Answer: WWM has no objection to this change. Intent is to provide manufacturer revisions to software/firmware.

52. Drawing WW-G-01 Sequence of Operations Paragraph 2: Influent wastewater flow… through a comminutor for solids reduction. Please consider eliminating the comminutor from the project. Comminutors are not recommended and typically not used for MBR systems.

Comminutors can "tear up" certain types of materials (e.g fibers) in such a way as to allow them to pass through the fine screens. When in the reactors, these materials can then re-agglomerate and create problems. The fine screens are more effective, the membranes are best protected, and the overall plant health and reliability is best served, by eliminating the comminutors.

Answer: The concern is noted.

53. Drawing WW-G-01 Sequence of Operations Paragraph 2: …In the event that incoming wastewater volume exceeds 90,000 GPD, influent can be directed to the second process train for solids removal and temporary storage of up to 75,000 gallons, then returned to the primary equalization tank for treatment with the incoming flow rate has returned to normal. Please confirm if the system is intended to be operated as only a single treatment train. This operation would not be recommended unless start-up lows are expected to be very low. It would be beneficial to issue via addendum a summary of expected start-up/minimum flows.

Answer: The system is intended to be operated initially as a single train system, with the second train available as a back up, or to be used on a semi-annual rotating basis. Based on historical records at the existing WWTP, the expected average daily flow at start up is approximately 40,000 gallons per day and may fluctuate daily between 20,000 gallons per day and 90,000 gallons per day.

54. Drawing WW-M-01 Sequence of Operations Overflow shown within headworks channel.

This overflow should be eliminated. Influent wastewater that has not passed through a fine screen should never be allowed to enter the reactors. Reliability/redundancy in screen design should be sufficiently robust so as to eliminate the need for any overflow/bypass.

Answer: The concern is noted.

Report of Subsurface Exploration and

Geotechnical Evaluation Waste Water Treatment Plant Upgrade

Mount Weather EOC Mount Weather, Virginia

April 25, 2014

Mr. Rich Brannan Waste Water Management, Inc.

2820 Dorr Avenue, Suite 200 Fairfax, Virginia 22031

ECS Project No. 21:10594

Reference: Report of Subsurface Exploration and Geotechnical Evaluation Waste Water Treatment Plant Upgrade Mount Weather EOC Mount Weather, Virginia

Dear Mr. Brannan:

ECS Mid-Atlantic, LLC (ECS) is pleased to submit this Report of Subsurface Exploration and Geotechnical Evaluation for the above referenced project. Our services have been provided in general accordance with ECS Proposal No. 21:19315, dated January 27, 2014. This report contains the results of the field exploration, laboratory soil testing, and presents geotechnical recommendations for the project.

SCOPE OF SERVICES

The conclusions and recommendations presented in this report are based in part upon the results of the field exploration. The field exploration consisted of a site visit by an experienced geologist and eight (8) soil and rock borings advanced to depths ranging from approximately 2.9 to 32 feet below the existing surface grades. Laboratory testing was performed on representative soil samples obtained during the field exploration to aid in the evaluation of the field data.

The recommendations presented herein are based on the interpretation of the subsurface data provided by the soil borings. The borings indicate subsurface conditions at specific locations at the time of the exploration. The borings, laboratory testing, and this report preparation complete our Scope of Services. If variations appear evident during the course of construction, ECS should be contacted so that the conditions may be addressed.

ECS Project No. 21:10594 April 25, 2014

PROJECT DESCRIPTION

The site is located at the Mount Weather EOC facility in Mount Weather, Virginia. We understand that an upgrade is planned for the existing Waste Water Treatment Plant. The project includes a new 180,000 GPD plant, a realigned entrance roadway, and associated infrastructure. Current plans call for regrading portions of the sloping terrain surrounding the treatment plant site and along the entrance roadway.

The planned WWTP building will be a two-story structure having plan dimensions of approximately 45 feet by 102 feet. The current design finish floor elevations of the upper and lower levels are 1418.0 and 1407.5, respectively. These levels will contain the headworks, an electrical room, a mechanical room, a blower room, a sludge tank room, and a sludge dewatering area. The chemical room is located along the northern side of the structure has a design finish floor elevation of 1422.50. The sludge tanks, located at a lower level within the northern half of the structure, have a bottom elevation of 1397.50. Considering the design floor elevations and the sloping terrain, portions of the northern, eastern, and western side walls of the building will be constructed below grade.

A new site lift station will be constructed just south of the new treatment plant. This facility will have a precast concrete box and an adjacent 7-feet diameter well. The base of the concrete box will be 7 feet in the ground. A base elevation of 1387.5 has been established for the well.

Foundation loading information has been provided by Mabry Engineering Associates, the project structural engineer. The maximum main building wall loads will be 12 kips per linear foot (klf). Wall loads for the Chemical Room will be 3 klf. A mat foundation will provide support for the sludge tanks and will transmit a maximum in-service loading of 1.5 kips per square foot (ksf).

SUBSURFACE EXPLORATION PROGRAM

FIELD EXPLORATION

A subsurface exploration consisting of eight (8) soil and rock borings was performed at the site to characterize the general subsurface conditions. B-1, B-3, and B-4 were drilled within the general alignment of the new access roadway. The remaining borings were drilled within or just outside the footprint of the planned new waste water treatment plant building. The locations of the borings are depicted on the Boring Location Plan in the Appendix.

The number and locations of the borings were established by Waste Water Management, Inc.

(WWM). The borings were located and staked at the site by representatives of WWM and ECS during a site meeting prior to drilling. The ground surface elevations at the boring locations were also provided by WWM.

During the field exploration, a couple of the borings were offset slightly from their original staked locations due to buried utility conflicts and drill rig set up constraints. B-2 was moved a few feet into the roadway and away from the edge of the slope as well as marked utility lines. B-3 was shifted slightly east since the boring marker flag could not be located as it had been snow plowed. Finally, B-4 was offset slightly to accommodate setting up the drill rig off the hillside.

Representative samples of overburden soils and weathered bedrock were obtained by means of the split-barrel sampling…
