FERNDALE – Petrogas Ferndale Storage Terminal is seeking a permitting change so it can use two refurbished engines for back-up compression at its propane and butane storage and distribution operation.
In May 2016, Petrogas received an Order of Approval to Construct permit from the Northwest Clean Air Agency (NWCAA) so it could install two new, cleaner-burning gas-fired compressor engines at the terminal at 4100 Unick Road. Petrogas originally planned to remove the old compressor engines, but instead refurbished them.
The permit revision Petrogas is requesting would allow the refurbished engines to be used as back-ups in case of emergency and during maintenance on the new primary engines. The original air permit considered reductions of toxic air emissions from decommissioning the old engines. Now that Petrogas proposes to retain the old engines on-site with the new engines, those toxic reductions can no longer be applied and Petrogas must demonstrate that it won’t exceed state standards for toxic impacts.
NWCAA’s preliminary determination finds that the project would have no adverse impacts to ambient air quality for toxic air pollutants and will comply with all applicable local, state, and federal air quality regulations.
The public can comment on the proposed revised permit through Sept. 6. NWCAA will hold a public hearing on the permit revision on Sept. 5 at the Ferndale Public Library, 2125 Main St. An open house will begin at 6 p.m., followed by the public hearing at 6:30 p.m.
