1-17     Please identify in detail the company’s plans regarding water quality, water use, storm water run off, and waste water.

4-21     What is the method of replenishment of the aquifer?

4-23     If the used water is clean and can be introduced back into the stream and local ponds, could Invenergy build a dam to provide adequate time for the water to percolate through to Pascoag aquifer and complete the circle allowing a flushing action to assist in the removal of the existing contaminates?  If not, why not?

5-2       Please identify the exact water pipe line route and plans for construction.

5-3       Please identify and describe the proposed water treatment system with activated carbon, including a description of the safety protocols that will be present for treatment of the contaminated water.  Please include an evaluation of carbon breakthrough and provide a copy of the proposed treatment system operations and maintenance manual.

5-4       Have you made an evaluation of the presence of contaminants in the cooling water relative to evaporation, the potential increased concentrations, and to the waste stream going to the Burrillville water treatment facility?

5-12     Can any emissions or pollution from the contamination build up in the activated carbon filtration system pollute the local air or water?  Please explain.

5-13     Where does the spent activated carbon laden with MTBE go once it is used?

5-16     What is the output production rating of the defunct Pascoag Utility District water wells?

5-17     Can these water wells meet the proposed type of long term water supply demand without significant constraints on the ground water resources adjacent to the wells?

5-18     If Pascoag Utility District wells do not meet the demand for the power facility, where will the water come from?

5-19     Exactly where will the facility obtain potable water for human consumption?

6-9       Explain in detail the level and frequency of testing for adjacent water sources (to well 3A) for MTBE contaminates to ensure the extraction of water from well 3A does not cause the pollution to spread to other water sources.

6-10     Explain in detail your remediation plan should the contamination from well 3A spread to surrounding water sources/areas.

6-11     How does Invenergy intend to overcome the court order shutting down Pascoag well 3 and 3A?

8-1       GAC Treatment following Extraction at the Pascoag Well – The proposed granular activated carbon (GAC) treatment system needs to be evaluated.  In Table 6.2-2 of the October 2015 application, the proposed MTBE concentration going to the proposed plant is 55 µg/L, and following use at the plant as cooling water, the compositional projection of MTBE going to the Burrillville WWTP is 200 µg/L.  Please provide a process and instrumentation diagram for the proposed GAC treatment system.

10-1     Should breakthrough occur during use of the Town’s granular activated carbon treatment system, and the well water supplied to the facility contains MTBE at levels currently present in the groundwater, what fraction of the MTBE present in the untreated well water would be expected to volatize and be released as an air emission and what fraction of the MTBE would be expected to discharged to the Burrillville Sewer?

10-2     Regarding the “3.865 Kilometer, significant impact zone” referenced in the EFSB application, please explain in detail what it means and provide all information on any potential impacts to anyone residing within the radius.

11-1     Does Invenergy intend to perform any pump tests and water sampling and testing at the PUD Well #3A?  If so, please provide details on the pump test, including duration and flow rate and information on water sampling testing.

11-2     Does Invenergy intend to perform any vapor intrusion assessments on the properties in the vicinity of PUD Well #3A?  If so, please provide details on the testing.

16-1     Please provide details of the potential exposure to natural gas shortages that may require the proposed plant to utilize its onsite water supply and potentially have to use back up methods, such as trucking water.

16-2     Please provide data showing what has actually happened with regard to natural gas shortages requiring power plants in the ISO-NE local zone to switch from natural gas to diesel fuel and provide details about each incident available within the last five years.

16-3     Please explain how the potential exposure to natural gas shortages, as described above, would change if Invenergy opted to obtain fixed gas supply contracts for both of its turbines rather than for only one.

16-4     Please provide all information demonstrating whether there is a history or pattern of extended natural gas shortages for power plants in the ISO-NE local zone, how long those shortages typically last, the likelihood that fuel oil will be needed to run the plant, and how many instances where such shortage could last longer than 3.65 days.

16-5     Please identify in detail all water supplies for the proposed facility that you currently have under consideration and the development status of each one.
