Lake County commissioners vote to reject proposed countywide septic ordinance after heated public debate

Lake County commissioners voted 4–1 on July 22 to deny a proposed county ordinance that would have required enhanced nutrient‑reducing onsite wastewater systems (or connection to distributed wastewater systems) for many new installations across unincorporated Lake County.

The proposal would have expanded state-mandated requirements tied to Basin Management Action Plans (BMAPs) and House Bill 1379 by applying a 65% nitrogen‑removal performance target to more unincorporated parcels and to some lot sizes not covered by the state requirement. County staff and consultants said the move aimed to reduce nutrient loading to local lakes and springs; opponents called it costly and unclear in enforcement.

Why it mattered: County engineering staff said roughly 47,000 existing septic systems lie inside the county's BMAP areas and estimated that about 9,000 systems would need to be removed or replaced within the next decade to meet nutrient goals. Engineers and DEP officials have warned the county could face state enforcement steps if progress is not demonstrable. Supporters of a stronger local rule said requiring higher‑performance systems on new construction would prevent future increases in nutrient loading; opponents including homeowners and builders said the ordinance would saddle residents with expensive hardware and recurring monitoring costs.

What the board heard: Engineering Director Jeff Earhart outlined the technical approach and offered cost ranges: typical conventional systems at $10,000–$13,000, distributed wastewater systems (DWTS) around $20,000 (the county presently subsidizes some conversions with a grant that covers installed costs), advanced treatment units (ATUs) commonly $25,000–$30,000 plus monitoring fees of roughly $500–$600 per year, and centralized sewer conversions in the roughly $50,000–$75,000 range per connection. Earhart said the county has already installed roughly 90 subsidized DWTS units with state and county funding and is pursuing additional grant funding.

Public commenters and industry voices pressed the board from multiple angles. Septic industry representatives and long‑time homeowners warned about maintenance, pump failures, power outages and the practical costs of ATUs or utility-style maintenance fees. Advocates and water‑quality experts urged action to protect springs and lakes and noted research linking on‑site systems to nutrient loading in some basins.

Board decision and next steps: Commissioners ultimately voted to deny the draft county ordinance and asked staff to return with a revised approach that focuses on the state BMAP areas and aligns with the state permitting transition to the Department of Environmental Protection. Commissioner John Smith framed his opposition as a concern about “government overreach” and cost burdens for homeowners; Commissioner Parks, a longtime proponent of water‑sensitive standards in some growth areas, said he supported using the BMAP geography and working with the state and cities on coordinated measures. The board directed staff to refine the proposal and to increase public outreach and education about existing grant programs for replacements.

The action does not change the state requirements that already apply inside BMAP areas; it removed a proposed, broader local mandate that had aimed to require ATUs or DWTS use for a wider set of new systems. County staff said they will return with revised language and more detailed cost and program options for board consideration.

Ending note: Commissioners stressed the need for clearer public information and for pursuing state and grant funding to help homeowners that choose to transition away from conventional septic systems. If the county advances new local rules later, staff said the board would aim to protect low‑income households with exemptions or subsidies and to coordinate with DEP and municipal partners.
