Stornnvater tMana Bement Prograin Plan � 1, m ' 7.1 Public Education and Outreach on Storm Water lnilmets 7.1.1 13N11' Summary Table 7.1.1 describes the activities the City will undertake to meet the State's public education and outreach requirements. ' 7.1.2 The City has a growing number of commercial and industrial developments, especially in areas that flow into receiving streams. "Therefore, business and industry owners will be the primary target audience for the public education component of the City's stornwater program. Residential property owners will also receive educational materials on how stormwater impacts can be minimized. ' 7.1.3 No receiving streams in the City's jurisdiction are identified by the state for having any specific pollution issues. As development increases, ' however, sediment will be the major pollutant targeted by the stormwater program. ' 7.1.4 A combination of brochures and public workshops will be used to distribute information about stormwater to property owners. Materials will be directly mailed to business and industry owners. ' 7.1.5 The City Planner developed a draft outreach program based on research from other existing programs. In general, the BMPs will focus oil explaining what homeowners and business owners can do to reduce pollutant loading and minimize stormwater volume. Individual BMPs were selected that would be effective in communicating general ' stormwater education to the public, and that could utilize existing City resources or programs in doing so. ' 7.1.6 The success of this particular minimum measure will be evaluated based oil the following: the number of stormwater educational materials distributed to homeowners; the number of City events where educational ' materials and displays were available; the number of business and industries receiving stormwater materials; and the number of people attending stormwater workshops. ' 7.2 Public Involvement and Participation I 7.2.1 I MII Summary Table 7.2.1 describes the activities the City will undertake to meet the Suite's public involvcnient and participation requtrcnlCnta. 7.2.2 While Clarellwnt is ❑ shall, rural Cominiulity, with a relatively hOIl1OgC11OLIS poplllatiOn, tI1Ci'C ❑1'C it grOwing 11L1111bC1' 01 C0111111C1'Cla1 and industrial developnlcnts. The locus of this component of the City's 1 7.3 I Comprehensive Stormw°ater Management Program Report. stormwater program will be involving primarily business and industry leaders in planning, oversight, and community involvement activities. However, homeowners will also be included. 7.2.3 An advertised public hearing; before the City Council was held to receive public comment on the City's stormwater program prior to its official , adaptation. As an Integral component to the public Involvement requirement, the City will establish a citizen stormwater committee that ' will help staff evaluate the effectiveness of the City's program over time and suggest changes to the program as deemed necessary. , 7.2.4 Because Claremont is a relatively small city, a limited number of organized civic and community groups exist. For this reason, it will be difficult to find individuals and organizations willing to actively participate in activities such as storm drain stenciling and adopt -a -stream ' programs. One of the roles of the stormwater committee will be to identify individuals over time in the community with expertise in various ' stormwater topics willing to educate others about stonmwater impacts, as well as identify organizations willing to participate in stormwater-related activities and projects. ' 7.2.5 The success of this particular minimum measure will be evaluated based on the following. the number of meetings held by the citizen stormwater ' committee and the number of phone calls received by the City reporting water quality violations or expressing concerns regarding water quality. Illicit Discharge Detection and Elimination ' 7.3.1 BMP Summary Table 7.3.1 describes the activities the City will undertake , to meet the State's illicit discharge detection and elimination requirements. 7.3.2 A storm drain map for the City's planning area will be developed by the ' end of Year II using GPS and GIS technology. While the GPS technology employed will not be survey grade, the accuracy will be more than sufficient to use the map(s) created to assist the City with later identifying ' dry weather flows and other suspicious discharges for in-depth inspections and monitoring and potcntial elimination. Besides hydrography and outfall information, the location of roads and businesses in the City will also be placed on these maps. The developlment, analysis and storage of this information in a GIS-data base will facilitate the regular updating of t these maps on an anticipated five-year interval. 7.:_3 The City will adopt a Ste►rm++ater t��tanagement Ordinance. Tills ordinance will prohibit the discharge of matcrials to streams that are not eared In stormwater or covered under a NPDES permit issued the North Carolina Department of Health and NLitUral ReSources.

