Why We’re Here: • The Legislature charged MDE with the

development of regs for food composting. • Composting is a great way to reduce waste

in landfills, and produce very desirable soil additives.

• However, there are legal and environmental considerations.

• We have been working with a group of composters, academics, County reps, and others to develop sensible regs to make composting easier and yet protect the environment.

• We are here to tell you what we’re doing!

Yard Waste & Composting Laws: From the Environment Article: • §9–1701. … (b) “Compost” means the product of composting in

accordance with the standards established by the Secretary of Agriculture under § 6–221 of the Agriculture Article.

(c) “Composting” means the controlled biological decomposition of organic waste material in accordance with the standards established by the Secretary under this title.

… (s) (1) “Yard waste” means organic plant waste

derived from gardening, landscaping, and tree trimming activities.

(2) “Yard waste” includes leaves, garden waste, lawn cuttings, weeds, and prunings.

Page 5: Department of the Environment Composting Regulations ...mde.state.md.us/programs/Water/Water.../Documents/... · •The Legislature charged MDE with the development of regs for food

Other Pertinent Statutes: • Permits for composting and

distribution of any compost containing sewage sludge are required under Environment Article Sections 9-204 and 233;

• Permits for composting Natural Wood Waste are required under EA Section 9-1708.

Page 6: Department of the Environment Composting Regulations ...mde.state.md.us/programs/Water/Water.../Documents/... · •The Legislature charged MDE with the development of regs for food

Composting Regs: From Md. Dept of Agriculture’s

Definition in COMAR 18.04.01.01A: • (5) "Compost" means a stabilized organic product produced by

the controlled aerobic decomposition process in such a manner that the product may be handled, stored, and applied to the land or used as a soil conditioner in an environmentally acceptable manner without adversely affecting plant growth.

• (6) "Compostable" means any biological material capable of being aerobically decomposed into compost.

• (7) "Composting" is the aerobic degradation of organic matter to make compost.

• (8) "Composting facility" means a facility where solid waste or organic material is processed using composting technology, including:

• (a) Physical turning; • (b) Windrowing; and • (c) Aeration or other mechanical handling of organic matter.

Page 7: Department of the Environment Composting Regulations ...mde.state.md.us/programs/Water/Water.../Documents/... · •The Legislature charged MDE with the development of regs for food

Which Composters Need A Permit NOW? • Sewage Sludge Composting requires a sewage sludge

utilization permit: COMAR 26.04.06, Sewage Sludge Management.

• Natural wood waste composting (NWW) = stumps, brush, limbs, logs, etc. ground into wood chips and composted into mulch – requires a natural wood waste recycling permit: COMAR 26.04.09, Natural Wood Waste.

• Commercial or domestic refuse generally does require a refuse disposal permit under COMAR 26.04.07 - Solid Waste Management.

• All generally need a general or site-specific discharge permit – Mike will explain.

Page 8: Department of the Environment Composting Regulations ...mde.state.md.us/programs/Water/Water.../Documents/... · •The Legislature charged MDE with the development of regs for food

Which DON’T need A Solid Waste Permit? • Yard waste composting = leaves, twigs, grass

clippings and garden waste generally does not need a refuse disposal permit as long as no large wood is included (that needs a NWW Permit), and you have a market for it.

• Food waste and manure MAY not need a refuse disposal permit, depends on what else is in it (packaging, pallets, etc.) and whether you have a market for it.

• Purely governmental Natural Wood Waste operations are exempt from the permit requirements, but should follow the requirements of the regs.

Composting Techniques

• Turned Pile

• Static Pile

• Blanketed Pile

• In-vessel

• All can involve windrows or piles; use of bulking agents to improve aeration, forced air injection or extraction, and liquid addition.

Page 10: Department of the Environment Composting Regulations ...mde.state.md.us/programs/Water/Water.../Documents/... · •The Legislature charged MDE with the development of regs for food

What It ISN’T:

Composting ISN’T:

• Anaerobic

• Piles of Rotting Stuff

• Anaerobic Digestion

Page 11: Department of the Environment Composting Regulations ...mde.state.md.us/programs/Water/Water.../Documents/... · •The Legislature charged MDE with the development of regs for food

So why regulate composters? • Although compost is a valuable product, the process

can be problematic, with risks varying with the feedstocks used.

• Leaves and grass have little impact, but food waste, manure, and other nutrient-rich feedstocks can cause real problems.

• Adverse environmental effects can include surface and groundwater pollution, severe odors and gas production, and the propagation of disease vectors such as rats and flies.

• These are worse if the composting isn’t done properly, e.g., the pile is allowed to become anaerobic. Good practices help!

Page 12: Department of the Environment Composting Regulations ...mde.state.md.us/programs/Water/Water.../Documents/... · •The Legislature charged MDE with the development of regs for food

Examples: New Earth food and industrial residual composter (e.g.,

crab chum, DAF sludge from chicken processors, mushroom house soil, etc.) had to be closed by MDE due to severe environmental problems.

- Runoff from piles generated thick algal mats where it pooled, indicating high nutrient availability

- Groundwater had ammonia and TKN of 490, COD of 2500, BOD 310, P 35 (all PPM).

- On one visit an inspector (me) commented “All the flies in the world are here.”

- Offsite odors from the site were so intense the County ordered them off the property.

- Other sites had major fires and runoff issues.

MDE Composting Workgroup • House Bill 817/Chapter 363, Acts of 2011

required MDE, in consultation with MES and MDA, to: – Study composting in MD, including laws and

regulations – Develop recommendations on how to promote

composting, including programmatic, legislative, or regulatory changes

– Report findings and recommendations to the General Assembly by January 1, 2013

Page 16: Department of the Environment Composting Regulations ...mde.state.md.us/programs/Water/Water.../Documents/... · •The Legislature charged MDE with the development of regs for food

MDE Composting Workgroup • Members included composting industry, legislators, academia,

county recycling coordinators, environmental groups.

• Meetings were held monthly.

• Heard from other states; studied the USCC model rules.

• Technical Subgroup worked on foundation for composting regulations and recommendations and Education and Outreach Subgroup developed recommendations.

• Recommendations included need for legislative authority for composting regulations, extensive outreach and education to various stakeholders, funding for grants/loans to enhance composting, promotion of a variety of compost uses, exemption of backyard composting and some farm composting, etc.

Page 17: Department of the Environment Composting Regulations ...mde.state.md.us/programs/Water/Water.../Documents/... · •The Legislature charged MDE with the development of regs for food

Composting Regulations • House Bill 1440/Chapter 686, Acts of 2013 fulfills a major

recommendation of the Workgroup by providing authority for MDE to adopt regulations on composting. The law also: – removes organic material capable of being composted and

that is actually composted from the definition of solid waste;

– exempts consumers and farmers who compost organic materials generated on a farm or residential site controlled by the consumer or farmer from getting a permit; and

– Establishes enforcement provisions.

Page 18: Department of the Environment Composting Regulations ...mde.state.md.us/programs/Water/Water.../Documents/... · •The Legislature charged MDE with the development of regs for food

Composting Regulations • The Former Technical Subgroup has been meeting since

March 2013 to develop the regulations. Major provisions in the regulations include: – General Permits, Individual Permits, Registrations; – 5 year permit term; – 3 Types of Feedstocks

• Type 1 – yard waste; other materials determined by MDE to have low risk from hazardous substances, human pathogens, and physical contaminants

• Type 2 – source separated organics; approved manure and bedding; approved industrially produced food processing materials; manufactured organics; other materials…

• Type 3 – sewage sludge; biosolids; septage; used diapers; mixed MSW; other materials…
