On July 30, 2004, at 69 FR 45623, the FHWA published in the Federal Register a NPA proposing to amend the MUTCD to include methods to maintain traffic sign retroreflectivity. The NPA was issued in response to section 406 of the Department of Transportation and Related Agencies Appropriations Act, 1993 (Pub. L. 102-388; October 6, 1992). Section 406 of this Act directed the Secretary of Transportation to revise the MUTCD to include a standard for minimum levels of retroreflectivity that must be maintained for traffic signs and pavement markings, which apply to all roads open to public travel. The FHWA is currently conducting research to develop a standard for minimum levels of pavement marking retroreflectivity. The FHWA expects to initiate the pavement marking retroreflectivity rulemaking process once the research is concluded and the results are analyzed and considered.
The FHWA has led a significant effort toward establishing minimum-maintained levels of sign retroreflectivity since the statute was issued in 1993. Three national workshops were held in 1995 to educate State and local highway agency personnel and solicit their input regarding an initial set of minimum maintained sign retroreflectivity levels. In 1998, FHWA published revisions to initial research recommendations on minimum sign retroreflectivity levels  noting that additional work would be needed because the National Highway Traffic Safety Administration was also revising the Federal Motor Vehicle Safety Standard Number 108 Lamps, Reflective Devices, and Associated Equipment (FMVSS 108). The additional research was completed in 2003, at which time FHWA began preparing the NPA for traffic sign retroreflectivity for the MUTCD, which was published in 2004.
After considering and analyzing the comments on the NPA for minimum levels of retroreflectivity for traffic signs, FHWA decided to publish a supplemental notice of proposed amendments (SNPA). In particular, the SNPA was developed to address comments to the docket that: (1) Expressed concern that the NPA proposal did not meet the intent of the 1993 statute, (2) suggested that the table of minimum retroreflectivity levels should be placed in the MUTCD, (3) requested clarification of the compliance period, and (4) expressed concern about the resource requirements for complying with the rulemaking. The proposed MUTCD text in the SNPA included a STANDARD statement that required that a method be used to manage and maintain retroreflectivity and required that sign retroreflectivity be maintained at minimum levels. It also included the table of minimum retroreflectivity levels in the MUTCD. These changes were significant enough to warrant an SNPA to allow FHWA to obtain and assess additional public comments. The SNPA was published on May 8, 2006, at 71 FR 26711. The comment period for the SNPA ended on November 6, 2006.
Based on the comments received and its own experience, FHWA is issuing this final rule establishing the minimum levels of retroreflectivity that must be maintained for traffic signs. The FHWA is designating the MUTCD, with these changes incorporated, as Revision 2 of the 2003 Edition of the MUTCD.
The text of this Revision No. 2 and the text of the 2003 Edition of the MUTCD with Revision No. 2 final text incorporated are available for inspection and copying as prescribed in 49 CFR Start Printed Page 72575part 7 at the FHWA Office of Transportation Operations. Furthermore, final Revision No. 2 changes are available on the official MUTCD Web site at http://mutcd.fhwa.dot.gov. The entire MUTCD text with final Revision No. 2 text incorporated is also available on this Web site.
Summary of Comments
The FHWA received 121 letters submitted to the docket in response to the SNPA containing approximately 550 individual comments. The FHWA received comments from the National Committee on Uniform Traffic Control Devices (NCUTCD), the American Association of State Highway and Transportation Officials (AASHTO) and 20 State Departments of Transportation (DOT) members of AASHTO, the National Association of County Engineers (NACE) and seven county association members of NACE, city and county governmental agencies, consulting firms, private industry, associations, other organizations, and individual private citizens. The FHWA has considered all these comments. Docket comments and summaries of FHWA's analyses and determinations are discussed below. General comments are discussed first, followed by discussion of major issues and adopted changes, and finally, discussion of other comments.
Discussion of General Comments
Many respondents agreed with the intent and the concepts proposed in both the NPA and the SNPA. In analyzing the comments to the SNPA, FHWA decided that additional clarification should be provided in the MUTCD text and in the explanations provided in the final rule in order to address the following five major issues:
(1) Clarification of compliance period;
(2) Resource burdens on public agencies;
(3) Statutory requirements;
(4) Table of minimum retroreflectivity levels in the MUTCD; and
(5) Impacts of sign retroreflectivity on safety.
