Residents living north and northwest of the DTG Landfill told the Yakima Regional Clean Air Agency board that crushing and repurposing operations are creating dust that is not being captured by current monitoring and permit enforcement.

"The computer generated calculation created in YRC A A's office does not produce realistically the true amount of dust emitted 5 days a week, 6AM to 6PM into the neighborhood and trails," said Carol DeGraves, a nearby resident, during the meeting's public-comment period. "And I might add that granite crushes till 9 or 10PM, which does not adhere to the permit."

DeGraves told the board the common modeling and the agency's calculations understate emissions because they do not account for day‑to‑day hours of operation, the number of trucks and containers, wind velocity and direction, site covering, constant machinery operation and public trail use around the site. She also relayed that, "from a past meeting, the director could not guarantee once a year actual visit," and urged the agency to consider an "elaborate monitoring system for the true air quality."

The board opened the meeting's public‑comment period for any matter relevant to the board and reminded speakers comments are limited to three minutes. The board did not adopt any formal action during public comment on the dust concerns, and no enforcement or monitoring changes were announced at the meeting.

Agency staff and board members discussed monitoring and permit work elsewhere on the agenda, but during the public‑comment portion the concerns remained a resident request for more frequent or more comprehensive air monitoring and for enforcement to ensure permit hours and activity limits are followed. Members did not commit to a specific inspection cadence or a new monitoring program at the meeting.

The issue remains in the citizen record; residents may follow up directly with agency staff as the board continues handling permit procedures and program work in future meetings.
