<strong>Project</strong> Purpose: The <strong>New</strong> <strong>Mexico</strong> <strong>Department</strong> <strong>of</strong> Transportation (<strong>NM</strong>DOT), in cooperation with<br />

the Federal Highway Administration (FHWA), proposes to construct the following three curves in<br />

Lincoln County, <strong>New</strong> <strong>Mexico</strong>: Texas Turn at milepost (MP) 6.89-7.05, Axle Bend <strong>Curve</strong> at MP 8.21-<br />

8.37, and Last <strong>Curve</strong> at MP 11.86-11.95. The purpose <strong>of</strong> the <strong>NM</strong> <strong>532</strong> <strong>Curve</strong> <strong>Correction</strong> <strong>Project</strong> is<br />

to improve safety conditions between MP 0.0 and MP 12.0 while considering the need <strong>of</strong> local<br />

residents, forest visitors, and the Mescalero Apache Tribe.<br />

<strong>Project</strong> Summary: Texas Turn, Axle Bend <strong>Curve</strong>, and Last <strong>Curve</strong> are proposed for extensive<br />

reconstruction based on their priority for improvements. Work would entail increasing the curve<br />

radii and correcting the curve grades. At each curve, a retained soil system (RSS) wall would be<br />

constructed using additional native fill. The RSS would consist <strong>of</strong> a geo-grid embankment<br />

constructed at a 0.5:1 slope with rock-filled baskets fro the wall face. Perforated drainpipes and<br />

subsurface drain outlets would be installed as part <strong>of</strong> the RSS wall. Guardrail would be installed at<br />

the top <strong>of</strong> the embankment. Energy dissipaters or other similar slope protection measures would be<br />

installed in areas where drainage has caused severe erosion. On the upslope side <strong>of</strong> Axle Bend<br />

<strong>Curve</strong>, some rock would be excavated and removed. No blasting would occur. Rock or slope<br />

protection would be used to create a stablized rock-cut face only if unstable rock is encountered.<br />

Environmental Assessment Availability: The environmental assessment will be available for<br />

review during a 30-day comment period beginning on March 15, 2013 and ending on April 15,<br />

<strong>NM</strong> <strong>532</strong> <strong>Curve</strong> <strong>Correction</strong> <strong>Project</strong> Environmental Assessment<br />

1.0 SUMMARY<br />

The <strong>New</strong> <strong>Mexico</strong> <strong>Department</strong> <strong>of</strong> Transportation (<strong>NM</strong>DOT), in cooperation with the Federal Highway<br />

Administration (FHWA), proposes to reconstruct three curves <strong>of</strong> the <strong>NM</strong> <strong>532</strong> roadway in Lincoln County,<br />

<strong>New</strong> <strong>Mexico</strong> (see Figure 1.1). <strong>NM</strong> <strong>532</strong> is a rural arterial roadway that extends from <strong>NM</strong> 48 in Alto to<br />

Ski Apache, and it provides the only roadway access to Ski Apache and nearby areas on the Lincoln<br />

National Forest. The project area is located within <strong>NM</strong>DOT District 2. The <strong>NM</strong> <strong>532</strong> <strong>Curve</strong> <strong>Correction</strong><br />

<strong>Project</strong> is listed in the Fiscal Year (FY) 2012-2015 Statewide Transportation Improvement Program<br />

(STIP) Amendment 4 as control number (CN) 2101140. The <strong>NM</strong> <strong>532</strong> <strong>Curve</strong> <strong>Correction</strong> <strong>Project</strong> EA was<br />

developed in accordance with the National Environmental Policy Act (NEPA), <strong>NM</strong>DOT Location Study<br />

Procedures (<strong>NM</strong>DOT, 2000) and Federal Highway Administration (FHWA) Technical Advisory T<br />

6640.8A, 23 Code <strong>of</strong> Federal Regulations (CFR) Parts 771 and 772, and other applicable guidelines and<br />

regulations.<br />

The purpose <strong>of</strong> the <strong>NM</strong> <strong>532</strong> <strong>Curve</strong> <strong>Correction</strong> <strong>Project</strong> is to improve traffic and safety conditions between<br />

MP 0.0 and MP 12.0 while considering the needs <strong>of</strong> local residents, forest visitors, and the Mescalero<br />

Apache Tribe. The project need is based on the following conditions: insufficient shoulder width;<br />

roadway geometry does not meet current standards resulting in several sharp curves; post-fire soil erosion<br />

undercuts the roadway, steep drop-<strong>of</strong>fs next to driving lanes; limited signage to inform drivers <strong>of</strong> roadway<br />

conditions; lack <strong>of</strong> pull-<strong>of</strong>f areas; poor pedestrian access at scenic areas; extensive maintenance needs;<br />

and economic viability <strong>of</strong> recreation-related businesses.<br />

The following three curves are proposed for extensive reconstruction: Texas Turn at MP 6.89-7.05, Axle<br />

Bend <strong>Curve</strong> at MP 8.21-8.37, and Last <strong>Curve</strong> at MP 11.86-11.95 (see Figure 1.2). These curves have<br />

been identified as priority for improvements. Work would entail increasing the curve radii and correcting<br />

the curve grades. At each curve, a retained soil system (RSS) wall would be constructed using additional<br />

native fill. The RSS would consist <strong>of</strong> a geo-grid embankment constructed at a 0.5:1 slope with rock-filled<br />

baskets for the wall face. Perforated drainpipes and subsurface drain outlets would be installed as part <strong>of</strong><br />

the RSS wall. Guardrail would be installed at the top <strong>of</strong> the embankment. Energy dissipaters or other<br />

similar slope protection measures would be installed in areas where drainage has caused severe erosion.<br />

On the upslope side <strong>of</strong> Axle Bend <strong>Curve</strong>, some rock would be excavated and removed. No blasting<br />

would occur. Rock or slope protection would be used to create a stabilized rock-cut face only if unstable<br />

rock is encountered.<br />

The current proposed typical section would consist <strong>of</strong> two 11-foot travel lanes, two 3-foot shoulders, and<br />

two 2.5 foot tapers. Existing vehicle pull-<strong>of</strong>f areas at each curve would be paved. In some areas, slopes<br />

would be excavated and additional fill would be placed. Walls, guardrails, and signs would be installed in<br />

some sections.<br />

The total estimated project cost for the Recommended Build Alternative is $1.8 million. Construction <strong>of</strong><br />

the project would begin in 2013.<br />

This EA concludes that the Recommended Build Alternative meets the purpose and need <strong>of</strong> the proposed<br />

project and is not expected to have significant adverse social, economic, or environmental impacts that<br />

will warrant an Environmental Impact Statement. Unless significant impacts are identified as a result <strong>of</strong><br />

public review, a Finding <strong>of</strong> No Significant Impact (FONSI) will be requested from FHWA. If a FONSI is<br />

issued, it will provide approval for final design and construction <strong>of</strong> <strong>NM</strong> <strong>532</strong> at Texas Turn at MP 6.89-<br />

7.05, Axle Bend <strong>Curve</strong> at MP 8.21-8.37, and Last <strong>Curve</strong> at MP 11.86-11.95.<br />

2.0 PURPOSE AND NEED, HISTORY, AND EXISTING CONDITIONS<br />

2.1 <strong>Project</strong> Purpose and Need<br />

The purpose <strong>of</strong> the <strong>NM</strong> <strong>532</strong> <strong>Curve</strong> <strong>Correction</strong> <strong>Project</strong> is to improve traffic and safety conditions between<br />

MP 0.0 and MP 12.0 while considering the needs <strong>of</strong> local residents, forest visitors, and the Mescalero<br />

Apache Tribe. The project need is based on the following conditions:<br />

• Insufficient shoulder width; roadway geometry does not meet current standards resulting in<br />

several sharp curves;<br />

• Post-fire soil erosion undercuts the roadway;<br />

• Steep drop-<strong>of</strong>fs next to driving lanes;<br />

• Limited signage to inform drivers <strong>of</strong> roadway conditions;<br />

