Surface Waters. Highway surface run-off discharges may contain soluble and insoluble pollutants that have accumulated on the carriageway following periods of dry weather. In storm events, these pollutants may be transported via the highway surface water drainage system and discharged to a receiving watercourse. In some circumstances, the pollutants in highway run-off may exert an acute and/or chronic impact on the chemical quality and ecological status of the receiving water. Although the Highways Agency has a right to discharge highway run-off, it has no right to pollute. The Environment Agency has a duty under the Water Resources Act 1991 to achieve water quality objectives in waters. There are powers to serve anti-pollution works notices to prevent or remedy pollution of controlled waters. To prevent pollution, the potential impact of discharges of run-off from the highways network must be properly assessed and appropriate pollution prevention measures put in place where unacceptable risk of pollution is identified. For existing trunk roads and motorways the Highways Agency has implemented a priority outfalls programme to consider existing discharges where a risk of pollution has been identified and will work with the Environment Agency to agree appropriate pollution prevention measures. For proposed new highway schemes, the Parties will work together to identify and gain an appreciation of the key constraints and potential consequences on the quality of surface waters and, where a risk of pollution is identified, agree reasonable mitigation measures which, on major highway schemes, will form part of the Environmental Impact Assessment. Key Commitments 1, 2, 3 and 14 Key Reference:
Surface Waters. 1. Field verification of seasonal wetlands will be verified by Ecology prior to the start of construction and impacts identified to wetlands or buffer areas shall be mitigated in accordance with this Agreement, the Revised MDNS, and the ASC.

Surface Waters. Any diminishment, destruction or diversion of surface water rights by Lessee shall only be to the extent reasonably necessary to Lessee's permitted uses of the Property under this Agreement; and, prior to such activity by Lessee, any diminishment, destruction or diversion of surface water rights shall be subject to: (a) a commitment from Lessee to provide a reasonably adequate replacement for such surface water rights or, (b) prior discussion and agreement with Owner as to the best means to mitigate loss of Owner's use of said surface water rights.
Surface Waters. Basic forms of potential adverse impact of the planned Works Contract 3D.3 on surface water were presented in Chapter 5.5. For the purpose of limiting those impacts Appendix 1 to the EMP implements mitigation measures to e.g.: • Limit the risk of polluting the water on the performance stage (e.g. items no. 5, 6, 13, 14, 15, 26, 27, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 84, 85, 86, 87, 88); • Limit the risk of polluting the water on the operational stage (e.g. items no. 59); • Limit the risk of adverse impact on biological elements of the water quality (e.g. items no. 47, 61, 62, 63, 64, 65).
Surface Waters. The Board may regulate, conserve and control the use of storm and surface water within the North Xxxxxx River Watershed.
Surface Waters. The impact factors of the Works Contract 3D.3 on the elements of surface water quality will be mainly related to the performed works of demolition and strengthening of the bottom and slopes of ditches. Typical negative impacts associated with renovation, upkeeping or maintenance works for the project under consideration include: • disturbance of species living in ditches or in their immediate vicinity; • destruction or disturbance of habitats on the banks of ditches (direct destruction, removal of trees and bushes, crushing, backfilling); • periodic sludge as a result of works. Other factors that may have a negative impact on the water environment will be works related to the transformation of fragments of the structure of ditches’ banks, directly in their initial and final sections, as well as the transformation of morphology through the relocation of fragments if ditches, in order to ensure the proper functioning of embankment equipment. The performance of construction works is associated with the potential contamination of the soil and water environment as a result of e.g. breakdown of construction machinery or vehicles causing leakage of oil derivatives, etc. The contractor is obliged to conduct ongoing monitoring of water quality in order to prevent the possibility of exceeding the permissible levels of pollution. Notwithstanding the foregoing, carrying out works in riverbeds or channels, as well as on the banks of waters must comply with World Bank guidelines contained in the document “Environmental, Health and Safety Guidelines for Ports, Harbors, and Terminals”21 The works provided for in the Works Contract 3D.3 are not related to the permanent abstraction of water (surface or underground water), introduction of sewage to water or ground, substances particularly harmful to the aquatic environment (to water, ground or sewage facilities). The intervention in the riverbed of the River Łęg will only take place if works are carried out related to the strengthening of the slope of the ditches that flow into the river. These works will not affect the ecological condition/potential of BSWs. The implementation of the Works Contract 3D.3 will not change the magnitude and dynamics of water flows in the river, nor do they affect the frequency and extent of flooding of river waters into the areas of the current embanked area. The above-mentioned factors will not affect the elements of the ecological status of BSWs, i.e. biological, hydromorphological and physic...
Surface Waters. The implementation site of the Works Contract 3D.3 is located in the basin of the central Vistula River, in the area of the mouth of the Łęg River. The modernized sections of the embankments are located between 25 m and about 250 m from the riverbed of the Łęg River (depending on the fragment of the embankment) and about 225 m from the riverbed of the Vistula River in the initial section (km 0+000).
