4.2 Soils

  • CPL South (CPLS) - 126.3 miles in length, 61.8 highly erodible because of water, 77.3 % prime farmland, 92.9% hard shallow bedrock, and 17.4% soft shallow bedrock, 62.5% revegetation concerns. (4-26)
  • Erosion is a continuing natural process that can be accelerated by human disturbance- soils most susceptible to erosion by water are typified by bare or sparse vegetation cover, non-cohesive soil particles with low infiltration rates, and moderate to steep slopes. (4-26) (so let's create a row with little vegetation for further erosion)
  • Prime Farmland-The fact that a particular soil is considered prime farmland does not mean that it is currently in agricultural use: some prime farmland soils may be in Prime farmland may be in forested, open or residential areas.
  • 106 miles of the soils along the proposed line segments are considered prime farmland- 89.9 miles of these prime farmland soils are active agricultural land. (4-27)
  • Compaction potential- construction equipment traveling over wet soils could disrupt soil structure, reduce pore space, soil texture- 19.1 miles of soils along line are soils with high compaction potential. (4-28)
  • Revegetation Potential-103.6 miles (52%) of line are soils with revegetation concern. (4-28)
  • Shallow Bedrock- of 36.8 miles of Lancaster Co- 18.6 are expected to NOT need blasting, but 17.4 are expected to need blasting because made up of hard bedrock. (4-29).
  • Staging areas-no significant impacts on soils expected- although rough grading and vegetation clearing will be done, it would be restored after construction in accordance with landowner lease agreements. (4-30) (and what if the landowners didn't know to detail such restoration in their contracts- or only did it verbally- who will hold the industry accountable?)
  • 115 temporary access roads, and 40 permanent access roads totalling 235.5 acres of land- (4-31)
  • ... maintaining strict minimal standards of the protection of soil resources and environmentally sensitive areas. (4-31)
  • Transco would use erosion control devices and construction practices to minimize erosion during and after construction. (4-31)
  • The loos of topsoil from erosion or the mixing of topsoil with the subsoil during construction could result in a loss of soil fertility and impaired vegetation.
  • Transco would (not will- which begs the question.. would if what?): segregate up to 12 inches of topsoil to maintain surface horizons with highter organic matter content, backfill rock fragments to only the top of the natural bedrock, test topsoil and subsoil for compaction at regular intervals (what constitutes regular intervals?), where drain tiles would be crossed, maintain flow to the drainage system during construction. (4-32).
  • few studies have addressed the effects of heat from pipelines on crop growth (4-33).
  • Trancso proposes to bury the pipeline with a minimum depth of cover of 4 ft in active ag area- Transco would compensate farmland owners and/or tenants of r crop loss and would conduct crop yield monitoring at the request of the landowner until the reclamation process has resulted in crop growth. (does this mean even if it isn't in the agreement they industry is willing to do this?) (4-33)
  • To the extent practicable- Transco would avoid Construction during periods of heavy rainfall, snowmelt, or unusual soil saturation. (What does this mean- rain is often unpredictable, and once construction is begun, you can't back it up.. so this seems to be a vacuous statement, with no protection for the land whatsoever.) (4-33)
  • revegetation by Transo- using seed mix composed of grasses, herbaceous plants, and legumes, or as specified by landowner. (need this specification by landowner be in the written contract?) (4-33)
  • Transco would monitor all disturbed areas for a minimum of 2 growing seasons- areas that have not revegetated successfully would be corrected to ensure the right of way conditions are similar to surrounding undisturbed areas (note, not to that of the condition before the pipeline installation). (4-34)
  • Soil contamination- either by hazardous material or fuel spills- typically are minor because of the low frequency and volumes of spills and leaks. (4-34).
