2.2.2.3 Access Roads <br />Access roads to and from existing well pads are unpaved, often graveled, and cover a wide area <br />on the NSI Lease. The only hazardous materials that could potentially be present and negatively <br />affect stormwater discharge would be leaked fuels /fluids from either the heavy equipment used <br />to initially construct the access road, or from vehicles that currently use the access roads to get to <br />and from the existing well pads. <br />Heavy equipment used to construct access roads are maintained regularly to prevent fluid leaks. <br />The access roads will be inspected for leaks immediately after access road construction and <br />monthly for those roads that are actively used. Access roads that are infrequently used will be <br />inspected every six months. Identified leaks or spills will be absorbed as necessary with <br />absorbents and removed via shovel for cleanup purposes. <br />In order to mitigate erosion of the access roads and to provide runoff control, all access roads <br />will be crowned and ditched along the trace of the roads. Periodic inspection of the roads will <br />determine erosional extent and effectiveness of the crowning and ditching. Other BMPs, such as <br />straw bales or berms, will be implemented as necessary to limit erosion. <br />2.3 Sampling Information <br />NSI has no historical stormwater discharge sampling data. For the purposes of stormwater <br />discharge monitoring, NSI is a designated Sand and Gravel production operation and is not <br />required to do so. No future stormwater discharge data is anticipated to be collected. <br />2.4 Preventative Maintenance <br />For the identification of machinery, equipment, and areas that are to be inspected and the <br />schedule for such inspections and maintenance, please see the descriptions of the BMPs for each <br />site - specific area in Section 2.2. A record of all inspections, whether weekly or semi - annually, <br />whether in relation to the processing plant or well field, will be contained within a log book that <br />is to be kept and maintained in the NSI processing plant with the SWMP Administrator. This <br />record will include the date of inspection, the site or equipment inspected, a description of the <br />facility /equipment, any problems noted, and a description of any remedial actions taken. <br />Additionally, the log book will also include a spreadsheet detailing the need for <br />spare /replacement parts for NSI operations, including, but not limited to, piping, liner, fencing, <br />machinery, and mechanical equipment. The date, description, and quantity of these materials <br />ordered will be recorded in the log book. <br />Daub & Associates, Inc. NSI 2011 SWMP <br />Page 10 <br />