Discussion of Major Issues
This section provides a discussion of each of the five major issues raised by commenters in response to the SNPA, along with FHWA's analysis and resolution.
(1) Clarification of the compliance period.
Several county associations and many county and local officials requested an extension from 2 to 4 years for the compliance period for the establishment and implementation of a method to maintain sign retroreflectivity, in order to accommodate their programs within their 2-year budget cycles. There were also a few requests to extend the 7 and 10 year compliance periods for the signs themselves.
Considering the comments regarding budget cycles, particularly budget cycles for local agencies, FHWA has extended to 4 years the compliance period for establishing and implementing a sign assessment or management method to maintain minimum levels of sign retroreflectivity. This extended compliance period will allow transportation agencies to make allowances for budgets (including working with the States or regional organizations) to access funds and/or partnerships to achieve the minimum levels of sign retroreflectivity.
The 7 and 10 year compliance dates for minimum levels for sign retroreflectivity will remain 7 years for regulatory, warning, and ground-mounted guide signs and 10 years for street name and overhead guide signs, because these compliance target dates correspond to the normal expected service life of sign sheeting and will allow highway agencies to make the proper accommodations in their efforts to maintain minimum retroreflectivity levels. The 7 and 10 year compliance dates are counted from the effective date of this rule and are not in addition to the 4-year period for establishing the methods.
(2) Resource burdens on public agencies.
While the Minnesota DOT (MNDOT) recognized that the proposed language would impose additional time and resource burdens on public agencies, it did not perceive this rule as an “unmanageable burden.” Several sign manufacturers and some private citizens appreciated the FHWA's effort to point out that Federal funds are available for up to 100 percent funding of “replacement of signs in this program.” In addition, the American Traffic Safety Services Association (ATSSA), the American Automobile Association (AAA), the American Association of Retired People (AARP), the American Highway Users Alliance (AHUA), and several private citizens agree that the benefits from this rulemaking will outweigh the costs that agencies may experience. However, AASHTO, NACE, and several State and local DOTs believe that the requirements, as proposed in the SNPA, are an unfunded mandate with serious financial implications to their agencies.
The FHWA conducted a study to determine if unfunded mandates, as defined by the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4, 109 Stat. 48, March 22, 1995), would be imposed by including requirements in the MUTCD for minimum maintained traffic sign retroreflectivity levels. Based on the analysis, this rulemaking effort does not impose an unfunded mandate. Additionally, because Federal-aid highway dollars are often provided to States to use for these types of sign replacements, this requirement does not rise to the level of an unfunded mandate.
One commenter reviewed the FHWA's report “Maintaining Traffic Sign Retroreflectivity: Impacts on State and Local Agencies (DRAFT)” (1994—15149-06), and suggested that perhaps there was a mathematical error in that report that would mean that the costs incurred by agencies when replacing signs would be above those that can be required from agencies without funding. The FHWA has updated the 1994 draft report with a 2007 version (see footnote # 2). The updated report now includes the costs of overhead and street name signs, which the 1994 version excluded. The updated report concludes that the national impact of including the minimum maintained traffic sign retroreflectivity levels in the MUTCD is approximately $37.5 million over a 10-year implementation period, with a maximum annual impact of $4.5 million in years 1 through 7. This is below the annual $128.1 million unfunded mandate level.
The FHWA has also provided ample phase-in time for agencies to comply. Agencies are already required to have a highway safety program that includes provisions for the upgrading of substandard traffic control devices and installations to achieve conformity with the MUTCD, so this rulemaking does not create additional burdens.
While many counties believe that FHWA should consider a funding stream directly to local jurisdictions for rulemaking activities such as minimum retroreflectivity standards, such funding stream discussions are outside the scope of this rulemaking. Signing programs remain eligible for Federal-aid highway dollars.
