Clean Energy Results ProgramCERP – What is it?MassDEP promoting clean energy projects at
sites MassDEP regulatesLandfillsContaminated sites/brownfieldsWastewater treatment and drinking water treatment
facilitiesWater supplies
Coordination with other agencies on clean energy projects (DOER, MassCEC, DAR, EPA)
Clean Energy Results ProgramTypes of clean energy projects MassDEP
involved with:Solar PVWindCombined heat and power (CHP)Energy efficiency projects (pumps, variable speed
motors, etc.)In-conduit hydroAnaerobic digestion (AD)BiomassRenewable thermal
Focus on OrganicsWhat is going on with organics?
Where are organics going now?Where will organics go in the future?
2010 Solid Waste Master Plan GoalsReduce solid waste
disposal by 2 million tons/year by 2020Reduce disposal of
organics (food waste) by 350,000 tons per year
Develop infrastructure to support organics diversionDevelop 250,000–300,000
tpy of processing capacity and supporting collection infrastructure
5
Why focus on food waste/organics?Simply put – there’s a lot of it out there!2010 MSW disposal = 4.7 M tons Food waste & other organics
>20% of the 4.7 M tons, or >1 million tons per year
Running out of disposal capacity as landfills close
We need to reduce reliance on disposal facilities
6
Benefits of ADOpportunity to digest organics and generate
clean energy, and/or compost to produce soil amendments & fertilizers.
Waste management solutions for: dairy manure & wasteswastewater residualsbusinesses & institutions (i.e., food processors, large institutional cafeterias, etc.).
Reduces reliance on disposal capacity.Utilize excess capacity at WWTP digesters
7
2010 Capacity for OrganicsFarm-based and commercial food waste
diversion (~70,000 tons per year)70 composting operations registered with
Dept. of Agricultural ResourcesCommercial compostingFood recovery programsRendering
200 municipal and private leaf and yard waste compost sites
8
2010 Anaerobic Digestion Capacity6 Wastewater Treatment Plants (4 use
energy)4 Food Processors (effluent pre-treatment)2 Dairy Farms (AD under construction)
2013 Waste Characterization Data

Diversion of OrganicsMulti-faceted approach to organics
management:Food recovery first (food pantries, etc.)Waste food and other organics diversion from
disposal to: Animal Feed Composting Anaerobic Digestion with energy recovery
Stakeholders Turning food waste into energy involves
numerous stakeholders:MunicipalitiesOrganics generatorsPrivate sector waste management businessesState agencies
Multiple state agencies have roles to playCoordination is critical:
Leverage or modify pre-existing regulations, policies and programs
Ensure grant and loan programs are targeted to right audience
Location of Food Waste Generators
13From 2010 Master Plan
Encouraging ADWhat Were the Problems?No regulatory “home” for ADNo allowance for Wastewater Treatment
Plants to accept organics in addition to sludge
Were there sufficient incentives? Was there a sufficient supply of organic
materials?If an organics waste ban was issued,
would there be an outcry by those affected?
15
Approach to Encouraging ADMix of Regulatory Changes and Incentives:
Regulations and Policies Solid waste siting regulations Wastewater treatment facility regulations Solid waste waste ban regulations Waste ban guidance and policies
Incentives Grant and loan programs administered by
MassDEP, MassCEC, DOER and DAR
MassDEP Regulations Revisions to SW Siting
Regulations Treat AD more like recycling
or composting than solid waste
Establish appropriate permitting pathway and standards
Two permit levels based on 100 tpd threshold General Permit Recycling, Composting or
Conversion Permit Only source-separated
organic materials Design & operations info Vector/odor control Contingency plans Products/residuals
Siting Co-digestion of Sludge and Food Waste not at WWTP Requires a Solid Waste Site
Assignment
MassDEP RegulationsRevisions to Waste
Water Treatment Facility RegulationsAllow WWTP to
manage food waste in digesters
Requires plan approval by DEP
Organic Waste Ban RegulationEffective Oct. 1, 2014Applies to generators
of > 1 ton/week~1700 entities
affectedMust separate food
waste, vegetative material at the source
Does not apply to wastewater residuals
Does not apply to residences

The Organics BanThe organics ban went into effect on 10/1/14Large percentage of organics already being divertedTremendous amount of outreach by MassDEP
recycling program to prepare for the banVery successful rollout of the banSignificant amount of positive press coverage has
helped get the word outLittle to no opposition to the organics ban
Many generators (groceries, schools, etc.) already diverting
Realizing cost savings on disposal
Production Incentives2002 Renewable Portfolio Standard, RECs
2008 Alternative Energy Portfolio Standard (CHP)
2009 “Virtual” Net Metering for Farm AD
2012 “Virtual” Net Metering for all AD (up to 2 MW)
2014 Raised the Net Metering Caps
Grant and Loan Opportunities2006 Renewable Energy Trust grants2009 MassSave CHP grants(DOER, Electric Distribution Companies)2011 Sustainable Materials Recovery Program municipal grants (MassDEP)2011 Commonwealth Organics-to-Energy grants (MassCEC)

AD/SSO
Where are We Now?Power output from AD = ~1.4 MWOrganics diversion to AD = ~62,000 tpyPotential power output from AD = ~23 MW
by 2020Potential organics diversion to AD =
~500,000 tpy by 2020
Organics Diversion WinsIncrease food donations
for those in needDivert organics from
disposalReduce GHG productionGenerate clean,
renewable power with AD
Reduce cost of disposalProduce useful products
such as fertilizer or compost
Generate jobsFor farms, happy cows!
