Scope of work:

The contractor shall furnish all labor, supervision, equipment, tools, parts, supplies and materials, as necessary, to perform the services as described herein:

Cost for Line Item #1 (include total cost for items A-K) These are known factors. Vendors must invoice for actual cost incurred as described herein.

A) Construct an Alternative onsite sewage system that meets the location and construction specifications of the Virginia Sewage Handling and Disposal Regulations (12VAC5-610-10 et seq., the Regulations).

B) Construct the above Alternative onsite sewage disposal system in compliance with the Warren County Health Department Construction Permit 187-23-0420 at 29 Apache Court, Front Royal, VA 22630 in the location shown on the permit.

The permit contains additional conditions, notes, and information needed to construct the onsite sewage system. On sheet 5 of 11, drawing page notation states:

· Contractor to verify tank working order and condition.

· Contractor to confirm existing pump type (Zoeller 140) and working condition/order

· Contractor to confirm existing control panel working condition/order.

All bids received should include what is existing and detailed in the plans as they are written. Once the contract with VDH SWAP has been negotiated and executed, if the contractor determines that the existing tank, pump, or control panel need replacing, these changes shall be handled by way of submission of a change order.

C) Septic Pump-out Requirements: All bids shall include the cost to pumpout the contents of the existing septic tank by a properly licensed sewage hauler. Bids should provide a cost-breakdown per additional pumpout. If multiple pumpouts are needed preauthorization will need to occur to allow for a change order for additional, justifiable pumpouts.

· If needed, to eliminate raw sewage currently backing up into the home, the contractor shall arrange for an initial emergency pump out of the onsite septic tank by a properly licensed sewage hauler within 72 hours of signing the Notice to Proceed.

· To prevent sewage from backing into the home or erupting on property surface prior to the completion of the septic work, additional pumpouts of the contents of the existing septic tank by a properly licensed sewage hauler may be required on an as-needed basis.

· If the permit requires work within or under the existing drainfield (as indicated in the Permit) additional monitoring and pumping of the existing septic tank may be required in order to allow for the drying out of the drainfield. In these cases, for one week prior to the installation or repair of the onsite sewage system the effluent level of the septic tank must be monitored so that it does not discharge into the pump chamber or dispersal field. The contents of the existing septic tank shall be pumped by a properly licensed sewage hauler to prevent sewage from entering the drainfield for one week prior to installation.

D) Removal of Existing Peat Treatment unit:

· Existing Peat Treatment Unit to be removed according to health department policy, GMP-143-A, dated 14May2024. https://www.vdh.virginia.gov/content/uploads/sites/20/2016/05/GMP-143-A_5-14-14.pdf

· Dewatered and limed peat is considered solid waste and may be disposed of in approved landfills.

1) Contractor should confirm acceptance of the spent media with the landfill before delivering it.

2) Follow manufacturers guidelines regarding acceptable peat removal techniques.

3) The spent media shall be mixed with hydrated lime at a rate of one pound of lime per 0.9-1.0 cubic feet of media (approximately one, 50-pound bag of lime per Puraflo module. See GMP for additional information). The spent media and the lime are to be thoroughly combined to ensure adequate contact and mixing of the peat and lime.

4) The spent media should not exhibit any free liquid when placed into the landfill.

E) Tree Removal and Site Clearing: A pre-bid site visit is recommended to determine what, if any, tree removal or site clearing may need to occur. Per the above referenced Permit, remove any trees and wood debris as described in the permit and haul away wood and debris unless notified otherwise. Costs of tree removal and site clearing should be included in initial bids. Any additional site clearing, or tree removal required during installation must be submitted in writing to and approved by VDH in writing including an additional cost estimate. Any personal property items that will prohibit the contractor from accessing the site or installation of the new system is the responsibility of the homeowner to remove and should not be included in the bid.

This includes obtaining or assuring that the owner obtains all permits and inspections necessary by the local building authority in compliance with the Virginia Uniform Statewide Building Code.

G) Operation and Maintenance (O&M) Requirements: As the SWAP will fund two years of regulatory O&M for the Alternative Onsite Sewage System (AOSS) installed on this property, please provide or subcontract for two years of O&M unless the cost is included in the purchase price of the treatment unit. Arrange and schedule an initial site visit with the contracted O&M provider prior to submission of the final invoice, preferably at the system startup. Provide documentation from the service provider that the site visit occurred. The O&M requirements can be found in the Regulations for Alternative Onsite Sewage Systems 12 VAC 5-613. The O&M agreement shall include the maintenance visits and any samples as required by the AOSS regulations. This funding is provided to assist the homeowner at meeting their first two years of O&M requirements per the Owner's Operation and Maintenance Manual and the Regulations for Alternative Onsite Sewage Systems (12VAC5-613-100 et seq.). The first two years of O&M listed in the agreement should be at no cost to the homeowner. Contractor shall provide a copy of the O&M agreement to the homeowner and provide a copy to VDH.

H) Abandon any unused component of the former onsite sewage system as specified by the Warren County Health Department Construction Permit 187-23-0420. Upon completion of the onsite sewage system repair, the existing septic tank shall be pumped by a properly licensed sewage hauler, the tank crushed in place, lime placed over the crushed tank, and the tank hole filled with clean backfill material and restoring the area to its original condition. Abandonment may also include removing unused sewer line and conveyance lines and crushing and filling the distribution box. Please see section (D) Removal of Existing Peat Treatment unit and the Warren County Health Department Construction Permit 187-23-042for more information regarding the requirements for abandonment of former septic system components.

· The permit requires removal of the existing peat system. It may be necessary to install, have approved and placed into operation, the proposed repair, prior to removal of the existing peat system, allowing sufficient time for the peat to adequately drain prior to removal to the landfill.

I) Follow all regulations and permitting pertaining to erosion and sediment control including stabilizing, seeding, and grading the site after construction to return to the original state.