• Lack <strong>of</strong> pull-<strong>of</strong>f areas;<br />

• Poor pedestrian access at scenic areas;<br />

• Extensive maintenance needs; and<br />

• Economic viability <strong>of</strong> recreation-related businesses.<br />

2.2 <strong>Project</strong> History<br />

Initially <strong>NM</strong> <strong>532</strong> was established as an unpaved road to provide access to Ski Apache, which opened in<br />

1961. The road was later paved in 1965 (Kidder and Brunell, 2009). During the next 40 years, the road<br />

was maintained, but no major improvements were constructed until 2008 when <strong>NM</strong>DOT constructed<br />

roadway and slope improvements in selected sections that were failing. In 2006, <strong>NM</strong>DOT initiated a<br />

corridor study to inventory existing conditions and development alternatives for improving access<br />

between the <strong>NM</strong> 48 intersection at MP 0.0 and Ski Apache at MP 12.0. <strong>NM</strong>DOT contracted with Smith<br />

Engineering Company (Smith) to prepare the corridor study. To obtain public input on the <strong>NM</strong> <strong>532</strong><br />

<strong>Curve</strong> <strong>Correction</strong> <strong>Project</strong>, <strong>NM</strong>DOT and Smith held a series <strong>of</strong> public meetings in Ruidoso during the fall<br />

2006 to identify and rank issues <strong>of</strong> concern. Local stakeholders including local residents, skiers, local<br />

businesses, Mescalero Apache Tribe, and Lincoln National Forest attended the meetings. The top four<br />

issues as ranked by stakeholders were:<br />

• Safety – risk <strong>of</strong> serious injury or death;<br />

• Safety – emergency medical services (EMS) response time to Ski Apache;<br />

• Local economy – increasing business at Ski Apache; and<br />

• Local economy – revenues <strong>of</strong> local businesses.<br />

The <strong>NM</strong> <strong>532</strong> Corridor Study recommended constructing a gondola between Eagle Lakes and Ski Apache<br />

and improving the existing <strong>NM</strong> <strong>532</strong> alignment as two viable alternatives. The Mescalero Apache Tribe<br />

subsequently received funding from the <strong>NM</strong>DOT to further develop these alternatives for moving the<br />

project forward. The Mescalero Apache Tribe intends to eventually identify a funding source and<br />

develop plans for constructing a gondola. Since gondola funding is not likely to be obtained in the next<br />

1-3 years, a decision was made to focus on improving <strong>NM</strong> <strong>532</strong> between MP 0.0 and MP 12.0 since such<br />

improvements would have a lower cost and have a higher probability <strong>of</strong> obtaining funding. In 2009 and<br />

2010, preliminary plans were prepared, and initial environmental studies were conducted for Texas Turn,<br />

Axle Bend <strong>Curve</strong>, and No Last <strong>Curve</strong>. In 2012, the plans and environmental studies were updated and are<br />

presented in this EA as the <strong>NM</strong> <strong>532</strong> <strong>Curve</strong> <strong>Correction</strong> <strong>Project</strong>. The Little Bear Fire burned many areas<br />

along the project area during the summer <strong>of</strong> 2012 (see Figure 2.1).<br />

2.3 Traffic Conditions<br />

<strong>NM</strong> <strong>532</strong> is an undivided two-lane roadway that extends from the <strong>NM</strong> 48 intersection in Alto to Ski<br />

Apache. The roadway section covered in this EA document extends from the <strong>NM</strong> 48 intersection at MP<br />

0.0 to Ski Apache at MP 12.0.<br />

<strong>NM</strong> <strong>532</strong> <strong>Curve</strong> <strong>Correction</strong> <strong>Project</strong> Environmental Assessment<br />

During most <strong>of</strong> the year, <strong>NM</strong> <strong>532</strong> has little traffic, and traffic flow is acceptable. Drivers tend to be<br />

cautious and drive slowly in response to the steep drop-<strong>of</strong>fs, difficult curves, and lack <strong>of</strong> sight distance<br />

and passing lanes. Drivers become especially cautious when the roadway is covered in ice and snow.<br />

Traffic increases during peak ski season. The average annualized traffic volume was 663 vehicles per day<br />

in 2007. During ski season, peak hour traffic can reach 1,298 vehicles per hour, and 20-year projections<br />

foresee peak hour traffic volumes <strong>of</strong> 3,200 vehicles per hour (Smith, 2008).<br />

Forty-eight crashes occurred along <strong>NM</strong> <strong>532</strong> from 2001 through 2005 based on police reports (see Table<br />

2.1). Additional crashes have occurred on <strong>NM</strong> <strong>532</strong> but were not reported to the police based on<br />

information provided by local residents. There have been no documented fatality crashes on <strong>NM</strong> <strong>532</strong>.<br />

Crash locations were dispersed along <strong>NM</strong> <strong>532</strong> although it appears that most crashes occurred at sharp<br />

curves or at the <strong>NM</strong> 48 intersection.<br />

2.4 Roadway Conditions<br />

<strong>NM</strong> <strong>532</strong> from MP 0.0 to MP 12.0 is characterized by steep grades and several sharp curves. <strong>NM</strong> <strong>532</strong> has<br />

a posted speed limit <strong>of</strong> 25 mph, but it does not meet current AASHTO design standards for this posted<br />

speed limit. The existing typical section consists <strong>of</strong> two travel lanes, varying in width from 11 to 12 feet.<br />

The roadway has narrow gravel shoulders <strong>of</strong> 0 to 2 feet in width. The lane widths are <strong>of</strong>ten further<br />

reduced during winter due to snowdrifts and piles <strong>of</strong> plowed snow. Steep drop-<strong>of</strong>f sections and rocky<br />

near-vertical cliffs exist outside the narrow shoulders, providing little to no room for emergency pull-<strong>of</strong>f<br />

areas.<br />

Adjoining slopes are rocky in many areas and some are unstable. Erosion as a result <strong>of</strong> the 2012 Little<br />

Bear Fire has undercut portions <strong>of</strong> the roadway. Shoulder space, guardrail, road striping, and clear zones<br />

are lacking along most <strong>of</strong> <strong>NM</strong> <strong>532</strong>. The 0-2 foot shoulders are next to either steep drop-<strong>of</strong>fs or vertical<br />

cliff sections. Except for the guardrail improvements constructed in 2008, most <strong>of</strong> the roadway guardrails<br />

do not meeting AASHTO standards. Many <strong>of</strong> the drainage culverts are not separated from the roadway<br />

with the minimal acceptable clear zone horizontal distance or guardrail. Any vehicle that accidentally<br />

leaves the roadway surface is likely to encounter a steep drop-<strong>of</strong>f, vertical cliff section, or drainage<br />

culvert.<br />

2.5 Drainage<br />

The <strong>NM</strong> <strong>532</strong> <strong>Project</strong> Area is located within the Eagle Creek and Rio Ruidoso watersheds <strong>of</strong> the Hondo<br />

basin. The steep slopes along <strong>NM</strong> <strong>532</strong> allow for good roadway drainage with little ponding <strong>of</strong> water.<br />

Some <strong>of</strong> the drainage structures need improvement.<br />

2.6 Right-<strong>of</strong>-way<br />

Most <strong>of</strong> the <strong>NM</strong>DOT right-<strong>of</strong>-way along <strong>NM</strong> <strong>532</strong> has limited available space for roadway widening<br />

because <strong>of</strong> steep slopes. The right-<strong>of</strong>-way is 132 feet wide on land used under a permit from the Lincoln<br />

National Forest. Lands bordering the right-<strong>of</strong>-way are owned by the Lincoln National Forest.<br />

<strong>NM</strong> <strong>532</strong> <strong>Curve</strong> <strong>Correction</strong> <strong>Project</strong> Environmental Assessment<br />

3.0 ALTERNATIVES CONSIDERED<br />

This section discusses the alternatives under consideration for meeting the project purpose and need. The<br />

alternatives were developed and refined during the development <strong>of</strong> preliminary project concepts and<br />

plans. The Recommended Build Alternative was carried through the environmental analysis discussed in<br />

