AYRSHIRE ELECTRONICS OF ARKANSAS LLC, Fayetteville

Overview

AYRSHIRE ELECTRONICS OF ARKANSAS LLC DBA KEYTRONICEMS operates a stormwater outfall in Fayetteville, Arkansas, managing industrial stormwater discharges under US EPA NPDES MS4 regulations.

AYRSHIRE ELECTRONICS OF ARKANSAS LLC DBA KEYTRONICEMS is an industrial facility located at 3660 S SCHOOL ST in Fayetteville, Washington County, Arkansas. The facility operates a stormwater outfall, managing stormwater runoff from its industrial activities. As a stormwater outfall, it is subject to the US EPA's National Pollutant Discharge Elimination System (NPDES) permitting program, specifically under the Multi-Sector General Permit (MSGP) for industrial stormwater discharges. The facility's operations span multiple NAICS codes including 332112 (Nonferrous Forging), 334118 (Computer Terminal Manufacturing), 334412 (Bare Printed Circuit Board Manufacturing), 335931 (Current-Carrying Wiring Device Manufacturing), 335990 (All Other Electrical Equipment Manufacturing), 335999 (All Other Miscellaneous Electrical Equipment Manufacturing), 423610 (Electrical Apparatus and Equipment, Wiring Supplies, and Related Equipment Merchant Wholesalers), and 562910 (Remediation Services). These diverse industrial activities generate stormwater runoff that must be managed to prevent pollution of local waterways. In Arkansas, stormwater discharges from industrial facilities are regulated under the Clean Water Act, with the Arkansas Department of Energy and Environment - Division of Environmental Quality (DEQ) serving as the authorized permitting authority. The facility must implement a Stormwater Pollution Prevention Plan (SWPPP) and comply with effluent limits and monitoring requirements to protect water quality in receiving waters, which ultimately drain to the Arkansas River basin.

Environmental context

Fayetteville is located in the Ozark Mountains region, characterized by karst topography with limestone bedrock, which makes groundwater particularly vulnerable to contamination from stormwater runoff. The area receives approximately 48 inches of annual rainfall, creating significant stormwater volumes. Industrial facilities like this one must carefully manage runoff to prevent pollutants such as heavy metals, oils, and sediments from entering sensitive karst aquifers and surface waters, including the Illinois River and Lake Fayetteville, which are used for recreation and drinking water supply.
