Committee clarifies 500‑foot setback for high‑volume fueling stations; forwards ZTA 25‑06 2–1

A Montgomery County Council committee voted to forward Zoning Text Amendment (ZTA) 25‑06 to the full council with a committee recommendation of 2–1 after clarifying how the existing 500‑foot setback for high‑volume filling stations is measured.

ZTA 25‑06 targets filling stations that dispense at least 3,600,000 gallons of fuel per year — a threshold used in prior federal and county guidance that captures large retail or highway fueling operations rather than neighborhood stations. The amendment does not change the 500‑foot distance itself; it clarifies the point from which the distance is measured and adjusts the measurement point for environmentally sensitive features.

Under the committee’s adopted language, the 500‑foot setback will be measured from the fuel dispenser (the hose when it is parked) for schools, parks, playgrounds, day‑care centers and outdoor cultural/recreation uses. In addition, the committee accepted the Planning Board’s recommended modification that requires environmentally sensitive areas — such as wetlands, streams and floodplains — to be measured from the underground storage tank footprint rather than the fuel dispenser. Planning staff said the change is intended to reflect the different physical pathways by which airborne emissions (measured from the dispenser) and subsurface contamination (measured from tanks) can affect surrounding land.

The measure also clarifies that a lawful fueling station that meets the high‑volume threshold would not automatically become a nonconforming use if a protected use (for example, a park or school) locates nearby after the station was built. The committee added language that requires any expansion of a qualifying station to maintain the 500‑foot setback from the appropriate measurement point.

Background and public testimony

The 3,600,000‑gallon threshold dates to federal practice used for school siting and earlier county debates. Planning staff told the committee an average convenience fueling station sells roughly 4,000 gallons per day, so only a small share of retail or highway filling stations meet the ZTA’s high‑volume threshold. The ZTA’s sponsors said the amendment was meant to provide permitting clarity rather than to change the county’s protective distances.

The Planning Board reviewed the ZTA and recommended two technical amendments: (1) measure environmentally sensitive‑area setbacks from underground storage tanks, and (2) preserve the 500‑foot measurement when assessing whether a fueling station remains conforming after a new use appears nearby. The Office of Legislative Oversight (OLO) issued a Racial Equity and Social Justice (RESJ) statement and said it could not reliably anticipate the racial equity impacts, but noted published evidence that the adverse health effects of living near fueling operations are more frequently borne by communities of color and lower‑income residents.

Committee discussion

Committee members discussed community health concerns tied to vehicle queuing at large‑volume stations and the history of a local dispute around a proposed large fueling facility. Some members urged a stricter measurement point; others urged clarity so the county can move forward with an approved, large mixed‑use project in an underserved part of the county.

Ben Robert of Planning explained staff’s reasoning: measuring from pumps captures the point of airborne emissions and queueing, while measuring from underground storage tanks captures subsurface risks to environmental features. “We sort of saw the 500 feet from the fuel dispenser as sort of the airborne point of source,” Robert said. Planning’s compromise — pumps for populated uses, tanks for aquatic/environmental features — won majority support.

Committee action and next steps

The committee approved the planning‑board amendments and forwarded ZTA 25‑06 to the full council with a 2–1 committee recommendation. Council staff advised that a Costco or similar existing high‑volume retailer at Wheaton would not automatically be eligible under the ZTA and would still have to satisfy the measurement and conditional‑use requirements.

The full council will consider the measure at a future session. The committee directed staff to carry the clarified language forward and noted continued community interest and public testimony will be likely at the council hearing.

“We sort of saw the 500 feet from the fuel dispenser as sort of the airborne point of source and that the queuing could be seen as also coming or they’re queuing up to get to that point,” Ben Robert, Montgomery Planning, said in explanation of the compromise measuring points.

Ending

With the committee’s clarification, county officials said the ZTA aims to make an existing separation standard administrable for permitting while preserving protections for schools, parks and sensitive environmental features. The full council will receive the committee recommendation and the amended text for consideration.