Over time, as educational outreach efforts are implemented, calls from citizens and businesses may help identify other priority areas. 7.3.5.2 Streams will be walked annually during dry weather periods to look for nonstormwater flows. Suspicious appearing discharges will be visually inspected as suggested by US EPA (see Attachment 4 - EPA Storm Water Management Fact Sheet). ' 7.3.5.3 A letter from the City will be sent to the individual or business notifying them that they are in violation of the City's Storniwater Management Ordinance. Emphasis will be placed ' on obtaining voluntary compliance initially. However, if the violator does not take action to comply with the City's ordinance, the City will take appropriate legal action to ensure ' removal of the illicit discharge. 7.3.5.4 A major responsibility of the City's Citizen Storniwater Committee will be to evaluate the effectiveness of all program elements and suggest changes where appropriate.

September 1999 Agency E PA Storm Water Management Fact Sheet Visual Inspection DESCRIPTION ADVANTAGES AND DISADVANTAGES Visual inspection is a Best Management Practice (BMP) in which members of a Storm Water Pollution Prevention Team visually examine material storage and outdoor processing areas, the storm water discharges from such areas, and the environment in the vicinity of the discharges, to identify contaminated runoff and its possible sources. In a visiial inspection, storm water runoff may be examined for the presence of floating and suspended materials, oil and grease, discoloration, turbidity, odor, or foam; anti storage areas may be inspected for leaks from containers, discolorations on the storage area floor, or other indications of a potential for pollutants to contaminate storm water runoff_ Visual inspections may indicate the need to modify a facility to reduce the risk of contaminating runoff. APPLICABILITY The U.S. EPA has recognized visual inspection as a baseline BN/IP for over 10 years. Its implementation, however, has been sporadic. Implementation may increase as more Iacilitics develop Storm Water Pollution Prevention Plans_ Iniptctncntatican triatV also incrcrtse as Iacility managc.nicnt rc( cognizus visual inshectiml to be cl"fCctivc both in protectiifa %v llcr cltutlity and in rcdticiiig cr>, ts. Visual inspections are an effective way to identify a variety of problems. Correcting these problems can improve the water quality of the receiving water. Limitations associated with visual inspections include the following: • Visual inspections arc effective only for those areas clearly visible to the human eye. • The inspections need to be perfonned by qualified personnel. • To be effective, inspectiois must be carried out routinely. This requires a corporate commitment to implementing them, • inspectors need to be properly motivated to perform a thorough visual inspection. KEY PROGRAM COMPONENTS Visual inspections for signs of storm water contamination should be performed routinely. Flows should be observed during dry periods to determine the presence of any stains, sludge, odors, and other abnormal conditions. Visual iushccti0ns should atlsu bu trutcic att ;ill st0rrti water discl7argc catitict ltic"tholis clt.u-iva 111e lirsl I estir ofa storm event, once runoff has reached its tnaxirmun1 IlMV rite;. Inspcctorsshciul{I examine; the dischar"c li)r the presuncu of Iloatill" and stislaeiided materials, oil acid gre;ise, {11sc:olorali0ti, IL.trbidiIy, foatri, car odor. Inspection frequency interval may be determined by the storm water d1sclrargc permit, by storm frequency, or by the potential risk from the site. Inspections should be made at least once a nionth in areas with frequent storms; inspections may be less frequent where storks are less frequent. Finally, inspection frequency may be based in part on the history of previous spills and leaks. Experienced personnel should evaluate the causes of previous accidents, assess the risks for future accidents, and determine an inspection schedule based on these risks. Proper records of inspection results must be kept. The record for each inspection should include the date of the inspection, the names of the personnel who performed the inspection, and their observations. Visual inspections of a facility should focus on the following key areas: • Storage facilities. • Transfer pipelines. • Loading and unloading areas. • Pipes, pumps, valves, and fittings. • Tanks (including internal and external inspection of the tank for corrosion and inspection of its support or foundation for deterioration). • Primary or secondary containment facilities • Shipping containers. In addition, a visual inspection should include assessing the integrity of the storm water collection system; checking for leaks, seepage, and overflows from sludge and Wastc disposal sites; and ensuring that dry chemicals and dust from industrial arc�7s is not exposed to wind or other'Acmcots Illm nrry move them into the runoll'. IMPLEMENTATION A visual inspection BMP program should be incorporated into every storm water discharger's record keeping and internal reporting structure. Outfall flow rates and the presence of oil sheens, floatables, coarse solids, color, and odors will probably be the most useful indicators of potential problems. Specific parameters to look