Section 4.0 <strong>of</strong> this document.<br />

3.1 Alternatives Considered but Eliminated from Further Consideration<br />

<strong>New</strong> roadway alternatives were considered but eliminated because <strong>of</strong> their high costs, challenging<br />

constructability, and potential for substantial environmental damage with construction in active stream<br />

channels and undisturbed habitat (Smith, 2008). Construction <strong>of</strong> a gondola is still considered a viable<br />

alternative, but no funding for a gondola is expected to be identified or available within the foreseeable<br />

future.<br />

3.2 No-Build Alternative<br />

Under the No Build Alternative, roadway improvements would not be constructed. Sharp curves would<br />

not be modified. The roadway would not be reconstructed. No guardrail would be added. Safety<br />

concerns related to the sharp curves and steep drop-<strong>of</strong>fs without guardrail would continue. <strong>NM</strong>DOT<br />

would continue to implement a high level <strong>of</strong> maintenance in order to keep <strong>NM</strong> <strong>532</strong> functional. The<br />

average annual maintenance cost for the curves has been approximately $6,000.<br />

3.3 Recommended Build Alternative<br />

Roadway<br />

The existing roadway would be reconstructed from the BIA 21 / Eagle Lakes intersection at MP 0.0 to the<br />

Ski Apache entrance at MP 12.0. The design speed would be 40 mph. Sharp curves and steep grade<br />

sections would have a 20-35 mph design speed. The posted speed limit would be 35 mph and 15-30 mph<br />

at sharp curves and steep grades. The typical section would consist <strong>of</strong> two 11-foot travel lanes, two 3-<br />

foot paved shoulders, and two 2.5-foot tapers. In some areas, additional fill would be excavated <strong>of</strong>f-site<br />

and placed for the proposed typical section. RSS walls, guardrail, and signage would be installed in<br />

some sections.<br />

<strong>Curve</strong>s<br />

The following three curves are proposed for extensive reconstruction: Texas Turn at MP 6.89-7.05, Axle<br />

Bend <strong>Curve</strong> at MP 8.21-8.37, and Last <strong>Curve</strong> at MP 11.86-11.95 (see Figures 3.1-3.3). Work would<br />

entail increasing the curve radii and correcting the curve grades. At each curve, a retained soil system<br />

(RSS) wall would be constructed using additional native fill. The RSS would consist <strong>of</strong> a geo-grid<br />

embankment constructed at a 0.5:1 slope with rock-filled baskets for the wall face. Perforated drainpipes<br />

and subsurface drain outlets would be installed as part <strong>of</strong> the RSS wall. Guardrail would be installed at<br />

the top <strong>of</strong> the embankment. Energy dissipaters or other similar slope protection measures would be<br />

installed in areas where drainage has caused severe erosion. On the upslope side <strong>of</strong> Axle Bend <strong>Curve</strong>,<br />

some rock would be excavated and removed. No blasting would occur. Rock or slope protection would<br />

be used to create a stabilized rock-cut face only if unstable rock is encountered. Paved parking areas/pull<br />

<strong>of</strong>fs would be constructed at Texas Turn and Last <strong>Curve</strong>.<br />

Drainage<br />

Drainage structures would be repaired to improve drainage at Last <strong>Curve</strong>, and rip-rap would be installed<br />

in some areas. At the three curves, perforated drainpipes and subsurface drain outlets would be installed<br />

as part <strong>of</strong> the RSS wall.<br />

Right-<strong>of</strong>-way<br />

<strong>NM</strong>DOT would continue to utilize its U.S. Forest Service permitted right-<strong>of</strong>-way along <strong>NM</strong> <strong>532</strong>. No<br />

additional right-<strong>of</strong>-way would be needed at the curves.<br />

Construction and Sequencing<br />

The reconstruction <strong>of</strong> the three curves would be constructed in a single phase. Construction would begin<br />

in 2013.<br />

4.0 AFFECTED ENVIRO<strong>NM</strong>ENT<br />

This section describes the existing environmental conditions in the project area, evaluates the impacts <strong>of</strong><br />

the proposed action, and suggests mitigation measures for any environmental impacts that cannot be<br />

avoided.<br />

The No-Build Alternative does not meet the project need, and in general, has little effect on most<br />

components <strong>of</strong> the existing environment. Drainage structures would continue to become silted in with<br />

reduced effective drainage. The ability <strong>of</strong> the roadway to serve local residents may decrease as roadway<br />

conditions deteriorate. The remainder <strong>of</strong> this section evaluates the Recommended Build Alternative<br />

described in Section 3.0.<br />

4.1 General <strong>Project</strong> Setting<br />

The Recommended Build Alternative project area is located in Lincoln County, <strong>New</strong> <strong>Mexico</strong> (see Figures<br />

1.1 and 1.2). The project area covers approximately 10.0 acres with approximately 6 acres <strong>of</strong> vegetation<br />

disturbance proposed. <strong>NM</strong>DOT has a permitted right-<strong>of</strong>-way within the Lincoln National Forest.<br />

4.2 Landforms and Geology<br />

Existing Conditions – Volcanic activity created many <strong>of</strong> the geologic and topographic features <strong>of</strong> the<br />

Sierra Blanca region. Sierra Blanca is a composite volcano that erupted about 35 million years ago<br />

(Chronic, 1987). The <strong>NM</strong> <strong>532</strong> <strong>Project</strong> Area is located in the Sacramento Section <strong>of</strong> the Basin and Range<br />

Physiographic Province (Williams, 1986). Elevation ranges from 7319 feet above mean sea level (amsl)<br />

at the <strong>NM</strong> 48 / <strong>NM</strong> <strong>532</strong> junction to 10,080 feet along <strong>NM</strong> <strong>532</strong> between Windy Point and Ski Apache Ski<br />

Area. Principal geologic formations in the project area are Middle Tertiary volcanic rocks and Tertiary<br />

intrusive rocks (<strong>New</strong> <strong>Mexico</strong> Bureau <strong>of</strong> Geology and Mineral Resources, 2003).<br />

Potential Effects and Mitigation Measures – Correcting design deficiencies would be costly because<br />

<strong>of</strong> steep slopes and uneven topography. As with the No Build Alternative, steep grades and sharp curves<br />

March 2013 9 CN 2101140


<strong>NM</strong> <strong>532</strong> <strong>Curve</strong> <strong>Correction</strong> <strong>Project</strong> Environmental Assessment<br />

create challenging driving conditions. Along the existing alignment, the average grade <strong>of</strong> 8% would<br />

remain the same except for minor modifications at curves. Extensive cut and fill construction activities<br />

would be completed to correct curve geometrics, roadway grade, and slope stability conditions at the<br />

Texas Turn, Axle Bend <strong>Curve</strong>, and Last <strong>Curve</strong>. Rock or slope protection would be used to create a<br />

stabilized rock-cut face only if unstable rock is encountered. Rock would be excavated mechanically<br />

without the use <strong>of</strong> explosives. RSS wall with rock-filled baskets would be installed at the curves. Less<br />

long-term maintenance would be required.<br />

4.3 Soils<br />

Existing Conditions – Soils in the <strong>NM</strong> <strong>532</strong> <strong>Project</strong> Area are not well mapped. In general, the soils range<br />

from deeper alluvial soils in valley bottoms to shallower, rocky soils on mountains side and ridge tops.<br />

Because <strong>of</strong> the steeps slopes in many areas, the soils are subject to erosion, slippage, and landslides when<br />

vegetation is removed.<br />

Potential Effects and Mitigation Measures – During construction activities, soil excavation and<br />

disturbance would occur. Approximately 10 acres would be affected. A Stormwater Pollution Prevention<br />

