CreekBACKGROUND
Weir Minerals NA SLC - Rubber Engineering (WMRE) is a molded rubber products manufacturer located in Salt Lake City, Utah with Standard Industrial Classification Code 3069 for rubber
manufacturing. The WMRE manufacturing plant has been in service for over 50 years and processes 11,000-13,700 pounds of rubber products per day, on average. The wastewater discharge
from the WMRE facility consists of both contact and non-contact cooling water, which are used to control temperature in the manufacturing of rubber products. WMRE uses municipal culinary
water to maintain constant temperatures (usually warmer than ambient to increase the malleable characteristics of rubber) while manufacturing rubber parts. Some rubber parts are heated
with the intent to cure, in pressurized autoclaves with steam (contact water) during which some of the steam condenses and is discharged. After the curing process is completed, contact
water is used to cool the rubber parts in the autoclave before it is opened. Non-contact water flows through the jackets enveloping processes (warming the rubber) while shaping it in
presses, extruders, and mills. About 8,000 gallons per day (gpd) of contact cooling water is used in the autoclaves, which flows to an internal discharge point (Outfall 002), which then
flows to the primary WMRE discharge via Outfall 001. The non-contact process water flow is approximately 100,000 gpd and flows directlyto discharge point Outfall 001. This permit will
once again authorize the wastewater discharges from WMRE during the next 5 years as appropriate. For additional information, please refer to the draft Permit and fact sheet documents.PUBLIC