(3) Statutory requirements:
Several organizations representing highway users from a safety perspective agree that the language proposed in the SNPA satisfied the statutory requirements to establish a standard for the minimum levels of sign Start Printed Page 72576retroreflectivity; however, AASHTO, and several States, commented that Congress did not explicitly indicate that the minimum values for maintaining sign retroreflectivity had to be included in the MUTCD as a Standard. Alternatively, the Advocates for Highway and Auto Safety (AHAS) believe that the language proposed in the SNPA still did not fully satisfy the statutory requirements, which AHAS interprets as requiring the establishment of specific and mandatory minimum levels of retroreflectivity for signs and pavement markings in the MUTCD and an obligation on State and local authorities to maintain those specific minimum values of retroreflectivity. AHAS stated that the intent can only be met by including such requirements in a “standard” statement in the MUTCD, which is defined as one of the “required, mandatory, or specifically prohibitive practice regarding a traffic control device.”
The FHWA includes the reference to minimum levels for sign retroreflectivity in a Standard statement because the statute requires the Secretary to revise the MUTCD to include a standard for minimum levels of retroreflectivity that must be maintained for traffic signs. Under the MUTCD's current organization, the best way to do this is by including it in a STANDARD statement, because Standards represent requirements. In addition, the congressional reference to a standard did not exclude the use of GUIDANCE, OPTION, and SUPPORT statements to help clarify the STANDARD statement of required minimum levels of retroreflectivity that must be maintained, similar to the other sections of the MUTCD.
The FHWA also received comments from the city of Plano, Texas, and the Illinois County Engineers expressing a concern and/or confusion that the language proposed in the SNPA “imbedded” a GUIDANCE statement within a STANDARD, because the STANDARD statement referenced the GUIDANCE statement for minimum retroreflectivity levels.
Based on this concern, and to clarify FHWA's intent, FHWA revises the STANDARD statement to explicitly reference Table 2A-3 Minimum Maintained Retroreflectivity Levels, which contains minimum-maintained retroreflectivity levels for various sign color combinations and types of sign sheeting.
The National Association of Counties (NACo) and NACE suggested adding “recommended” before “minimum level” in describing the retroreflectivity levels shown in Table 2A-3. The FHWA retains the wording “minimum level” in describing the levels shown in Table 2A-3, because the word “recommended” is not appropriate when referencing a Standard.
(4) Table of minimum retroreflectivity levels in the MUTCD.
The ATSSA, AAA, AARP, AHUA, Minnesota and Virginia DOTs, the city of Plano, Texas, sign manufacturers, and many private citizens were in favor of including the table of minimum retroreflectivity levels in the MUTCD. However, many organizations, such as AASHTO, NACo, NACE, and numerous State DOTs, as well as county and local agencies were opposed to the inclusion of the table. Those who opposed including the table in the MUTCD expressed concern over potential litigation that could be brought against public agencies if an individual sign within their jurisdiction was to fall below the minimum maintained levels in the table. The NCUTCD also commented that before any table is inserted into the MUTCD, FHWA should provide substantial clarification regarding the process and frequency for updating or changing the table of retroreflectivity values.
The FHWA believes that including this table in the MUTCD is necessary to satisfy the statutory requirement that the MUTCD be amended to include minimum retroreflectivity levels. Therefore, the FHWA includes Table 2A-3, titled “Minimum Maintained Retroreflectivity Levels” in the MUTCD. The FHWA also believes inclusion of the table will provide clarity and convenience to the users of the MUTCD. In response to the request by the NCUTCD that FHWA clarify the process for updating or changing values in the table, we note that updates or changes to the table would be subject to a public rulemaking process before FHWA could adopt changes to the values of the table in the MUTCD. This process will include notice and opportunity for comment by the public.
Table 2A-3 will be included in the MUTCD as follows (note that the values in this table have not changed during the rulemaking process):Start Printed Page 72577 Start Printed Page 72578
The FHWA received comments from NACo, NACE and several local agencies that suggested adding a statement clarifying that all signs need not meet the minimum retroreflectivity values at every point in time.
Considering these comments in conjunction with FHWA's understanding that there will be cases where vandalism, weather, or damage due to a crash influences the visibility of a sign, the FHWA clarified the SUPPORT statement in Section 2A.09. The revised statement clarifies that an agency or an official having jurisdiction would be in compliance with the Standard even if there are some individual signs that do not meet the minimum retroreflectivity levels at a particular point in time, provided that an assessment or management method implemented in accordance with Section 2A.09 of the MUTCD is being used.