Plan (SWPPP) containing Best Management Practices (BMPs) to reduce erosion would be prepared prior<br />

to construction. Slope stabilization and drainage improvements would improve water quality through the<br />

reduction <strong>of</strong> erosion and sediment transport.<br />

4.4 Surface and Ground Water<br />

Existing Conditions – The <strong>NM</strong> <strong>532</strong> <strong>Project</strong> Area is located within the Eagle Creek and Rio Ruidoso<br />

watersheds <strong>of</strong> the Hondo basin. The North Fork <strong>of</strong> the Rio Ruidoso has headwaters in the western part <strong>of</strong><br />

the project area. Eagle Creek, south <strong>of</strong> <strong>NM</strong> <strong>532</strong>, is a tributary <strong>of</strong> the Rio Ruidoso, which empties into the<br />

Rio Hondo near the town <strong>of</strong> Hondo. A few drainage crossings may be jurisdictional waters subject to<br />

Section 404 permits. Stream flows in Eagle Creek below South Fork can range from less than 1000 acrefeet<br />

to 4000 acre-feet per year (Donohoe, 2004). Development is increasing the demand for surface and<br />

ground water in the Ruidoso area. The 100-year floodplains are not well mapped in this area (Federal<br />

Insurance Administration, 1977). The project area has an upland location and flooding is not a concern.<br />

Potential Effects and Mitigation Measures – Reconstruction <strong>of</strong> the curves would correct drainage<br />

issues at those locations; however, the existing drainage problems at other sections along <strong>NM</strong> <strong>532</strong> would<br />

persist. Construction at Last <strong>Curve</strong> would not involve modification to the existing drainage culvert or<br />

work within the Rio Ruidoso. Under current design, Section 404 permitting from the U.S. Army Corps <strong>of</strong><br />

Engineers (USACE) and Section 401 permitting from the <strong>New</strong> <strong>Mexico</strong> Environment <strong>Department</strong><br />

(<strong>NM</strong>ED) would not be necessary. Wetlands at Last <strong>Curve</strong> are discussed under wetlands in the next<br />

section. Since the area <strong>of</strong> disturbance exceeds one acre, the construction contractor will prepare a SWPPP<br />

as part <strong>of</strong> obtaining coverage under a National Pollutant Discharge Elimination System (NPDES) general<br />

construction activity permit. The SWPPP will include BMPs to minimize soil erosion and sediment<br />

transport including mitigation measures to protect water quality. Temporary erosion and sediment control<br />

plans will be included in the plan sets. Slope stabilization and drainage improvements would improve<br />

water quality through the reduction <strong>of</strong> erosion and sediment transport.<br />

4.5 Wetlands<br />

Existing Conditions – Wetlands are identified by vegetation, soil, and hydrologic indicators diagnostic<br />

<strong>of</strong> wetland conditions as defined in the 1987 Corps <strong>of</strong> Engineers Wetland Delineation Manual (USACE,<br />

1987). Wetlands are present outside <strong>of</strong> the project area at Last <strong>Curve</strong>.<br />

Potential Effects and Mitigation Measures – No wetlands are present at Texas Turn or Axle Bend<br />

<strong>Curve</strong>, but wetlands are adjacent to Last <strong>Curve</strong>. Construction activities will avoid the wetlands at Last<br />

<strong>Curve</strong>. Temporary fencing will be constructed around the wetlands to keep construction activities away<br />

from the wetlands.<br />

<strong>NM</strong> <strong>532</strong> <strong>Curve</strong> <strong>Correction</strong> <strong>Project</strong> Environmental Assessment<br />

4.6 Vegetation<br />

Existing Conditions –The major vegetation types are montane coniferous forest, subalpine coniferous<br />

forest, and montane grassland. Montane coniferous woodland has a tree canopy with dominant species<br />

consisting <strong>of</strong> ponderosa pine, Douglas fir, and white fir. Subalpine coniferous forest occurs at higher<br />

elevations than the montane coniferous woodland and has a tree canopy with dominant species consisting<br />

<strong>of</strong> corkbark fir and Engelmann Spruce. Montane grassland grows in open areas without a tree canopy<br />

and is dominated by grasses such as Thurber fescue, Arizona fescue, and Kentucky bluegrass. Large<br />

areas <strong>of</strong> gambel oak thickets are also present in the project area. Portions <strong>of</strong> the project area were burned<br />

in the 2012 Little Bear Fire (see Figures 2.1, 4.1, and 4.2).<br />

Potential Effects and Mitigation Measures – Vegetation disturbance would occur at cut and fill areas<br />

and other roadside areas. Approximately 6 acres <strong>of</strong> vegetation would be affected.<br />

4.7 Fish and Wildlife<br />

Existing Conditions – High quality wildlife habitat occurs along the <strong>NM</strong> <strong>532</strong> <strong>Project</strong> Area. The mixture<br />

<strong>of</strong> forest cover, open grasslands, and riparian areas with good water sources results in relatively high<br />

wildlife populations. Both elk and mule deer have large populations and are easily observed. Black bear,<br />

coyote, striped skunk, and a wide variety <strong>of</strong> small mammals are present. The mixture <strong>of</strong> forested and<br />

open areas with easily accessible water sources provide good bird habitat. Important fish habitat occurs<br />

downstream <strong>of</strong> the project area in the North Fork <strong>of</strong> the Rio Ruidoso, Eagle Creek, and Eagle Lakes.<br />

Potential Effects and Mitigation Measures – Wildlife habitat disturbance would occur at cut and fill<br />

areas in the <strong>NM</strong> <strong>532</strong> <strong>Project</strong> Area, affecting approximately 6 acres. Any tree cutting or shrub clearing<br />

would occur outside <strong>of</strong> the migratory bird nesting season (March 1 through August 30), or a nesting<br />

survey would be completed prior to tree cutting. Wildlife would be temporarily disturbed during<br />

construction. BMPs would be needed to ensure protection <strong>of</strong> fish habitat water quality during and after<br />

construction. Improved drainage would reduce erosion and sediment transport resulting in improved<br />

water quality.<br />

4.8 Threatened and Endangered Species<br />

Existing Conditions – Three protected species are known to occur along <strong>NM</strong> <strong>532</strong>. The Mexican spotted<br />

owl is listed as a threatened species under the Endangered Species Act. Designated critical habitat for<br />

the Mexican spotted owl is located adjacent to <strong>NM</strong> <strong>532</strong>. Owls are present in the Carlton protected<br />

activity center (PAC), which is adjacent to the <strong>NM</strong> <strong>532</strong> <strong>Project</strong> Area at Texas Turn. The Sacramento<br />

Mountain salamander occurs near Last <strong>Curve</strong>. The salamander is classified as a federal species <strong>of</strong><br />

concern, state threatened, and Forest Service sensitive species. <strong>New</strong> <strong>Mexico</strong> stonecrop, a Forest Service<br />

sensitive species, occurs at locations outside <strong>of</strong> the project area along <strong>NM</strong> <strong>532</strong>.<br />

Potential Effects and Mitigation Measures – Renovation <strong>of</strong> the existing alignment would have no<br />

effect on federal, state, and U.S. Forest Service listed endangered, threatened, and sensitive protected<br />

species. Specific mitigation and avoidance measures have been developed for threatened and endangered<br />

species and are listed in Table 6.1. These measures are focused on the Mexican spotted owl and<br />

Sacramento Mountain salamander. With these measures, the project would have no effect on the<br />

Mexican spotted owl since construction activities will be restricted at Texas Turn between March 1 and<br />

August 30 to mitigate potential impacts to the Mexican spotted owl. The project may affect, not<br />

adversely affect the Sacramento Mountain salamander. The project would have no effect on other federal<br />

and state threatened and endangered species.<br />

4.9 Cultural Resources<br />

Existing Conditions – Pursuant to Section 106 <strong>of</strong> the National Historic Preservation Act (16 USC 470),<br />

<strong>NM</strong>DOT and FHWA are required to evaluate the potential impacts <strong>of</strong> the proposed project on cultural<br />

resources listed or eligible for listing on the National Register <strong>of</strong> Historic Places (NRHP). Cultural<br />

resource eligibility and potential for adverse effects are evaluated in consultation with the State Historic<br />

