Traffic

1-13     Please provide details regarding the expected noise to be generated by traffic (truck and other vehicles) during construction and routine operations.

1-15     Please provide any study or other information in Invenergy’s possession regarding traffic issues that may arise during and after construction, including identifying the access road that will be used during and after construction, the location and details of the proposed road(s), and the impact of traffic on the neighborhood during and after construction.

4-3       How many trucks will be traveling Town roads during construction of this project?

5-5       Please provide a complete traffic study, including all traffic impacts, potential truck routes, and restrictions.

6-1      With the increase in traffic through densely settled areas, what is the increased risk statistically of accidents and risk of a hazmat spill? 

6-2      What is the emergency response plan should a large tanker truck or other tractor trailer be involved in an accident and lose their cargo? 

6-3      Has any consideration been given to improving Jackson School House Road or Buck Hill Road and to use one as a bypass of the villages of Chepachet and Pascoag?

6-4      If Route 44 and 100 are the primary trucking routes for construction, what are the contingencies for compensation should homes be damaged by the impact of the truck traffic? 

6-5 Is there a plan to repair roads damaged by traffic from construction?

6-6 Where is the proposed laydown area?  Has this location and its potential impact been included in the traffic studies?

13-1     Page 3:  By what criteria were only the driveway and two unsignalized intersections identified for the study?  Were no other intersections along the Route 100/Route 44 corridor affected by a 400 vph site traffic increase?

13-2     Page 5:  Is Main Street really 62 feet wide?

13-3     Page 7:  The statement that the weekday afternoon peak hour of adjacent streets occurred between 5 p.m. and 6 p.m. (3rd paragraph) does not appear to be supported in the appendices.  Please explain.

13-4     Page 8:  How was the period (3:15 – 4:15) in the heading of the far right column determined?  See 13-3 above.

13-5     Page 11:  Route 100 / Route 44 roundabout:  While no detours are anticipated, couldn’t other traffic control strategies such as temporary lane blockage or temporary alternating traffic flow introduce traffic disruption and delays?

13-6     Page 25:  3rd paragraph – Please clarify the PM Peak Hour (See 13-4 above).

13-7     Page 28:  2021 Construction Build, Pascoag Main / South Main – Please define the “short duration” of the degraded turning movement operation.

13-8     Page 28:  2021 Construction Build, Pascoag Main / South Main – How much of a decline in level of service would have been experienced had it NOT been conservative?

13-9     Page 29:  2021 Construction Build, Pascoag Main / Church – Please define the “short duration” of the degraded turning movement operation.

13-10   Page 29:  2021 Construction Build, Pascoag Main / Church - How much of a decline in level of service would have been experienced had it NOT been conservative?

13-11   Page 30:  Table 6 – Is there sufficient Intersection sight distance in both directions?  The table and text are unclear on this.

13-12   Page 30:  The last paragraph refers to adequate sight distance for heavy vehicle access, but the bottom of Page 29 states the design vehicle is a single unit truck.  Are these the same vehicles?

13-13   The Traffic Impact Study notes Invenergy’s commitment to an appropriate level of restoration for roadway sections degraded by the construction-related traffic.  Is Invenergy prepared to sign an agreement evidencing this commitment?  If so, will Invenergy prepare such a proposed agreement and forward it to the Town’s attorneys?

15-3     Do you have any specific traffic information available for accidents involving trucks, as opposed to automobiles, and what is your projection regarding the probability of increased truck accidents with the proposed facility?

22-2 Under the water plan, is it correct that Water Filter Bed media turnover introduces 2 new truck trailers on the roadway per month? That equals 4 trips to and from the site per month. Please explain.

22-5 Under the water plan, is it correct that water replenish rate after an oil fired operation event is 11 trucks per day, or 22 trips to and from the site? Is this a guarantee? Please explain.

22-6 Under the water plan, is it correct that oil replenish rate after an oil fired operation event is 7 trucks per day, or 14 trips to and from the site? Is this a guarantee? Please explain.

22-7 Under the water plan, is it correct that you have assumed an oil run event duration for 3 days? What if there is an extended run of this power plant for more than 3 days while running on oil? Do you agree that this would increase the number of truck trips to and from the site during a week's time or longer? Please explain.

22-8 Under the water plan, is it correct that the worst case scenario you present is that oil tank depletion (2 MG) will equal 19 trucks per day to replenish, or 38 trips to and from the site? Is this a guarantee? Please explain.

22-9 Under the water plan, is it correct that the average truck rate after an oil operation event will be 22 trucks per day new traffic or 44 trips to and from the site? Could this be exceeded? Please explain.

22-10 Under the water plan, is it correct that the traffic engineer assumes each truck carries 8,000 gallons per truck but the water host agreement indicates a truck is 7,200 gallons per truck? Do you agree that a recalculation of the traffic engineer's figures are needed, which will increase the truck figures identified above in items 1 through 9? Please explain and provide the recalculation.

22-11 Under the water plan, do you agree that Table 2 of McMahon's traffic report is now underestimated due to estimated tanker truck size, and assumes only a 3-day operation event running on oil, so it technically is not the "worst case scenario"? Please explain.

22-24 Provide the estimated monthly number of mobile demineralization trailers that will be needed per calendar year between 2019 and 2038 to operate the CREC and the total cost.

22-34 The plan outlines a lengthy refill strategy of up to 1 month where approximately 9 additional trucks per day (72,000 gpd) will be used.

22-39 Please verify the water truck planned capacity, which has been reported as both 7,200 gallons and 8,000 gallons.

22-40 The Trip Generation in the original report (May 2016) does not specifically reference an oil-fired event. Please explain in detail the assertion that the generated traffic from such an event has been reduced.

22-41 Is there a plan for monitoring and/or enforcing the voluntary extension of the oil-firing replenishment duration? Are the specifics of this duration extension documented somewhere? Wouldn't this be inefficient and costly for the operators? Please explain.

22-42 What truck percentages were used in the previous signalized intersection analyses and in the updated analysis? Please explain.

22-43 Please provide the Synchro © (computer analysis) files for the signalized intersection analyses for both the current projections and the original projections.

22-45 Please provide the total estimated truck emissions that will be generated on an annual basis, by type and amount, for all of the trucks coming and going from the facility:

22-49 CREC's traffic Consultant McMahon Transportation. Engineers and Planners has analyzed the intersection of Pascoag Main and South Main Street Intersection's Level of Service (LOS) and reported that it degrades to "E" during construction for "short periods." Please have the consultant re-evaluate this intersection for the water refill truck traffic both during construction and post-construction and during water and oil refilling operations and provide a copy.

22-50 Please have the CREC Traffic Consultant review and analyze tanker truck movements through the Pascoag Main/South Main Street and the Route 100 (Church Street) and High Street intersection because these movements require water tanker trucks to cross the centerline in order to make the turns and provide a copy. Please explain whether this movement will likely affect the LOS.

22-51 Please have the CREC Traffic Consultant review and report on the truck turning radii versus the road geometry.

22-52 Please have the CREC Traffic Consultant review and report on the corner geometry versus turn radii at the Church Street corner adjacent to the Community Baptist Church and School.

22-53 Please have the CREC Traffic Consultant review and report on the sight distances at the Route 100 corner at Serio's Pizzeria.

22-55 What is the increased projection of accidents and spills which could occur by the increase in truck traffic at the four intersections/corners described above?
