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.

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](https://reader034.vdocument.in/reader034/viewer/2022042101/5e7e4c36ef90fe2ae62251f6/html5/thumbnails/6.jpg)
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](https://reader034.vdocument.in/reader034/viewer/2022042101/5e7e4c36ef90fe2ae62251f6/html5/thumbnails/7.jpg)
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](https://reader034.vdocument.in/reader034/viewer/2022042101/5e7e4c36ef90fe2ae62251f6/html5/thumbnails/8.jpg)
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.
![Page 9: 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](https://reader034.vdocument.in/reader034/viewer/2022042101/5e7e4c36ef90fe2ae62251f6/html5/thumbnails/9.jpg)
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](https://reader034.vdocument.in/reader034/viewer/2022042101/5e7e4c36ef90fe2ae62251f6/html5/thumbnails/10.jpg)
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](https://reader034.vdocument.in/reader034/viewer/2022042101/5e7e4c36ef90fe2ae62251f6/html5/thumbnails/11.jpg)
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](https://reader034.vdocument.in/reader034/viewer/2022042101/5e7e4c36ef90fe2ae62251f6/html5/thumbnails/12.jpg)
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](https://reader034.vdocument.in/reader034/viewer/2022042101/5e7e4c36ef90fe2ae62251f6/html5/thumbnails/16.jpg)
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](https://reader034.vdocument.in/reader034/viewer/2022042101/5e7e4c36ef90fe2ae62251f6/html5/thumbnails/17.jpg)
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](https://reader034.vdocument.in/reader034/viewer/2022042101/5e7e4c36ef90fe2ae62251f6/html5/thumbnails/18.jpg)