Preservation Officer (SHPO) at the <strong>New</strong> <strong>Mexico</strong> Historic Preservation Division. A cultural resource<br />

study inventoried and evaluated cultural resources within the project area. No archaeological sites or<br />

historic properties were found in the project area.<br />

Potential Impacts and Mitigation Measures – No archaeological sites or historic properties would be<br />

affected by the Recommended Build Alternative. <strong>NM</strong>DOT has obtained concurrence from the State<br />

Historic Preservation Officer (SHPO) for this determination.<br />

4.10 Climate and Air Quality<br />

Existing Conditions – The climate in the <strong>NM</strong> <strong>532</strong> <strong>Project</strong> Area has mild summers and cold winters.<br />

Based on 30-year records, the average annual temperature in Ruidoso is 49.2 degrees Fahrenheit (°F)<br />

(National Climatic Data Center, 2002). Average maximum temperatures range from 49.5 °F in January to<br />

81.5 °F in June. Average minimum temperatures range from 19.8 °F in January to 48.6 °F in July.<br />

Ruidoso’s average annual rainfall is 22.71 inches and ranges from 0.68 inches in April to 4.40 inches in<br />

August. Because <strong>of</strong> its higher elevation, the <strong>NM</strong> <strong>532</strong> <strong>Project</strong> Area experiences cooler temperatures and<br />

more precipitation than Ruidoso.<br />

The Clean Air Act established National Ambient Air Quality Standards (NAAQS) for the following<br />

criteria pollutants: carbon monoxide, ozone, nitrogen dioxide, sulfur dioxide, lead, and airborne<br />

particulates. Lincoln County is in attainment with the NAAQS. With few emission sources, air quality is<br />

excellent at the project area. The issue <strong>of</strong> global climate change is an important national and global<br />

concern that is being addressed by the federal and state governments. The transportation sector is the<br />

second largest source <strong>of</strong> total greenhouse gases (CHGs) in the United States and the largest source <strong>of</strong><br />

carbon dioxide emissions, the predominant CHG. Almost all (98 percent) <strong>of</strong> transportation-sector<br />

emissions result from the consumption <strong>of</strong> petroleum products such as gasoline, diesel fuel, and aviation<br />

fuel. FHWA is working nationally with other agencies through the <strong>Department</strong> <strong>of</strong> Transportation Center<br />

for Climate Change and Environmental Forecasting.<br />

Potential Effects and Mitigation Measures – The Recommended Build Alternative would have no<br />

long-term impact on air quality. Vehicle air emissions are not expected to increase as a result <strong>of</strong> the<br />

proposed roadway improvements. Regional air quality is not expected to change, and the project would<br />

have little effect on global climate change trends. The Council on Environmental Quality guidance<br />

requires federal agencies to consider how proposed federal actions could affect sources and sinks <strong>of</strong><br />

greenhouse gases and how climate change could potentially be affected. <strong>NM</strong>DOT is studying energy<br />

consumption and CHG emissions from <strong>New</strong> <strong>Mexico</strong>’s transportation sector. Because climate change is a<br />

global issue and emissions changes due to the Recommended Build Alternative would be very small<br />

compared to global totals, the CHG emissions associated with the Recommended Build Alternative were<br />

not calculated. Short-term dust impacts would occur during construction. Dust control mitigation<br />

measures are recommended during construction as specified in <strong>NM</strong>DOT Standard Specifications for<br />

Highway and Bridge Construction, 1017.14.5 Air Quality Requirements and Dust Abatement.<br />

4.11 Noise<br />

Existing Conditions – <strong>NM</strong>DOT noise policies and procedures are based on FHWA noise regulations and<br />

are specified in the <strong>NM</strong>DOT Infrastructure Design Directive IDD-2011-02, Procedures for Abatement <strong>of</strong><br />

Highway Traffic Noise and Construction Noise. Most <strong>of</strong> the area near the <strong>NM</strong> <strong>532</strong> <strong>Project</strong> Area is<br />

undeveloped. No residences, schools, or hospitals are located within 1.0 mile <strong>of</strong> the project area. Noise<br />

from the roadway is audible at the Oak Grove and Eagle Lakes campgrounds and Ski Apache.<br />

March 2013 13 CN 2101140


<strong>NM</strong> <strong>532</strong> <strong>Curve</strong> <strong>Correction</strong> <strong>Project</strong> Environmental Assessment<br />

Potential Impacts and Mitigation Measures – According to <strong>NM</strong>DOT’s noise policy, noise abatement<br />

must be considered when predicted traffic noise levels for a particular land use "approach" or exceed the<br />

noise level threshold defined for its activity category, which is 67 decibels (dBA) for land uses near the<br />

project area. Noise abatement must also be considered when a roadway project results in a substantial<br />

increase over existing noise levels. A 10 decibel increase is considered a substantial increase over<br />

existing noise levels. The Recommended Build Alternative would not produce increased noise levels<br />

since traffic is not expected to increase substantially as a result <strong>of</strong> the Recommended Build Alternative.<br />

4.12 Visual Resources<br />

Existing Conditions - The <strong>NM</strong> <strong>532</strong> <strong>Project</strong> Area has high visual quality. Views from the roadway <strong>of</strong><br />

Sierra Blanca and nearby peaks are distinctive landmarks valued by local residents and visitors. The<br />

attractive mountainous and forested landscapes near the project area contribute to the area’s high<br />

recreation value. Key viewpoints along <strong>NM</strong> <strong>532</strong> include the Windy Point Vista and the Ski Apache<br />

resort.<br />

Potential Effects and Mitigation Measures – The Recommended Build Alternative would result in<br />

minimal modification <strong>of</strong> existing visual resources. The new cut and fill locations would clear currently<br />

forested areas and result in minor visual modifications between MP 0.0 and MP 12.0. Proposed road<br />

improvements would affect the road surface and shoulders but not substantially increase the amount <strong>of</strong><br />

visible rock face or exposed road fill. The cut and fill areas at Texas Turn, Axle Bend <strong>Curve</strong>, and Last<br />

<strong>Curve</strong> would result in moderate visual modifications. Increased areas <strong>of</strong> rock face and RSS wall would<br />

be visible. The high quality views <strong>of</strong> the night sky would not be changed and would comply with the<br />

<strong>New</strong> <strong>Mexico</strong> Night Sky Protection Act.<br />

4.13 Communities and Land Use<br />

Existing Conditions – <strong>NM</strong> <strong>532</strong> is located within the Lincoln National Forest. The forest covers<br />

approximately 1,103,629 acres with 87% <strong>of</strong> the land classified as forest and 13% as nonforest (Shaw,<br />

2006). National forest lands are managed for multiple uses including recreation, wildlife, timber, forest<br />

fire control, livestock grazing, watershed protection, and wilderness. The Smokey Bear Ranger District,<br />

based in Ruidoso, manages the portion <strong>of</strong> the Lincoln National Forest along <strong>NM</strong> <strong>532</strong>. Alto is located<br />

approximately 2.0 miles east <strong>of</strong> the project area and is the closest community to the project area. Ruidoso<br />

and Village <strong>of</strong> Ruidoso Downs, located about 4-8 miles southeast <strong>of</strong> the project area, are the main<br />

regional communities. These communities are where the majority <strong>of</strong> regional residents reside and include<br />

most <strong>of</strong> the region’s commercial establishments.<br />

Potential Effects and Mitigation Measures – The Recommended Build Alternative would not change<br />

the undeveloped, rural character <strong>of</strong> lands along <strong>NM</strong> <strong>532</strong>. Roadway improvements would improve driving<br />

conditions <strong>of</strong> travelers to Oak Grove campground, Windy Point Vista, the trailhead at Last <strong>Curve</strong>, and Ski<br />

Apache.<br />

4.14 Socioeconomics and Environmental Justice<br />

Existing Conditions – An analysis <strong>of</strong> social impacts includes a consideration <strong>of</strong> disproportionate impacts<br />

on particular population groups, loss <strong>of</strong> community cohesion, changes in accessibility to facilities or<br />

services, and the displacement <strong>of</strong> people. Economic impacts include effects on business viability,<br />

employment, the local tax base, and factors that are relevant to local economic conditions.<br />

