CENTRAL WELLAND RIVER WATERSHED PLANExpansion of Niagara Region‟sOrganic Deicing MaterialProgramMunicipal Road Salt ImpactStudy and Initiation of anOrganic Deicing MaterialProgram for sensitive areasPotential Contaminant Sourcesof Point Source PollutionIn Tow Path Drain subwatershed, 3 regional roads (Rice Road, Woodlawn Road and Niagara Street) traverseareas of medium groundwater vulnerability and significant groundwater recharge areas. Expansion of NiagaraRegion‟s Organic Deicing Material Program to include these regional roads is recommended to reducevulnerability of these areas to the negative impacts of road salt during winter maintenance practices.Through RMN‟s Salt Vulnerability Study (2005) the majority of the Central Welland River watershed has beenranked as having a moderately high vulnerability to road salt from regional roads for surface water, wetland andfish habitat features. However this study was not conducted on local municipal roads; therefore it is recommendedthat a similar study be completed by the respective municipalities to determine the impact of road salt applicationson municipal roads to surrounding features. Once complete, it is recommended that an organic deicing materialprogram be initiated, such as Regional Niagara‟s, for areas that have been identified as vulnerable to road saltfrom municipal roads. In this subwatershed, numerous municipal roads traverse areas of high and mediumvulnerability as well as significant groundwater recharge areas. It is recommended that the initiation of an organicde-icing material program be implemented in these areas.An inventory of potential contaminant sources and threats to water quality was identified as part of the objectivesfor the NPCA‟s Groundwater Study (2005). In Tow Path Drain subwatershed several of these points wereidentified; cemeteries, automotive/machinery, fuel storage, and potential PCB‟s. An updated inventory to confirmpotential contaminant sources and locations is recommended as well as further investigation into the possibleeffects these potential contaminants may have on surface water quality and aquatic habitat and whether or not acontaminant management plan is needed.168
