Port of Morrow Farms 3-4 Winter Storage
|
The Port of Morrow, located along the Columbia River in Boardman, Oregon collects, treats, and land applies wastewater from industrial businesses in the region. Under the conditions of the Water Pollution Control Facilities (WPCF) Permit #102325 Modification #1, the Port is authorized to land apply the wastewater to a series of five farms covering approximately 10,000 acres of agricultural land.
The Port’s Permit is classified as a Tier II Industrial WPCF which allows it to accept wastewater from 17 industrial sources and requires the coordination of a series of lagoons, pump stations, and pipelines that collect, store, treat, and transport the wastewater. Recycled wastewater is land applied to five separate farms that are generally separated into two clusters, with Farms 1, 2 and 3 located adjacent to the Port while Farms 4 and 5 are located approximately eight miles to the southeast approaching Highway 207. The Port is required to cease land application of wastewater during the non-growing season, defined as November through February, except as provided by the Oregon Department of Environmental Quality (DEQ) for beneficial uses with treated effluent. The Port needs more storage capacity for treated industrial wastewater to be stored over the non-growing winter season. Two locations have been identified by the Port for storage lagoons that will each require approximately 750 million gallons (MG) of storage capacity. The first lagoon is at Farm 3 and will occupy approximately 84 Acres of land with an average water depth of over 27 feet. The Farm 3 lagoon is proposed to be located on what is currently one half of an irrigation pivot circle of agricultural land. The proposed Farm 3 lagoon site is abutted to the south by an overhead power transmission line corridor and will need to be coordinated with the Bonneville Power Administration to ensure the appropriate power facility setbacks are considered in the design of the lagoon. The second lagoon is adjacent to the existing storage lagoons at Farm 4 and will occupy approximately 56 acres with an average water depth of 41 feet. The proposed Farm 4 lagoon is surrounded by the existing Farm 4 storage lagoons to the south, a center-pivot irrigation circle to the east, and agricultural access road to the North and West. There are also overhead power facilities to the Northwest of the proposed Farm 4 lagoon site requiring coordination with the power utility to ensure sufficient clearance is provided between the power facilities and the proposed lagoon. The Farm 4 lagoon will also include additional coordination relating to site drainage, especially in consideration of the existing adjacent lagoon and associated drainage facilities. The new storage lagoons will need to be commissioned and ready to fill by November 1, 2025 due to a nitrate restriction that DEQ has placed on the Port for the winter of 2025. This project, when completed, will satisfy this requirement. The project will include the professional services required to successfully plan, permit, design, construct, and commission two, 750 MG storage lagoons on an expedited schedule. The team that AQUA has assembled for this storage lagoon project is well equipped and very experienced in addressing the required scope of services. |
