Alternative Manure Management Program (AMMP)

What is the alternative manure management program?
CDFA's Alternative Manure Management Program (AMMP) provides financial assistance for the implementation of non-digester manure management practices in California, which will result in reduced greenhouse gas emissions. CDFA received $99 million from the Greenhouse Gas Reduction Fund in 2017 and plans to allocate between $19-$33 million for AMMP and $61-$75 million for DDRDP in 2018.

What is an alternative manure management practice?
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 based management; solid separation or conversion from flush to scrape in conjunction with some form of drying or composting of collected manure.

How is AMMP Funded?
CDFA receives funding from the Climate Investments program for methane emissions reductions from dairy and livestock operations.

What have been the benefits?
The 58 AMMP projects awarded so far are expected to reduce greenhouse gas emissions by an estimated 716,800 metric tons of CO2e over 5 years.

Are you currently accepting applications?
No. The application period closed on May 22, 2018. 63 applications were received for a total funding request of $34,458,949.
