofit cooperative association of dairy producers.

• A livestock operation is defined as an entity raising farm animals such as cattle, poultry, goats, sheep, swine and horses.
