Project Replacement of 2 Septic Systems – Middle 3 Bedroom House on Reserve Ranger District and Middle 2 Bedroom House on Reserve Ranger District

General Information

1.0 Scope of Work

The contractor shall decommission and legally dispose of the existing septic systems for each respective building and replace each with a septic tank and a leach field. The contractor shall size the septic system (tank and leach field sizes) according to NMED standards (see appendix A and appendix B for layouts of the buildings as reference). As such, all demolition and construction must comply with New Mexico Environment Department (NMED) standards. Contractor is responsible for blue stake permitting, tools, labor, equipment, supplies, and any additional permitting as required.

2.0 Background

The current septic systems are outdated and non-functional. This contract aims to ensure the new systems meet NMED standards and are consistently and foreseeably functional.

Location: Reserve Ranger Station 5 Smokey Bear Circle, P.O. Box 170, Reserve, New Mexico, 87830 the two buildings are indicated in the below photo with placemarks.

Contractor Requirements/ Construction Specifications

3.0 Technical Requirements / Tasks

1. Mobilization/Demobilization

Tasks:

•Pre-Mobilization Planning:

•Develop and submit a mobilization plan for approval.

•Conduct a site survey to identify access routes, staging areas, and environmental considerations.

•Obtain all required permits for equipment transport and staging.

•Mobilization:

•Deliver necessary equipment to the site, including excavators, trucks, tools, supplies, equipment, and safety gear.

•Set up staging areas for equipment, materials, and temporary facilities (e.g., trailers, portable restrooms if necessary).

•Install site signage for safety and project identification as well as ensure a clean and orderly work site. Contractor is responsible for site security. Should the contractor encounter any findings of archeological significance (bones) at any point during the excavation process, work must cease, and this must be reported immediately to the COR for inspection. Work may only resume once archeological clearance is given by the Forest Service.

•Erect erosion and sediment control measures (e.g., silt fences, wattles) per NMED and EPA guidelines.

Demobilization:

•Remove all temporary facilities and equipment.

•Clean and restore staging areas to pre-construction condition.

•Dispose of waste materials (construction debris, unused supplies) in accordance with NMED standards as well as all applicable local and federal regulations.

•Perform a final site inspection with stakeholders to ensure restoration standards are met.

•Submit demobilization report to the client and relevant authorities.

2. Decommissioning and Disposal of Existing Septic Systems

Tasks:

•Site Assessment:

•Locate and map the two existing septic tanks, distribution boxes, and leach fields.

•Decommissioning/Disposal Process:

•Pump out existing septic tanks and dispose of contents at an approved waste treatment facility.

•Decommission and legally dispose of all materials from each system according to NMED standards.

•Backfill excavated areas with clean fill material.

•Technical Requirements:

•Comply with NMED regulations for septic tank decommissioning.

•Follow OSHA excavation and trenching safety standards.

•Utilize spill containment measures for any hazardous materials encountered.

3. Installation of New Septic Tanks (Per NMED Requirements)

Tasks for each system (2 systems in total):

•Design and Permitting:

•Submit detailed designs to NMED for approval, including tank sizing, location, and connections as required.

•Obtain installation permits as required from NMED and local jurisdictions.

•Site Preparation:

•Clear and grade the area for tank installation, ensuring proper slope for gravity flow.

•Excavate for the septic tank to specified dimensions, accounting for backfill and compaction requirements.

•Tank Installation:

•Install septic tank according to manufacturer specifications and NMED standards.

•Level and secure the tank to prevent shifting or settling.

•Install inlet and outlet connections, including watertight seals to prevent leaks, and cleanout sweeps.

•Backfill around the tank with appropriate material, compacting in layers to prevent settling.

•Technical Requirements:

•Use NMED-approved tanks made of durable materials (e.g., concrete, fiberglass, or plastic).

•Verify tank location meets setback requirements (e.g., distance from structures, wells, and watercourses).

•Ensure all connections meet code requirements, and the systems are free from leaks.

•Install risers and access ports for future maintenance.

4. Installation of New Leach Fields (Per NMED Requirements)

Tasks for each system (2 systems in total):

•Design and Permitting:

•Design leach fields to meet capacity needs and NMED standards.

•Submit plans for leach field design, including trench dimensions and layout, to COR.

•Obtain installation permits.

•Site Preparation:

•Clear vegetation and debris from the leach field area.

•Excavate trenches to the specified depth, width, and grade, ensuring proper spacing between trenches.

•System Installation:

•Lay leach systems in trenches, ensuring proper slope for even effluent distribution.

•Surround pipes with approved backfill material to specified depth.

•Cover aggregate with a geotextile fabric if required to prevent soil infiltration.

•Backfill trenches with clean topsoil, grading the area for drainage.

•Technical Requirements:

•Ensure leach field dimensions meet percolation rates and soil capacity per NMED standards.

•Maintain setback distances from property boundaries, water sources, and structures.

•Incorporate inspection ports for future monitoring of the system as required.