Lincoln County is a rural county with a mixture <strong>of</strong> private and Lincoln National Forest lands. Lincoln<br />

County had a population <strong>of</strong> 20,497 in 2010, which is projected to increase to 24,640 by 2030 (see Table<br />

4.1). Lincoln County’s projected growth rate is 0.73%, which is lower than the state growth rate <strong>of</strong><br />

1.72%. Census Tract 9604 that covers the project area and surrounding region had a 2010 population <strong>of</strong><br />

6,771.<br />

During the years 2006-2010, Lincoln County incomes were slightly above the state median family and<br />

per capita incomes. Median family income in Lincoln County was $53,871, and per capita income was<br />

$24,290. The state’s median family income was $52,565, and the per capita income was $22,966. The<br />

poverty rates had a corresponding pattern with a 12.9% individual poverty rate in Lincoln County versus<br />

a higher 18.4% individual statewide poverty rate.<br />

Potential Effects and Mitigation Measures - The Recommended Build Alternative is not expected<br />

to result in population growth or large-scale migration near the project area. The alternative is expected<br />

to have no effect on populations and incomes in Lincoln County and area communities. There would be a<br />

slight reduction in travel time to Ski Apache and improved safety. Providing a safer <strong>NM</strong> <strong>532</strong> roadway<br />

may increase tourist visits to Ski Apache and the Lincoln National Forest, especially during the winter.<br />

Increased tourist visitation at Ski Apache and Lincoln National Forest may indirectly benefit the regional<br />

economy. The project would not have negative impacts on business viability, employment, or the local<br />

tax base.<br />

Hispanic/Latino is the largest minority group representing 46.3% <strong>of</strong> the population in <strong>New</strong> <strong>Mexico</strong>,<br />

29.8% in Lincoln County, and 36.4% in Census Tract 9604. Native Americans represent 2.4% and<br />

African Americans represent 0.5% <strong>of</strong> the Lincoln County’s population. In terms <strong>of</strong> environmental justice,<br />

the Recommended Build Alternative would not disproportionately impact any identified environmental<br />

justice populations including low income or minority communities.<br />

4.15 Section 4(f) Properties<br />

Existing Conditions – As part <strong>of</strong> the Section 4(f) requirements, FHWA evaluates projects for impacts on<br />

public parks, recreation areas, wildlife and waterfowl refuges, and historic sites. FHWA projects are<br />

required to avoid such lands unless there is no prudent and feasible alternative to using that land. If such<br />

lands are used, the project must take steps to minimize harm to the land. Potential Section 4(f) properties<br />

are located at the Eagle Lakes campground operated by the Mescalero Apache tribe, Windy Point<br />

Overlook, and Oak Grove campground.<br />

March 2013 15 CN 2101140


<strong>NM</strong> <strong>532</strong> <strong>Curve</strong> <strong>Correction</strong> <strong>Project</strong> Environmental Assessment<br />

Potential Effects and Mitigation Measures – No Section 4(f) properties would be used by the<br />

Recommended Build Alternative. The Recommended Build Alternative would not use the Eagle Lakes<br />

campground or Oak Grove campground.<br />

4.16 Wilderness and Protected Areas<br />

Existing Conditions – Reserved lands, such as wilderness, are areas that are not designated for<br />

development, road construction, or timber harvesting. Eight percent <strong>of</strong> the Lincoln National Forest is<br />

designated as reserved lands (Shaw, 2006). The 48,873-acre White Mountain Wilderness Area is located<br />

near MP 11.9. This wilderness area was first designated as a 25,000 acre Primitive Area by Congress in<br />

1933 and added to the National Wilderness System in 1964 with additional acreage added in 1980<br />

(Lincoln National Forest, 2007). The White Mountain Wilderness Area can be accessed from <strong>NM</strong> <strong>532</strong><br />

near Last <strong>Curve</strong> via Lookout Trail 78 or Scenic Trail 15.<br />

Potential Effects and Mitigation Measures – The Recommended Build Alternative would not affect<br />

any wilderness or other protected areas. Indirect impacts could occur to the White Mountain Wilderness<br />

if transportation improvements resulted in increased hikers through this wilderness area.<br />

4.17 Farmland<br />

Existing Conditions – No cultivated farmland occurs within or adjoins the <strong>NM</strong> <strong>532</strong> <strong>Project</strong> Area.<br />

Adjoining lands are too steep and rocky for crop production.<br />

Potential Impacts and Proposed Mitigation Measures – No prime farmland or farmland <strong>of</strong> statewide<br />

importance would be affected by the Recommended Build Alternative.<br />

4.18 Right-<strong>of</strong>-way<br />

Existing Conditions – The <strong>NM</strong>DOT has a 132-foot wide right-<strong>of</strong>-way along <strong>NM</strong> <strong>532</strong> under permit with<br />

the Lincoln National Forest.<br />

Potential Impacts and Proposed Mitigation Measures – No additional right-<strong>of</strong>-way would be needed<br />

at the three curves.<br />

4.19 Multi-Modal Transportation<br />

Existing Conditions – Pedestrian, bicycle, equestrian, and transit opportunities are present in the <strong>NM</strong><br />

<strong>532</strong> <strong>Project</strong> Area. Pedestrians tend to use hiking trails on the Lincoln National Forest, but pedestrians<br />

occasionally walk along short segments <strong>of</strong> <strong>NM</strong> <strong>532</strong>. Bicyclists will occasionally ride along <strong>NM</strong> <strong>532</strong>.<br />

The narrow roadway and sharp curves create some potential for conflicts with vehicles. The need to<br />

improve bicycle opportunities has been identified in public meetings. Equestrian use is primarily <strong>of</strong>f <strong>of</strong><br />

<strong>NM</strong> <strong>532</strong> along hiking trails and on the Mescalero Apache Reservation and Lincoln National Forest.<br />

Equestrian use increases during the summer tourist season and fall hunting season. Shuttle buses<br />

transport skiers from hotels in Ruidoso and Ruidoso Downs to Ski Apache. Increased use <strong>of</strong> transit to<br />

transport skiers as well as summer tourists is possible but would likely require funding assistance.<br />

Potential Impacts and Proposed Mitigation Measures – Multi-modal opportunities would improve.<br />

Roadway improvements would provide pedestrians and bicyclists with more shoulder space. The<br />

proposed improvements would be minor and pedestrians and bicyclists would still need to share the road<br />

in some areas. Equestrians would have access to nearby areas but use <strong>of</strong> <strong>NM</strong> <strong>532</strong> would be very limited.<br />

The shuttle bus service would continue and have opportunities to develop increased service.<br />

4.20 Recreation<br />

Existing Conditions – The Lincoln National Forest areas near <strong>NM</strong> <strong>532</strong> have much recreation use<br />

including skiing, hiking, camping, hunting, fishing, and wildlife watching. Ski Apache is also located on<br />

the Lincoln National Forest. <strong>NM</strong> <strong>532</strong> is the only road to Ski Apache, operated by the Mescalero Apache<br />

Tribe. In addition to the ski area, other popular recreation destinations are located along this roadway<br />

including the Lincoln National Forest, fishing areas along Eagle Creek, and Windy Point Vista. Several<br />

March 2013 16 CN 2101140


<strong>NM</strong> <strong>532</strong> <strong>Curve</strong> <strong>Correction</strong> <strong>Project</strong> Environmental Assessment<br />

campgrounds have access <strong>of</strong>f <strong>of</strong> <strong>NM</strong> <strong>532</strong> including the Eagle Creek Campground operated by the<br />

Mescalero Apache Tribe and three U.S. Forest Service campgrounds: Monjeau, Oak Grove, and Skyline<br />

campgrounds. As mentioned above, tourism is an important component <strong>of</strong> the regional economy.<br />

Potential Effects and Mitigation Measures – The Recommended Build Alternative would have no<br />

impact on recreation. Improvements to <strong>NM</strong> <strong>532</strong> would improve safety conditions for travelers to<br />

recreation destinations. No recreation areas would be directly impacted by improvements to <strong>NM</strong> <strong>532</strong>.<br />

