Tipping building to help Kingston compost business control odors

Kitsap County does have an application from DTG Enterprises of Mill Creek to reinstall a tipping building at Olympic Organics in Kingston.

The building has been gone for over a decade, but apparently without government approval from agencies that oversee such operations. A tipping building helps control odor from such operations.

So Puget Sound Clean Air Agency required Olympic Organics to reinstall one as it had required the business to have one from the start.

The Kitsap County Building Department has had the application for months. But through a public records request, it denied even receiving an application. County Commissioner Christine Rolfes stepped in to help the Kitsap Daily News obtain the document.

An email from DTG to the PSCAA says it hoped to get county approval in April and start building so it could be completed in a few months.

The PSCAA violation notice says all compostable waste material brought on site shall be deposited completely inside the tipping building until processed. It adds the facility shall install and operate a fine water mist system on any wood grinder to control dust.

The permit application responds to inquiries from the county Building Department and fire marshal.

It says the building is temporary storage for feedstock for the composting operation, which consists mostly of green organics such as leaves, branches and grass clippings with minor amounts of food waste. The structure needs to have a roof and walls to contain odors.

Feedstock will be trucked to the building and dumped on the floor for storage. After being sorted, it will be transported by wheeled bucket to various onsite aerated static piles for composting. That type of treatment is enough at some sites statewide, but since PSCAA required the tipping building from the start it needed to be reinstalled.

Hooped structures with metal-steel frames and fabric roofs are commonly used for tipping buildings worldwide because they are a cost-effective solution for containing odors, the DTG application says.

The permit application includes dozens of pages detailing the tipping building and how it would be safe during an earthquake, snow or wind event. It says it could withstand up to 92-mile-per-hour winds, but even then it would only damage the fabric structure, which could be replaced. For snow, it’s 25 pounds per square foot. It says it meets the 20-foot front zoning setback and 20-foot access for fire vehicles.

Once approved there will be five required inspections for the permit.
