	The majority of transportation projects in Missouri are classified as categorical exclusions (CEs) and are completed as a programmatic CE (PCE) or a CE2. Approximately 96% of LPA projects have been classified as programmatic CEs, with the remainder classified as CE2s and very rarely as an EA or EIS (see [[127.14 National Environmental Policy Act (NEPA) Classification and Documents#127.14.5 NEPA Glossary\|EPG 127.14.5 NEPA Glossary]]).		The majority of transportation projects in Missouri are classified as categorical exclusions (CEs) and are completed as a programmatic CE (PCE) or a CE2. Approximately 96% of LPA projects have been classified as programmatic CEs, with the remainder classified as CE2s and very rarely as an EA or EIS (see [[127.14 National Environmental Policy Act (NEPA) Classification and Documents#127.14.5 NEPA Glossary\|EPG 127.14.5 NEPA Glossary]]).

	An agreement with FHWA allows MoDOT to automatically classify specific types of projects that require no more than 5 acres of new right of way and/or easements combined, or exceeds one of the thresholds, as PCEs. PCEs do not require FHWA review. MoDOT and FHWA executed the newest [~~[media~~:~~2023_PCE_Agreement~~.pdf\|programmatic agreement]~~] on September 22, 2021~~. The thresholds that cannot be exceeded are contained within the agreement. If a project exceeds one of the thresholds, a CE2 must be approved by FHWA.		An agreement with FHWA allows MoDOT to automatically classify specific types of projects that require no more than 5 acres of new right of way and/or easements combined, or exceeds one of the thresholds, as PCEs. PCEs do not require FHWA review. MoDOT and FHWA executed the newest [https://epg.modot.org/forms/general_files/DE/ENV/PCE_agreement.pdf programmatic agreement] in 2026. The thresholds that cannot be exceeded are contained within the agreement. If a project exceeds one of the thresholds, a CE2 must be approved by FHWA.

	For projects that require over 5 acres of new right of way and/or easements combined, or exceeds one of the thresholds, MoDOT will advise the LPA to complete a [https://epg.modot.org/forms/general_files/DE/ENV/CE2_Template.docx CE2 Form] describing the project, the impacts expected from the project, and mitigation to compensate for the project’s impacts. The CE2 will require information such as the federal project number, route, county, project termini and length, project description, current and future average daily traffic (ADT), right of way and easement needs, displacements/relocations, a location map, and any other associated attachments. [[media:136.6.5.pdf\|Fig. 136.6.5, Instructions for Preparing a CE2 Form]], guides the LPA through the process. For FHWA to concur that the project is a CE2 instead of an EA or EIS, the CE2 document must clearly demonstrate that the project will not have significant impacts and therefore, is categorically excluded from the requirement to prepare an EIS or EA. MoDOT will notify the LPA of the CE2 approval, request for more information, or FHWA’s decision that an EA or EIS needs to be prepared.

	A number of laws and regulations deal with hazardous waste and both underground and aboveground storage tanks. Properties containing hazardous and non-hazardous solid wastes are frequently encountered in new right-of-way acquisitions. Some properties with extensive contamination and legal liabilities may warrant avoidance. For most sites, however, early identification and planning will allow selection of feasible alternatives with incidental costs. In addressing hazardous and solid wastes, the goals are to avoid unacceptable cleanup cost and legal liability and comply with federal and state laws and regulations regarding cleanup.

	Borrow/spoil sites, staging areas, haul roads, and/or burn pits may be located outside the project footprint and therefore were not previously addressed by the NEPA document and other environmental approvals for the project. The LPA is responsible for ensuring that the contractor obtains all necessary environmental clearances for borrow sites and other land disturbance areas—including off-site locations used to deposit excess material or for haul roads. To eliminate possible delays, the LPA should specify in the engineering services contract that a proposed borrow site be investigated. The LPA will provide clearance documentation to the MoDOT district contact.