The FHWA also received comments from NACo, NACE and several local agencies stating specific concerns that the establishment of specific retroreflectivity values within Table 2A-3 will become “the de-facto standard” that will be used against highway agencies in tort claims and lawsuits.
The FHWA believes that the selection of a reasonable method for maintaining sign retroreflectivity and strict adherence to the same might serve to defend highway agencies in tort liability claims and litigation. Public agencies and officials that implement and follow a reasonable method in conformance with the national MUTCD would appear to be in a better position to successfully defend tort litigation involving claims of improper sign retroreflectivity than jurisdictions that lack any method. In addition, as a result of adding clarifying language to the Support statement indicating that once an assessment or management method is used by an agency or official having jurisdiction, agencies would be in compliance with the STANDARD even if some individual signs do not meet the minimum retroreflectivity levels at a point in time.
Including Table 2A-3 in the MUTCD does not imply that an agency needs to measure the retroreflectivity of every sign in its jurisdiction. Instead, agencies must implement methods designed to provide options on how to maintain the minimum retroreflectivity levels, using the criteria in Table 2A-3.
(5) Impacts of sign retroreflectivity on safety.
The ATSSA and several sign manufacturers believe there is a proven link between maintained sign retroreflectivity and safety, especially as it relates to older drivers. In addition, several citizens believe that improved retroreflectivity will lead to safer roads. One citizen who worked for several years in the field of nighttime visibility stated that his research with actual drivers on the road showed conclusive results that greater levels of retroreflectivity increase a driver's ability to be warned well in advance of a traffic situation or pedestrian encounter. The North Carolina DOT (NCDOT) and the AHAS, however, recommend that further FHWA studies be done to demonstrate that retroreflective improvements translate into safety improvements.
The FHWA believes that improving sign retroreflectivity will be a benefit to all drivers, including older drivers. All drivers need legible signs in order to make important decisions at key locations, such as intersections and exit ramps on high speed facilities. This is particularly true for regulatory and warning signs. This is fundamental to safe driving, and the lack of uniform retroreflectivity standards has led to wide variations in maintenance levels of these critical signs. As discussed in the SNPA, there have been some investigations that demonstrate potential safety benefits of upgrading sign materials. More importantly, maintaining sign retroreflectivity is consistent with one of FHWA's primary goals, which is to improve safety on the Nation's streets and highways. Improvements in sign visibility will also support FHWA's efforts to be responsive to the needs of older drivers, which is important because the number of older drivers is expected to increase significantly in the next 30 years.
Discussion of Other Comments
In addition to the five major issues discussed in the previous section, FHWA also received comments that can be grouped into the following three topics:
(6) Assessment methods;
(7) Blue and brown signs; and
(8) Minimum retroreflectivity levels.
This section contains a discussion of each of these topics.
(6) Assessment methods:
The FHWA received comments from the AASHTO, NCUTCD, ATSSA, AHAS, AAA, AARP, AHUA, ARTBA, Maryland and Wisconsin DOTs, and several counties in Illinois regarding the assessment and management methods for maintaining sign retroreflectivity as proposed in the GUIDANCE statement of the SNPA. The AASHTO and several State DOTs did not support actual measurement of signs as one of the methods, but supported visual nighttime inspections, blanket replacement, control signs, and expected sign life methods.
The city of Plano, Texas and a private citizen suggested that the numerical values in Table 2A-3 should only apply to Method B: Measured Sign Retroreflectivity. Those commenters suggested that for all other methods where subjective judgment is used, such as visual nighttime inspection, the table should serve as guidance for local offices to reject and accept signs.
Finally, the NCUTCD, the Illinois Association of County Engineers, and the DeWitt County, Illinois Highway Department suggested adding additional language to the GUIDANCE statement to explicitly, rather than implicitly, state that other assessment methods based on engineering study can be used to assess sign retroreflectivity.
