INFORMATION/BACKGROUND
The City of Denton owns and operates a 252-acre Type I Municipal Solid Waste (MSW) landfill which
disposes of an average of 1,094 tons per day of MSW as reported by the City’s Paradigm system. The
landfill site is co-located on a larger City-owned tract of land that houses the City’s Wastewater Treatment
plant and a composting facility that composts dewatered wastewater treatment plant sludge (bio-solids) and
wood waste. All of these facilities are potential sources of odors.
Under the Texas Municipal Solid Waste regulations, 30 Texas Administrative Code 330.149, the issued
Texas Commission of Environmental Quality (TCEQ) permit 1590B and the 1590B Settlement Agreement
the facility is required to have an odor management plan. The City worked to take a proactive role in
addressing odor complaints and reducing or eliminating the source of odor generation. Implementation of
best management practices at the facilities has reduced the frequency of odor complaints but during certain
periods of the year, the prevailing winds often change to a direction that blows odors to the more populated
areas. During these periods, the Landfill operators are on the lookout for waste that characteristically may
produce an odor (such as sludge, animal carcasses, and wet restaurant waste), so they can immediately bury
the potentially odiferous or noxious waste. Staff routinely utilizes odor control chemicals to prevent odors
from migrating beyond the permit boundary. The landfill currently has a GOC QuikAir Vapor Odor System
with 3000’ of piping installed along the east side and south end of the landfill property that is in operation
24/7 to help neutralize odors before leaving the site as the last line of defense. The City also uses AiroPure
an odor destructive reagent mixed in the water truck to actively spray around the site as needed to help
neutralize various noxious odors before they can have a chance to leave the site causing an odor complaint.
