4.3 Water Resources

  • 16 private wells within 150 feet of construction work area in Lancaster Co (4-39)
  • Because surveys along the project route have not yet been completed there is a potential that other private water supply wells and springs may yet be identified within 150 construction work areas. (4-41)- (how can an eis not have all of the information like this- in its proposal-- how can FERC make a decision if they don't have the full picture?)
  • Transco would minimize the potential for impacts associated with encountering acid mine and mine pool drainages by implementing the measure in its Abandoned Mine Investigation and Mitigation Plan- including sealing openings, and/or diverting discharges. (4-42)
  • Construction activities are not likely to significantly affect groundwater resources because the maj of construction would involve shallow tem localized excavation-Transco would restore the ground surface as closely as practicable to original contours and revegetate the right of way to ensure restoration... (4-44) (So many of these terms are so ambiguous... "as closely as practicable"- and what exactly does that mean? and who decided that this non-statement is enough to protect the health and safety of the residents around? Who determines that this is enough to ensure no significant environmental impact?)
  • Transco proposes to cross two waterbodies using HDD method near areas of known karst along cpl south- Conestoga River in two locations- (4-45)
  • unconfined aquifers and shallow groundwater areas could be vulnerable to contamination caused by inadvertent surface spills of hazardous materials used during construction. Transco has a Spill Plan (4-45) (so have no fear?)
  • Blasting-Transco identified several areas along the proposed pipeline ROW where blasting may be required for construction. This could affect groundwater quality by temporarily affecting yields of springs and/or wells in close proximity- Transco would minimize impacts- would obtain all necessary permits. All effects should dissipate shortly (4-46)
  • Transco has committed to testing (water) prior to and after construction, subject to landowner permission. (does this mean they are going to ask each landowner and do this voluntarily, or must the landowner ask- and will the ask be honored even if it isn't in the contract?- also- what about beyond 150 feet- water aquifers and water sources can be affected at a greater distance- how is Transco held responsible to people who have their water affected beyond this designated distance?) (4-46)
  • Contaminated ground water could result from AMD and mine pool discharges. Transco developed mitigation measures to minimize this. (4-46).
  • Within 30 days of placing the project facilities in service, Transco should file with Sec a report describing any complaints regarding water well yield or quality- and how each complaint was resolved. (4-46)
  • Conclusion- no long term impacts on groundwater are anticipated from construction and operation of the Project because disturbances would be temorary-(4-47)
  • The pipeline facilities would cross nine watersheds or drainage basins. (4-47)
  • Project involves 331 waterbody crossings (311 associated with pipeline, 20 involving access roads) 207 perennial waterbodies, 79 intermittent waterbodies, 39 ephermral waterbodies, 6 ponds-- in addition- 23 perennial waterbodies, 18 intermittent waterbodies, 6 ephemeral waterbodies by access roads. (4-48)
  • 4 potable surface water intakes within 3 miles downstream of waterbody crossings were identified. (4-49)
  • Prior to end of the draft eis comment period- Transco should file with the Sec proposed mitigation measures Transco would implement to protect all Zone A source water protection areas. (4-51)
  • Selected waterbodies are further classified as Exceptional Value or High Quality and given special protection- (4-52)
  • 8 bodies of water at High Quality level crossed for CPLS- Tucquan Creek would be Dam and Pump crossing- (4-55)
  • Transco proposes to use a wet open cut crossing method at 8 waterbodies. (4-58)
  • Transco proposes to use a dry crossing method at 274 waterbodies. (4-58)
  • Transco would use a trenchless crossing method at 8 waterbodies. (4-58)
  • Some blasting may be required along the project route to allow excavation of the trench- If in-water blasting is required Transco would develop a site specific blasting plan for each crossing. (4-58) (This the is plan-the deis- if blasting is required to cross waterbodies- it should be in here- where and how and how much damage...
  • Transco would use HDD (Horizontal Directional Drilling) method... Susquehanna and Conestoga Rivers- water from waterbody being crossed would be used to create the drilling mud- estimate that 286,065 gallons water required at Susq. R crossing, and 275,565 gal at conestoga river crossing. (4-59) (What is done with the mud/slurry waste of the drilling? How is it disposed of without negatively affecting the life of the waterbody being crossed?)
  • Hyrdostatic testing- verify structural integrity of pipeline with water- 8 hours of testing- filling pipeline with water, pressurizing it and then checking for pressure losses due to pipeline leakage- 61 million gallons of water from surface waterbodies and municipal sources. Water would be discharged into well-vegetated upland locations or into receiving waters using energy dissipation devices. (4-59)
  • * lancaster- 8,566,090 gallons from Pequea Creek (2,000 gpm) 513,076 gallons from Conestoga River 4,843,745 gallons from Chickies Creek (2000 gpm) (4-60- for rest of stats) 
  • Pipeline construction activities could affect surface waters by: modification of aquatic habitat, increased runoff and rate of in-stream sediment loading, turbidity, decreased dissolved oxygen concentrations, releases of chemical and nutrient pollutants from sdeiments, thermal effects, modification of reparian areas, into of chem contaminants such as fuel and lubricants. (4-61)(I wonder what possibilities there would have to be in order for this to be considered a significant impact to the environment?)
  • Transco would implement several mitigation measures within floodplains to minimize potential effects from flood events- including: installing and maintaining erosion and sediment control structures, restoring floodplain contours and waterbody banks to their preconstruction condition, and conducting post construction monitoring to ensure successful revegetation. (4-63) (Who ensures this takes place? When williams was installing rock springs- NONE OF these things were in place for the first 3 days of construction- and were only put in place because neighbors took pictures and reported them to authorities... Transco promising these things has not equated to them actually happening in the past- so who is going to be sure all of this actually happens?)
  • Transco would minimize effects at wet crossings by: limiting operation of equipment in water to that needed to construct the crossing, completing construction activities within 24-48 hours, except for areas that require blasting or other rock-breaking measures, requiring bank stabilization and reestablishment of bed and bank contours, limiting post-construction maintenance of vegetated buffer strips adjacent to streams, implementing Transco's Spill Plan. (4-63) (Again, seriously?- who decides what is "needed"? We have already heard from Transco that much of the bedrock will need to be blasted- so what is the worst case scenario in those instances? and what is the plan in those instances? - and who keeps the installers accountable for all of this?)
  • Public Water Supply Watersheds and Source Water Protection Areas-Transco would implement measures to avoid or minimize effects on water operators (4-65) (However all of the water sources for drinking water is well - water- what kind of plan does Williams/Transco have to inform ALL of the well water landowners along the line in case of accident? and how will they propose to take care of people's water supply once it is damaged by Transco, and unusable?)
  • If blasting in waterbodies is required, there is a potential for permanent alterations of stream channels. (4-68)
  • Extra workspace within 50 feet of waterbodies- but some conditions don't allow for this - (4-68)
  • No long-term effects on surface waters are anticipated as a result of construction and operation of the Project.