4.21 Hazardous Substances<br />

Existing Conditions - Hazardous materials are defined by the Hazardous Materials Transportation Act as<br />

substances or materials that when transported in commerce may create a risk to health, safety, and<br />

property. Additional hazardous substances are covered under the Comprehensive Environmental<br />

Response, Compensation, and Liability Act (CERCLA). In addition, the presence <strong>of</strong> petroleum products<br />

are considered, since hazardous materials or petroleum products present in the project area would be a<br />

serious concern to workers’ health and safety, as well as potential cleanup liability.<br />

The <strong>NM</strong> <strong>532</strong> <strong>Project</strong> Area appears to be free <strong>of</strong> hazardous materials issues. Preliminary records reviews<br />

and field surveys have not located any hazardous materials sites such as abandoned mines, service<br />

stations, landfills, illegal dumps sites, or industrial facilities.<br />

Potential Effects and Proposed Mitigation Measures – No hazardous materials issues have been<br />

identified at the project area or adjoining lands. During construction, the construction contractor will be<br />

responsible for managing hazardous substances in compliance with federal and state laws to ensure that<br />

no contamination occurs.<br />

4.22 Cumulative Impacts<br />

Cumulative impacts are defined as the impact that results from the incremental impact <strong>of</strong> an action when<br />

added to other past, present, and reasonably foreseeable future actions regardless <strong>of</strong> what agency or<br />

person undertakes such other actions. Cumulative impacts can also result from individually minor but<br />

collectively significant actions taking place over a period <strong>of</strong> time. No projects are planned within or<br />

adjacent to the <strong>NM</strong> <strong>532</strong> <strong>Project</strong> Area. In future years, periodic improvements will be made to facilities<br />

and ski lifts at Ski Apache. Conceptual plans have been developed for a gondola that would connect<br />

Eagle Lakes with Ski Apache. Buildings, parking areas, and a gondola station would be constructed at<br />

Eagle Lakes, and a gondola station would be constructed at the base <strong>of</strong> Ski Apache. Extensive<br />

environmental and engineering studies along with agency coordination would be conducted prior to<br />

constructing the gondola and ancillary facilities. In the Ruidoso region, residences would continue to be<br />

constructed on residential lots, and new businesses would locate in Ruidoso and Ruidoso Downs. Local<br />

governments would construct infrastructure to serve these residences and businesses. No other projects<br />

that affect the natural environment near the <strong>NM</strong> <strong>532</strong> <strong>Project</strong> Area have been identified.<br />

4.23 Indirect Impacts<br />

Indirect impacts are defined as indirect effects that are caused by an action later in time or further<br />

removed in distance but that are still reasonably foreseeable. Indirect effects may include growthinducing<br />

effects and other effects related to changes in land use, population density or growth rate, and<br />

the natural environment. The Recommended Build Alternative is not expected to result in any changes to<br />

regional land use, population density, growth rate, or the natural environment. No growth as a result <strong>of</strong><br />

the project is anticipated in nearby communities. Indirect impacts could occur to the White Mountain<br />

Wilderness if transportation improvements resulted in increased hikers through the White Mountain<br />

Wilderness.<br />

4.24 Conclusions<br />

This EA concludes that the Recommended Build Alternative meets the purpose and need <strong>of</strong> the proposed<br />

project and is not expected to have significant adverse social, economic, or environmental impacts that<br />

March 2013 17 CN 2101140


<strong>NM</strong> <strong>532</strong> <strong>Curve</strong> <strong>Correction</strong> <strong>Project</strong> Environmental Assessment<br />

will warrant an Environmental Impact Statement. Unless significant impacts are identified as a result <strong>of</strong><br />

public review, a Finding <strong>of</strong> No Significant Impact (FONSI) will be requested from FHWA. If a FONSI is<br />

issued, it will provide approval for final design and construction <strong>of</strong> <strong>NM</strong> <strong>532</strong> at Texas Turn at MP 6.89-<br />

7.05, Axle Bend <strong>Curve</strong> at MP 8.21-8.37, and Last <strong>Curve</strong> at MP 11.86-11.95.<br />

5.0 PUBLIC INVOLVEMENT<br />

5.1 Public Involvement and Local Coordination<br />

Seven public meetings have been held starting in September 2006. Many <strong>of</strong> the meetings focused on<br />

developing new roadway alternatives and possibly a gondola. The meeting held in December 2009 was<br />

focused more on improvements to the existing <strong>NM</strong> <strong>532</strong>. At this meeting, improvements to Texas Turn,<br />

Axle Bend <strong>Curve</strong>, and Last <strong>Curve</strong> were identified as priorities.<br />

5.2 Agency Coordination<br />

<strong>NM</strong>DOT has coordinated with several agencies. Representatives from the Mescalero Apache Tribe and<br />

Smokey Bear Ranger District <strong>of</strong> the Lincoln National Forest participated in project planning. The<br />

USFWS and <strong>New</strong> <strong>Mexico</strong> <strong>Department</strong> <strong>of</strong> Game and Fish were contacted regarding protected species and<br />

habitat impacts. Lincoln County, Ruidoso, and Ruidoso Downs were provided with information on the<br />

proposed project.<br />

Resource or Issue<br />

Geology<br />

Surface Water and Soils<br />

Commitment<br />

Rock or slope protection would be used to create a stabilized rock-cut face only if unstable rock is<br />

encountered. Rock would be excavated mechanically without the use <strong>of</strong> explosives. RSS wall<br />

with rock-filled baskets would be installed at the curves.<br />

Construction at Last <strong>Curve</strong> would neither involve modification to the existing drainage culvert or<br />

work within the Rio Ruidoso. Temporary fencing will be constructed around the wetlands at Last<br />

<strong>Curve</strong> to keep construction activities away from the wetlands. Under current design, Section 404<br />

permitting from the USACE and Section 401 permitting from the <strong>NM</strong>ED would not be necessary<br />

for construction activities at the three curves. The construction contractor and the <strong>NM</strong>DOT will<br />

obtain coverage under the NPDES permit for general construction activity regulated by the Clean<br />

Commitment<br />

Water Act. Construction activities will comply with all conditions <strong>of</strong> the Section 404 permit and<br />

Section 401 water quality certification. A copy <strong>of</strong> the SWPPP and Section 401 water quality<br />

certification will be kept at the project area during construction. The SWPPP will include best<br />

management practices (BMPs) to minimize soil erosion and sediment transport including<br />

mitigation measures to protect water quality. Temporary erosion and sediment control plans will<br />

be included in the plan sets. The construction contractor will also ensure that equipment does not<br />

leak oils or fuels into the wetlands or surface water. Fuels and hazardous materials will be stored<br />

away from wetlands and surface water.<br />

Construction activities will avoid wetlands at Last <strong>Curve</strong>. To prevent construction trucks and<br />

equipment from accidentally impacting wetlands, temporary fencing will be placed around<br />

wetlands that are located within 50 feet <strong>of</strong> the project area and are to be avoided.<br />

BMPs would be implemented to ensure protection <strong>of</strong> fish habitat water quality during and after<br />

construction. The U.S. Forest Service will be contacted prior to initiating any tree cutting. Any<br />

tree cutting or shrub clearing would occur outside <strong>of</strong> the migratory bird nesting season (March 1<br />

through August 30) or a biological survey for bird nests would be conducted prior to tree removal.<br />

If an occupied nest is found during this preconstruction survey, the nest will be avoided until the<br />

young birds have fledged.<br />

Construction at Texas Turn will be restricted between March 1 and August 30 to mitigate potential<br />

impacts to the Mexican spotted owl. However, if during Mexican spotted owl protocol surveys,<br />

the U.S. Forest Service Smokey Bear Ranger District determines that 1) nesting is not occurring, or<br />

2) the young have fully fledged, then construction could begin prior to August 30 if approved by<br />

the Smokey Bear Ranger District. The U.S. Forest Service does not need to be consulted after<br />

