PART 1: INTRODUCTION
The purpose of this Stormwater Management Plan (SWMP) is to establish and define the means by which
the Town of Ranlo will comply with its National Pollutant Discharge Elimination System (NPDES)
Municipal Separate Storm Sewer System (MS4) Permit and the applicable provisions of the Clean Water
Act to meet the federal standard of reducing pollutants in stormwater runoff to the maximum extent
practicable.
This SWMP identifies the specific elements and minimum measures that the Town of Ranlo will develop,
implement, enforce, evaluate and report to the North Carolina Department of Environmental Quality
(NCDEQ) Division of Energy, Minerals and Land Resources (DEMLR) in order to comply with the MS4
Permit number NCS000417, as issued by NCDEQ. This permit covers activities associated with the
discharge of stormwater from the MS4 as owned and operated by the Town of Ranlo and located within
the corporate limits of the Town of Ranlo.
In preparing this SWMP, the Town of Ranlo has evaluated its MS4 and the permit requirements to
develop a comprehensive 5-year SWMP that will meet the community’s needs, address local water
quality issues and provide the minimum measures necessary to comply with the permit. The SWMP will
be evaluated and updated annually to ensure that the elements and minimum measures it contains
continue to adequately provide for permit compliance and the community’s needs.
Once the SWMP is approved by NCDEQ, all provisions contained and referenced in this SWMP, along
with any approved modifications of the SWMP, are incorporated by reference into the permit and become
enforceable parts of the permit.

The Town of Ranlo recognizes that the Lake Wylie TMDL 1995 Catawba River Basin Wide Water
Quality Management Plan points to a collaborative effort to deal with non-point sources of pollution in to
the South Fork River. The Town of Ranlo therefore has targeted certain industries and users with public
education and involvement BMPs to bring awareness and reform to improper practices such as the
overuse of fertilizers and herbicides, improper waste disposal at automobile repair shops, and other
household contributors such as home maintenance. As noted, all BMPs are related ot the reduction of
pollution and enhancement of water quality recovery.
3.6 Endangered and Threatened Species and Critical Habitat
Significant populations of threatened or endangered species and/or critical habitat are not identified
within the regulated MS4 urbanized area, as determined by a review of the Endangered and Threatened
Species and Species of Concern by County for North Carolina Map and Listed species believe to or
known to occur in North Carolina map as provided by the U.S. Fish and Wildlife Service. Of those
species listed, Table 4 summarizes the species that may be significantly impacted by the quality of surface
waters within their habitat.

3.8 Non-Stormwater Discharges
The water quality impacts of non-stormwater discharges have been evaluated by the Town of Ranlo as
summarized in Table 6 below. The unpermitted non-stormwater flows listed as incidental do not
significantly impact water quality. The Town of Ranlo has evaluated residential and charity car washing
and street washing for possible significant water quality impacts.
Street washing discharges are addressed under the Pavement Management Program in Part 10 of this
SWMP. The Division has not required that other non-stormwater flows be specifically controlled by the
Town of Ranlo
Wash water associated with car washing that does not contain detergents or does not discharge directly into
the MS4 is considered incidental. However, these types of non-stormwater discharges that do contain
detergents have been evaluated by the Town of Ranlo to determine whether they may significantly impact
water quality. The Town of Ranlo has evaluated the locations of where public works vehicles are cleaned
as well as where the Ranlo Volunteer Fire Department washes their vehicles and have determined that the
locations are sufficient for protecting water quality purposes. Residential and charity car washes offer
possible water quality impacts and the IDDE in Part 7 of this SWMP describes a methodology to investigate
further. Public Education and Outreach in Part 5 of this SWMP identifies the ways in which the Town of
Ranlo plans to educate target audiences about stormwater conscious car washing.

3.9 Target Pollutants and Sources
In addition to those target pollutants identified above, the Town of Ranlo is not aware of other significant
water quality issues within the permitted MS4 area.
Table 7 below summarizes the water quality pollutants identified throughout Part 3 of this SWMP, the
likely activities/sources/targeted audiences attributed to each pollutant and identifies the associated
SWMP program(s) that address each. In addition, the Town of Ranlo has evaluated schools, homeowners
and businesses as target audiences that are likely to have significant stormwater impacts.
Schools were selected as a target audience due to the opportunity to affect positive change through
education and involvement opportunities. Homeowners and businesses were identified as target
audiences because they are likely sources of non-point pollution through uniformed management
practices.
Schools: With the onset of COVID-19 and the increased cleaning of many businesses and schools,
the Town of Ranlo is becoming aware of increased levels of chemicals associated with cleaning products.
Whereas these increased levels have been identified and accounted for with the treatment of wastewater,
staff has begun to communicate to the schools concerning the potentiality of future impacts that this could
bring to the Town of Ranlo’s stormwater. The Town of Ranlo will utilize Part 5 of this SWMP as the
avenue to address this concern by reaching out to the school’s staff to identify their practices and evaluate
that to the IDDE of the SWMP.
Homeowners: Homeowners will be targeted with BMP information as it relates to pool cleaning,
landscape maintenance, paint practices, and vehicle maintenance. Part 5 of this SWMP describes BMP
flyers that have been created regarding these topics so that we may educate citizens to make better
decisions when conducting maintenance at their households.
Businesses: The food industry and auto repair and maintenance businesses will be targeted with BMP
information. This outreach is detailed in Part 5 of this SWMP and will include mailed flyers and follow-
up conversations with businesses regarding best management practices. The construction industry will
also be targeted with BMP flyers during the preconstruction permitting (Part 8).