	Stream and/or wetland impacts exceeding 0.5 acre or channelization beyond the minimum necessary to construct or protect the linear transportation project may require an individual permit. If the COE issues an individual Section 404 permit for project activities, the LPA must obtain an individual Section 401 Water Quality Certification from the Department of Natural Resources (DNR). For a nationwide permit (NWP), the LPA is obligated to follow the conditions specific to the appropriate NWP within DNR’s conditional 401 certifications. Most NWPs will not require an individual request for DNR’s Section 401 Water Quality Certification, because the agency has granted conditional certification for the majority of commonly used NWPs. The LPA must include the appropriate 401 certification conditions for their respective NWP(s) in the construction contract (see Item no. 3, below, for link to conditions).

	Cultural resource surveys typically are limited to the area of potential effects (APE). For archaeology, this is the maximum footprint of the project consisting of proposed and existing right of way, and permanent and temporary easements and any off-site areas, if known (e.g., borrow, staging, wasting, etc.). For architectural resources, the APE may include the limits of the project plus a buffer around the project area so indirect effects of the project are considered (usually 50 ft in urban settings and 100 ft in rural settings).

For architectural resources, the APE may include the limits of the project plus a buffer around the project area so indirect effects of the project are considered (usually 50 ft in urban settings and 100 ft in rural settings).

	:1. An architectural survey consists of photographing buildings within the architectural APE and providing descriptions and historical information about those buildings constructed 45 years ago or older. In addition to buildings, features associated with a property such as gateposts, hitching posts, outbuildings, signage, etc. should be included in the photographic coverage. Clear photographs, which show the resource clearly, should be included in the survey report. Photographs taken out of car windows or where the resource is hidden behind vegetation are not acceptable. All surveys conducted on behalf of the Missouri Department of Transportation (MoDOT) must follow MoDOT’s Built Environment Survey Methods. These methods will help establish the Area of Potential Effects (APE), identify resources within the APE, determine which resources should be surveyed if not clearly inside the APE, and what to do if a bridge is located inside the APE. The consultant working on behalf of MoDOT must contact the MoDOT HP Office to obtain a copy of MoDOT’s Built Environment Resource Methods before fieldwork is conducted. The consultant must send a copy of their APE to MoDOT’s Historic Preservation Office before they conduct fieldwork so a Historic Preservation Specialist can review it. A meeting is recommended to be schedule before any fieldwork is conducted so a Historic Preservation Specialist can answer any questions the consultant may have before fieldwork is conducted. A meeting can also be scheduled after fieldwork to discuss the results.		:1.

	:2. A Phase I archaeological survey is an intensive, systematic, investigation of the APE of the proposed project to identify any archaeological site that may be affected by the proposed project. If there is good surface visibility (e.g., a plowed field), archaeological sites may be identified by a pedestrian survey, which consists of archaeologists walking the area to examine what is exposed on the surface. If there is poor surface visibility (e.g., a pasture) the archaeologists use shovel or auger tests to look for artifacts. Shovel tests are small hand-dug holes about 12 inches wide and up to 24 inches deep, while auger tests are 8-inch diameter holes up to 6 feet deep. In most survey areas, shovel tests or auger tests will be excavated at 50-foot intervals. The excavated soil is examined for artifacts and other evidence of prehistoric or historic archaeological sites.		:2.

	:Phase II archaeological site testing will be needed if any potential National Register eligible sites are encountered in the APE that could be impacted by the proposed project. The Phase II is a limited archaeological excavation of a site to determine its significance and whether it meets National Register eligibility standards. The standard method for testing an archaeological site is the hand-excavation of test units. Test Units are usually 3 ft. x 3 ft. or 3 ft. x 6 ft. in size and are dug usually to a depth of 3 to 4 feet. These test units are excavated to search for intact artifact deposits and/or features (e.g., hearths, storage pits, foundations, wells, cisterns, etc.) that would provide information about the people whose activities had created the site. The archaeological consultant will need to consult with SHPO and MoDOT on the proposed Phase II testing strategy before it is implemented.
