2.1 Data Collection and Regulatory Review: • Identify and review all applicable laws and regulations of the Navajo Nation, which is the primary regulatory authority. The review must also include any applicable United States Environmental Protection Agency (U.S. EPA) federal regulations and New Mexico state regulations that may apply to the project or its potential off-reservation impacts. • Collect and review all available technical data, including geologic maps, aquifer studies, well logs from the Navajo Nation Water Code Administration and the New Mexico Office of the State Engineer (OSE), and existing water quality reports. 2.2 Site Investigation and Characterization: • Conduct a thorough site visit to assess existing infrastructure, topography, and potential locations for new wells or connections, in coordination with the local Chapter House and any grazing permit holders. • Evaluate potential hydrogeological or environmental constraints that could impact the project. 2.3 Water Demand Analysis: • Develop a detailed water demand model to estimate the average daily, maximum daily, and peak instantaneous water requirements for the fully operational travel center and hotel, consistent with NNEPA and applicable federal standards. 2.4 Water Supply Options Analysis: • Connection to Public System: Assess the feasibility, capacity, and cost of connecting to an existing public water system, including any requirements from the Navajo Tribal Utility Authority (NTUA) or other local providers. • On-Site Groundwater Development: Evaluate the potential for developing onsite water wells. This shall include an assessment of probable drilling depths, water yield, and long-term sustainability, adhering to the Navajo Nation Water Code and any relevant U.S. EPA requirements for sole source aquifers. 2.5 Water Quality Analysis: • Propose a plan for collecting water samples for certified laboratory analysis, evaluating the results against the standards established by the NNEPA Public Water System Supervision Program. These standards must meet or exceed the National Primary Drinking Water Regulations set by the U.S. EPA. • Identify potential water quality concerns and recommend appropriate treatment solutions that are compliant with all applicable regulations.
