Overview
MARROW QUARRY is a stormwater outfall located in Cane Hill, Arkansas, United States. It operates under the EPA NPDES MS4 permit framework for stormwater discharges.
MARROW QUARRY is a stormwater outfall facility situated at 16150 South Highway 45 in Cane Hill, Washington County, Arkansas. As a stormwater outfall, it serves as a discharge point for stormwater runoff from the surrounding area, which includes quarry operations classified under NAICS 212312 (Crushed and Broken Limestone Mining and Quarrying). The facility is operational and falls under the regulatory oversight of the United States Environmental Protection Agency's National Pollutant Discharge Elimination System (NPDES) program. Stormwater outfalls like MARROW QUARRY are typically subject to NPDES MS4 permits, which regulate discharges from municipal separate storm sewer systems. In Arkansas, the Arkansas Department of Energy and Environment - Division of Environmental Quality administers the NPDES program. The facility's industrial classification suggests it may also be subject to stormwater regulations for industrial activities, requiring compliance with stormwater pollution prevention plans (SWPPP) and best management practices (BMPs) to control pollutants in runoff. The environmental significance of MARROW QUARRY lies in its role in managing stormwater runoff from a quarry operation, which can contain sediment, heavy metals, and other pollutants. Proper management of this outfall helps protect local water bodies, such as the Illinois River watershed, from degradation. The facility's location in a rural area of Arkansas highlights the importance of stormwater controls in both urban and industrial settings to maintain water quality and ecosystem health.
Environmental context
The MARROW QUARRY stormwater outfall is located in the Ozark Highlands ecoregion of Arkansas, characterized by karst topography and sensitive aquatic ecosystems. Stormwater runoff from quarry operations can introduce sediment, metals, and turbidity into nearby streams, potentially impacting water quality in the Illinois River watershed, which is a focus of regional conservation efforts. Regulatory compliance with NPDES permits is critical to minimize these impacts and protect downstream water resources.
Frequently asked questions
MARROW QUARRY is located at 16150 South Highway 45 in Cane Hill, Washington County, Arkansas, United States.
MARROW QUARRY is a stormwater outfall facility that discharges stormwater runoff from a quarry operation classified under NAICS 212312 (Crushed and Broken Limestone Mining and Quarrying).
Stormwater outfalls in Arkansas are regulated under the EPA's NPDES MS4 permit program, administered by the Arkansas Department of Energy and Environment - Division of Environmental Quality. Industrial facilities may also require individual stormwater permits and must implement stormwater pollution prevention plans.
As a quarry operation, MARROW QUARRY likely employs best management practices (BMPs) such as sediment basins, silt fences, and vegetative buffers to control pollutants in stormwater runoff, in compliance with its NPDES permit requirements.
Stormwater runoff from quarries can carry sediment, heavy metals, and other pollutants that may degrade water quality in receiving streams. Proper management through BMPs and regulatory compliance helps protect aquatic ecosystems and downstream water resources.