The FHWA believes that the final rule provides several assessment or management methods that agencies can choose from, based on the method that best fits the agencies' resources and needs. An agency can choose to use either assessment methods or management methods, or a combination; however, agencies should develop a method in such a way that it corresponds to the values in Table 2A-3. The methods have been developed to provide flexibility for agencies for addressing their local conditions. To address the comments received regarding the types of assessment methods that should be used, FHWA clarifies the GUIDANCE statement by adding a sixth method to the list of assessment or management methods titled “Other Methods,” which explicitly states that other methods developed based on engineering studies can be used.
(7) Blue and brown signs:
In the SNPA, FHWA asked for comments on the need for retroreflectivity levels to be developed for signs with blue and brown Start Printed Page 72579backgrounds. The Maryland State Highway Administration suggested that recommended minimum retroreflectivity levels be established for blue-background signs and that those levels apply to certain signs such as Hospital, EMS, Ambulance Station, and Emergency Medical Care signs, whose nighttime readability can be important. The combined letter from a representative of AAA, AARP, and AHUA, and one comment letter from a sign manufacturer stated that blue and brown signs are intended for use both day and night, and that motorist safety, particularly for older drivers, would be enhanced by including minimum retroreflectivity levels for blue and brown signs. The commenters acknowledged that if blue and brown signs are being excluded because there is a lack of data on which to base a requirement, a “placeholder” could be included in the MUTCD until more data is available and the table of minimum levels can be updated.
The FHWA is currently studying blue and brown minimum sign retroreflectivity levels. Because the study has not been finalized and FHWA did not analyze the costs associated with the sign retroreflectivity of blue and brown signs in the economic impacts study, minimum retroreflectivity levels for blue and brown signs are not included in the MUTCD at this time. At the conclusion of FHWA's study on this topic, the results may indicate a need to pursue such a requirement. If so, updates or changes to Table 2A-3 would be subject to the public rulemaking process before FHWA could add blue and brown minimum retroreflectivity levels.
(8) Minimum retroreflectivity levels:
Several of the commenters, including AASHTO, NACE, the Illinois and Indiana Associations of County Engineers, DeWitt County, Illinois Highway Department, the North Carolina DOT and the Maryland State Highway Administration suggested that the data within the table were not precise, and reflected data that were developed based on assumptions and varying characteristics.
The FHWA acknowledges that the data are based on some assumptions and varying characteristics; however, they are based on the latest science and empirical-based research emphasizing older drivers. The supporting research reflects the best information at this time. One of the key aspects to the research supporting the minimum retroreflectivity levels is that it was based on field studies under conditions on a closed course facility that represented real roadway scenarios to the maximum extent possible without jeopardizing safety. Research subjects were recruited and participated in the research, which ultimately developed cumulative distribution profiles for luminance levels needed to accommodate the legibility of older drivers. These luminance levels were then used in conjunction with computer modeling to determine the retroreflectivity needed under a variety of roadway conditions. The computer modeling allows analyses of an infinite set of roadway scenarios, but is based on the luminance levels derived through the human factors research supported by FHWA.
After the research was completed, FHWA held national workshops, which included nighttime inspections of signs at various retroreflectivity levels. The participants of the workshops evaluated the signs at night using a visual inspection technique. The results of this effort helped confirm that the minimum retroreflectivity levels in Table 2A-3 are appropriate.
The NCDOT suggested that a tiered system be applied to the retroreflectivity levels, similar to the tiered system used for letter heights and sign sizes based on roadway classification. The NCDOT commented that retroreflective sign applications for lower speed, lower volume roads should be coordinated with lower retroreflectivity values.
The FHWA believes that the values shown in the table are applicable to all classifications of roads, including lower volume and slower speed roadways. The retroreflectivity levels are based on the legibility design threshold level as specified in Section 2A.14 of the MUTCD (40 feet of legibility per inch of letter height). Therefore, the size of the sign, and the message on the sign, play a key role in the retroreflectivity levels. Smaller signs have smaller messages, which mean drivers need to be closer to the signs to read them. As the distance between the sign and the vehicle decreases, the efficiency of retroreflectivity materials generally decreases, meaning that more retroreflectivity is needed. This often outweighs the increased illumination available from the vehicle headlamps. The minimum retroreflectivity levels were designed to be easy to implement, without added complexities such as a tiered system based on letter heights and sign sizes. However, with the proper support (i.e., an engineering study), and using the values in Table 2A-3 as minimum maintained retroreflectivity levels, there is flexibility in this final rule and the associated MUTCD language that allows for an agency to develop a more complex set of minimum retroreflectivity levels, if it chooses to do so. Such levels cannot be below the minimums in Table 2A-3.