August 30 and prior to March 1 for construction activities at this curve.<br />

Construction at Last <strong>Curve</strong> will not occur between July 15 and September 30 to mitigate potential<br />

impacts to the Sacramento Mountain salamander. The <strong>NM</strong>DOT will coordinate with the U.S.<br />

Forest Service two weeks prior to commencement <strong>of</strong> construction to schedule a site visit and<br />

relocated individual Sacramento Mountain salamanders that could be impacted. Trees cut at Last<br />

<strong>Curve</strong> will be placed in salamander habitat through coordination with the U.S. Forest Service.<br />

The construction contractor will be responsible for managing hazardous substances in compliance<br />

with federal and state laws to ensure that no contamination occurs.<br />

<strong>NM</strong>DOT will develop a public information program for construction activities.<br />

Per <strong>NM</strong>DOT procedures, the construction contractor will be responsible for obtaining appropriate<br />

environmental clearances for materials pits and staging areas outside <strong>of</strong> the project area.<br />

Compliance specifications will be strictly administered for all equipment operations and dustproducing<br />

aspects <strong>of</strong> construction operations. Dust control mitigation measures are recommended<br />

during construction as specified in <strong>NM</strong>DOT Standard Specifications for Highway and Bridge<br />

Construction, 1017.14.5 Air Quality Requirements and Dust Abatement.<br />

Every reasonable effort will be taken to minimize construction noise through abatement measures<br />

such as work-hour controls and maintenance <strong>of</strong> muffler systems.<br />

Access to the Eagle Lakes campground, Lincoln National Forest, and Ski Apache will be<br />

maintained during construction except for brief intervals.<br />

All construction debris and waste will be removed from the construction zone as soon as it is<br />

practical and will be managed in accordance with federal and state regulations.<br />

To the extent practical, the construction contractor will recycle roadway materials for reuse on<br />

other roadway construction projects.<br />

RESPONSE BY EMAIL<br />

RE:<br />

<strong>NM</strong>DOT <strong>NM</strong> <strong>532</strong> <strong>Curve</strong>s <strong>Project</strong><br />

Dear Ms. Hyre:<br />

Your letter regarding the above named project was received in the <strong>New</strong> <strong>Mexico</strong> Environment<br />

<strong>Department</strong> (<strong>NM</strong>ED) and was sent to various Bureaus for review and comment. Comments were<br />

provided by the Air Quality, Surface Water Quality, and Ground Water Quality Bureaus, and are as<br />

follows.<br />

Air Quality Bureau<br />

The Air Quality Bureau has evaluated the information submitted with respect to the <strong>NM</strong>DOT <strong>NM</strong> <strong>532</strong><br />

<strong>Curve</strong>s <strong>Project</strong>, Lincoln County, <strong>New</strong> <strong>Mexico</strong>. Lincoln County is considered to be in attainment with all<br />

<strong>New</strong> <strong>Mexico</strong> and National Ambient Air Quality Standards.<br />

To further ensure air quality standards are met, applicable local or county regulations requiring noise<br />

and/or dust control must be followed; if none are in effect, controlling construction-related air quality<br />

impacts during projects should be considered to reduce the impact <strong>of</strong> fugitive dust and/or noise on<br />

community members.<br />

Potential exists for temporary increases in dust and emissions from earthmoving, construction<br />

equipment, and other vehicles; however the increases should not result in non-attainment <strong>of</strong> air quality<br />

standards. Dust control measures should be taken to minimize the release <strong>of</strong> particulates due to vehicular<br />

traffic and construction. Areas disturbed by the construction activities, within and adjacent to the project<br />

area should be reclaimed to avoid long-term problems with erosion and fugitive dust<br />

All asphalt, concrete, quarrying, crushing and screening facilities contracted in conjunction with the<br />

proposed project must have current and proper air quality permits. For more information on air quality<br />

permitting and modeling requirements, please refer to 20.2.72 <strong>NM</strong>AC.<br />

The project as proposed should have no long-term significant impacts to ambient air quality.


Surface Water Quality Bureau<br />

The U.S. Environmental Protection Agency (USEPA) requires National Pollutant Discharge Elimination<br />

System (NPDES) Construction General Permit (CGP) coverage for storm water discharges from<br />

construction projects (common plans <strong>of</strong> development) that will result in the disturbance (or redisturbance)<br />

<strong>of</strong> one or more acres, including expansions, <strong>of</strong> total land area. Because this project exceeds<br />

one acre (including staging areas, etc.), it may require appropriate NPDES permit coverage prior to<br />

beginning construction (small, one - five acre, construction projects may be able to qualify for a waiver<br />

in lieu <strong>of</strong> permit coverage - see Appendix C).<br />

Among other things, this permit requires that a Storm Water Pollution Prevention Plan (SWPPP) be<br />

prepared for the site and that appropriate Best Management Practices (BMPs) be installed and<br />

maintained both during and after construction to prevent, to the extent practicable, pollutants (primarily<br />

sediment, oil & grease and construction materials from construction sites) in storm water run<strong>of</strong>f from<br />

entering waters <strong>of</strong> the U.S. This permit also requires that permanent stabilization measures<br />

(revegetation, paving, etc.), and permanent storm water management measures (storm water<br />

detention/retention structures, velocity dissipation devices, etc.) be implemented post construction to<br />

minimize, in the long term, pollutants in storm water run<strong>of</strong>f from entering these waters. In addition,<br />

permittees must ensure that there is no increase in sediment yield and flow velocity from the<br />

construction site (both during and after construction) compared to pre-construction, undisturbed<br />

conditions (see Subpart 9.4.1.1)<br />

You should also be aware that EPA requires that all "operators" (see Appendix A) obtain NPDES permit<br />

coverage for construction projects. Generally, this means that at least two parties will require permit<br />

coverage. The owner/developer <strong>of</strong> this construction project who has operational control over project<br />

specifications, the general contractor who has day-to-day operational control <strong>of</strong> those activities at the<br />

site, which are necessary to ensure compliance with the storm water pollution plan and other permit<br />

conditions, and possibly other "operators" will require appropriate NPDES permit coverage for this<br />

project.<br />

The CGP was re-issued effective February 16, 2012. The CGP, Notice <strong>of</strong> Intent (NOI), Fact Sheet, and<br />

Federal Register notice can be downloaded at:<br />

Ground Water Quality Bureau<br />

<strong>New</strong> <strong>Mexico</strong> Environment <strong>Department</strong> (<strong>NM</strong>ED) Ground Water Quality Bureau (GWQB) staff reviewed the<br />

above-referenced letter as requested, focusing specifically on the potential effect to ground water resources<br />

in the area <strong>of</strong> the proposed project.<br />

The <strong>New</strong> <strong>Mexico</strong> <strong>Department</strong> <strong>of</strong> Transportation (<strong>NM</strong>DOT) and the Federal Highway Administration are<br />

proposing to reconstruct three curves on <strong>NM</strong> <strong>532</strong> in Lincoln County. <strong>NM</strong> <strong>532</strong> extends from <strong>NM</strong> 48 in Alto<br />

to the Ski Apache ski area. The work entails increasing the radii, correcting road grades and installation <strong>of</strong><br />

walls and guardrails.<br />

Please note that while implementation <strong>of</strong> the improvement project is not expected to adversely affect ground<br />

water, it will likely involve the use <strong>of</strong> heavy equipment, thereby leading to a possibility <strong>of</strong> contaminant<br />

releases (e.g., fuel, hydraulic fluid, etc.) associated with equipment malfunctions. The GWQB advises all


parties involved in the project to be aware <strong>of</strong> notification requirements for accidental discharges contained in<br />

20.6.2.1203 <strong>NM</strong>AC. Compliance with the notification and response requirements will further ensure the<br />

protection <strong>of</strong> ground water quality in the vicinity <strong>of</strong> the project.<br />

I hope this information is helpful to you.<br />

Sincerely,<br />

Morgan R. Nelson<br />

Environmental Impact Review Coordinator<br />