for in completing a visual inspection include the following: • Odor: Discharge odors can vary widely. Some may indicate the source of contamination. Industrial discharges may smell like a particular spoiled product, oil, gasoline, a specific chemical, or a solvent. For example, the decomposition of organic wastes in a discharge will release sulfide compounds, creating an intense smell of rotten eggs. Significant sanitary wastewater contributions will also cause pronounced and distinctive odors. Color: Color may indicate inappropriate discharges, especially from industrial sources. Industrial discharges may be any color. Dark colors, such as brown, gray, or black, are most common. For instance, flow contaminated by meat processing industries is usually a deep reddish -brown. Paper mill wastes (plating -mill wastes) are often yellow. Wash water from cement and stone working plants can cause cloudy discharges. Contamination from industrial areas may come from process waters (slug or continuous discharges); from equipment and work area wash water discharged to floor drains; or from spills washed into storm drains. Turbidity:'hirbidity is often affected by the degree of gross contamination. Industrial flows can be cloddy (moderatcly turbid) or c�lhaquc (hi!�ltly turbid). Ultdiluted industrial discharges, such as those corning foil; Conti nual Ilow sources or itttcrntitlent spills, arc often highly turbid. Sanitary w,0C%vatcr is also often cloudy in nature, I Attachment 4 1 ' I• loatable matter: A contarniinatcd flow may also contain floatablc solids or liquids. Identifying floatables can aid in finding the source of the contamination, because these substances are usually direct products or byproducts of the rinanufacturing process or the srinitary system. Examples of lloata.bles ol- industrial origin are aninial fats, spoiled food products, oils, plant parts, solvents, sawdust, foams, packing materials, and fuel. Deposits and Stains: Deposits and stains (residues) are any type of coating that remains after a non -storm water discharge has ceased. Deposits or stains usually are of a dark color and usually cover the area surrounding the storm water discharge. They often contain fragments of floatable substances, and, at times, take the form of crystalline or amorphous powder. For example, contamination from leather tanneries often produces grayish -black deposits containing fragments of animal flesh and hair. Another characteristic example is the coating of white crystalline powder formed on sewer outfalls by nitrogenous fertilizer wastes. Vegetation: Storm water discharges often affect surrounding vegetation. Industrial pollutants often cause a substantial alteration in the chemical composition and pH of the discharge water, which can affect plant growth even when the source of cointanlination is intermittent. For example, nutrients fronn various food product wastes increase plant. growth. In contrast, the discharge of chemical dyes and inorganic pigments from textile mills may decrease vegetation, as these discharges are often very acidic. In either case, even when the pollution source is gone, the vegetation surrounding. tile discharge wit] colitillue io show the effects ol, the crrrlt�snninaiion. It order to accllratcly jifthe vegctatioll sini-rounding a discharge is ni�rntal, the Obsci-vel. must LA-C into accolilli recent wcathcr conditions, as well as the tillic of year. 111crl:aSCd or inhibited plant growth near storm water discharges, as well as dead and decaying plants, is often a sign of pollution. However, it is important to distinguish whether plant damage is caused by contaminadon or by the physical effects of increased ilows, such as scour. This Carl be done by chemically analyzing the flow or by confirming its source through additionai visual inspections. Stnlctural Damage: Structural damage is also a sign of industrial discharge contamination. Cracked or deteriorated concrete or peeling surface. paint at an outfail usually indicates the presence of severely contaminated discharges. Contaminants causing this type of damage are usually very acidic or basic and are usually of industrial origin. For instance, discharges from primary metal industries may cause structural damage because their batch dumps are highly acidic. The effectiveness visual inspections in reducing storm water runoffcontamination is highly variable and dependent upon site -specific parameters. These factors include inspectors' motivation level, the types of industrial activity occurring at the facility, and the facility's maintenance procedures. Because familiarity with facility operations is essential in performing effective visual inspections, the inspections should be assigned to qualified staff such as maintenance personnel or environmental engineers. Figure 1 provides a sample visual evaluation worksheet that can be used to record the results of the inspections. COSTS Costs forperformingthe visual inspection Moil' are minimal and consist of direct labor and overhead costs for staff hours spent on training, planning inspections, inspecting, and completing follow tip activities. Annual costs can be Cstimated using the example in Table I. Flgrnc 2 c<tn he used as a worksheet to calculate tiic cstilmitcil annual cost for inipicinenting a visual inspection program.