As mentioned in item 3 under Major Issues, a few commenters such as NACE, the NCUTCD and others, believed that Table 2A-3 and its title should be referred to as “Recommended.” The FHWA believes that it is inappropriate to include “Recommended” in the title of a table that is referenced in a STANDARD statement of the MUTCD. In addition, the word “Recommended” implies guidance, rather than a standard, and would therefore be confusing.
ATSSA, the AHAS and the MNDOT agreed with eliminating Type I material for ground-mounted signs, and they also agreed with eliminating Types I, II, and III for overhead guide sign legends. These commenters felt that prohibiting the use of these less efficient retroreflective materials would substantially improve the nighttime driving environments, especially for older drivers with a variety of visual impairments. ATSSA also supported including Type X materials so that all currently defined American Society of Testing Materials (ASTM) Type designations that are used for traffic signs will be included in the MUTCD.
The NCDOT disagrees with any retroreflective requirement for illuminated signs. Their reasoning is that the assessment and management methods used to maintain retroreflectivity do not address signs with illumination and that Section 2A.08 does not require retroreflectivity for illuminated signs.
Illuminated signs do need to meet the minimum retroreflectivity requirements because there are times that the signs may not be illuminated due to power failure. Previous research has shown that overhead signs can be effective Start Printed Page 72580without lighting, as long as the appropriate retroreflective sheeting materials are used to fabricate the sign. With this knowledge, many agencies have elected to use more efficient retroreflective sheeting on overhead guide signs without sign lighting, citing adequate visibility and concerns about energy use and light pollution (although sign lighting may continue to be used in areas of complex surroundings and/or roadway geometries). The minimum retroreflectivity levels in Table 2A-3 in the MUTCD prohibit the use of less efficient reflective materials for overhead signs so that agencies do not use them. As a result, agencies are more likely to select appropriate materials to meet nighttime driving requirements.
One supplier of overhead sign lighting systems and 22 citizens suggested that lighting of overhead signs should be mandatory. This final rule does not change the existing MUTCD language recommending lighting for overhead signs. Mandating lighting for overhead signs is outside the scope of this rulemaking.
One sign manufacturer suggested that retroreflectivity levels measured at 0.5 degree observation angle be included. As discussed in item #12 of the SNPA, research has been completed that supports moving toward the 0.5-degree concept and the ASTM has started working toward a revision to its specifications to describe 0.5-degree measurements. The FHWA believes that it is not practical to implement minimum retroreflectivity levels based on an observation angle of 0.5 degrees until measuring devices become more readily available, and the ASTM completes its work developing a standard measurement specification. At that time there may be a need for an alternative table and a transition period established while the 0.2-degree measurement geometries and devices are phased out. If so, these changes will be introduced through public rulemaking procedures described earlier for MUTCD changes or additions.
To address the comments to the docket, the FHWA adopts the following key changes to Section 2A.09 Maintaining Minimum Retroreflectivity in the MUTCD from what was proposed in the SNPA:
(A) In the STANDARD statement, a reference to Table 2A-3 was added to clarify that the levels contained in Table 2A-3 are the minimum levels that are to be used by public agencies or officials having jurisdiction when they develop an assessment or management method that is designed to maintain sign retroreflectivity.
(B) The 2nd SUPPORT statement was clarified to indicate that once an assessment or management method is used, an agency or official having jurisdiction would be in compliance with the STANDARD even if some individual signs do not meet the minimum retroreflectivity levels at a particular point in time.
(C) The GUIDANCE statement was modified by adding a sixth method to the list of assessment or management methods that should be used to maintain sign retroreflectivity titled “Other Methods,” which explicitly states that other methods developed based on engineering studies can be used.
In addition, FHWA adopts a 4-year compliance date (instead of the proposed 2-year compliance date) for implementation and continued use of an assessment or management method that is designed to maintain traffic sign retroreflectivity at or above the established minimum levels.
The final rule meets statutory requirements, provides clarity where needed, and provides flexibility for compliance.
