Maine’s LD 1911, signed April 20, 2022, made Maine the first U.S. state to ban sewage sludge land application — with $60 million set aside for farmers already living with what stayed behind.
Maine became the first U.S. state to ban land application of sewage sludge when Governor Janet Mills signed LD 1911 on April 20, 2022. The law arrived after years of legal biosolid spreading had quietly moved PFAS compounds — chemicals that do not break down in soil or water — into farmland and drinking wells across the state. That combination of legal practice and invisible accumulation is what makes the Maine case worth understanding.
PFAS don’t announce themselves. They carry no color, no odor, no warning. They sink through soil layers into groundwater and stay there, moving through the food chain the same way they move through the water table — without announcement.
Quick facts:
– LD 1911 was enacted as Public Law 2021, Chapter 641, and passed both chambers April 15, 2022.
– Maine was the first U.S. state to ban sewage sludge land application as fertilizer.
– The ban covers municipal, commercial, and industrial wastewater sludge, plus compost made from that sludge.
– $60 million in state aid was set aside for farmers whose land was already contaminated.
– The law also prohibits new septage land-application permits where groundwater PFAS exceeds drinking-water standards.
What Maine’s LD 1911 Actually Prohibits
The law’s full title is “An Act To Prevent the Further Contamination of the Soils and Waters of the State with So-called Forever Chemicals.” It bans land application of sludge from municipal, commercial, and industrial wastewater treatment. It also bans compost made with that sludge or septage, and bars sale or distribution of sludge-derived fertilizer products in Maine.
The ban on new septage application permits extends to any site where groundwater already tests above established drinking-water PFAS standards. Exemptions exist for landfill disposal and a specific list of agricultural materials — food waste, crops, brewing residues, seafood byproducts, and lime mud among them — that were not part of the contamination concern driving the bill.
How Maine Is Tracking PFAS After the Ban
Stopping future applications doesn’t address what’s already in the ground. The law authorizes Maine DEP to require wastewater dischargers to sample their effluent for PFAS and report results. DEP’s LD 1911 monitoring program maps those PFAS signatures across wastewater sources statewide.
The fiscal note recorded revenue losses of $1.8 million in FY 2021–22 and $3.6 million in FY 2022–23 from the $10-per-ton sludge handling fee the ban eliminated. Ongoing monitoring and mapping of PFAS effluent sources gives the state the infrastructure to understand the scale of what decades of spreading left behind — even if it cannot undo it.
Closing
Maine farmers who followed every legal guideline handed to them ended up with contaminated soil and compromised wells. The $60 million in state aid, and a ban that passed 85–50 in the House, represent the state’s formal acknowledgment that the guidelines were wrong.
The soil still holds what was spread into it. The ban stopped the next round of damage. That distinction matters.
Frequently Asked Questions
When did Maine’s sewage sludge ban take effect?
LD 1911 was signed April 20, 2022. Specific provisions have phased effective dates ranging from January 1, 2023 through January 1, 2040.
Is Maine really the first state to ban sewage sludge application?
Yes. Multiple sources confirm Maine was the first U.S. state to enact a statewide ban on land application of sewage sludge as fertilizer.
What does the $60 million in Maine aid cover?
State aid of $60 million was set aside for farmers whose land was already contaminated by historic sludge application before the ban.
Are all sludge-derived materials banned under LD 1911?
No. The law exempts food waste, crops, vegetative material, brewing and fermentation residues, seafood byproducts, spent grain, and lime mud from its prohibitions.