Rulemaking Analyses and Notices
Executive Order 12866 (Regulatory Planning and Review) and U.S. DOT Regulatory Policies and Procedures
The FHWA has determined that this action is not a significant regulatory action within the meaning of Executive Order 12866 or under the regulatory policies and procedures of the U.S. Department of Transportation. While the FHWA had preliminarily designated this rulemaking as significant during the NPRM and SNPRM stages, the FHWA has determined that this rulemaking does not meet the criteria for a “significant regulatory action” under Executive Order 12866. This rule will not adversely affect, in a material way, any sector of the economy. Additionally, this rulemaking will not interfere with any action taken or planned by another agency and will not materially alter the budgetary impact of any entitlements, grants, user fees or loan programs.
It is anticipated that the economic impact of this rulemaking would cause minimal additional expenses to public agencies. In 2007, FHWA updated its analysis of the cost impacts to State and local agencies to reflect higher material costs due to inflation, an increase in the proportion of signs that would be replaced with higher-level sign sheeting material, and changes in the overall mileage of State and local roads. The findings of the 2007 analysis show that the costs of the proposed action to State and local agencies would be less than $128.1 million per year. The 7-year implementation period for ground-mounted signs will allow State and local agencies to delay replacement of recently installed Type I signs until they have reached their commonly accepted 7-year service life. The 10-year compliance period for overhead signs would allow an extended period of time because of the longer service life typically used for those signs. The final rule does not affect the impacts assessments described above.
Currently, the MUTCD requires that traffic signs be illuminated or retroreflective to enhance nighttime visibility. In 1993, Congress mandated that the MUTCD contain standards for maintaining minimum traffic sign and pavement marking retroreflectivity. The final rule provides additional guidance, clarification, and flexibility in maintaining traffic sign retroreflectivity that is already required by the MUTCD. The minimum retroreflectivity levels and maintenance methods consider changes in the composition of the vehicle population, vehicle headlamp design, and the demographics of drivers. The FHWA expects that the levels and maintenance methods will help to promote safety and mobility on the Nation's streets and highways.
This rulemaking addresses comments received in response to the Office of Management and Budget's (OMB's) request for regulatory reform nominations from the public. The OMB is required to submit an annual report to Congress on the costs and benefits of Federal regulations. The 2002 report included recommendations for Start Printed Page 72581regulatory reform that OMB requested from the public. One recommendation was that the FHWA should establish standards for minimum levels of brightness of traffic signs. The FHWA has identified this rulemaking as responsive to that recommendation.
Regulatory Flexibility Act
In compliance with the Regulatory Flexibility Act (Pub. L. 96-354, 5 U.S.C. 601-612), the FHWA has evaluated the effects of this final rule on small entities and has determined that this final rule will not have a significant economic impact on a substantial number of small entities.
This rule would apply to State Departments of Transportation in the execution of their highway programs, specifically with respect to the retroreflectivity of traffic signs. Additionally, sign replacement is often eligible for up to 100 percent Federal-aid funding—this applies to local jurisdictions and tribal governments, pursuant to 23 U.S.C. 120(c). The implementation of this final rule would not affect the economic viability or sustenance of small entities, as States are not included in the definition of a small entity that is set forth in 5 U.S.C. 601.
Unfunded Mandates Reform Act of 1995
This rule does not impose unfunded mandates as defined by the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4, 109 Stat. 48, March 22, 1995). The impacts analysis shows that State and local agencies would be likely to incur impacts of roughly $37.5 million. Using a 7-year implementation period for regulatory, warning, and guide signs and a 10-year implementation period for street name and overhead guide signs, the annual impacts are estimated to be approximately $4.5 million for years 1 through 7, and $2.1 million for years 8 through 10. The estimates are based upon the added cost of more efficient performance sign materials. The labor, equipment, and mileage costs for sign replacement were excluded under the assumption that the proposed implementation period was long enough to allow replacement of non-compliant signs under currently planned maintenance cycles. Therefore, this final rule will not result in the expenditure by State, local, and tribal governments, in the aggregate, or by the private sector, of $128.1 million or more in any one year. In addition, sign replacement is often eligible for up to 100 percent Federal-aid funding—this applies to local jurisdictions and tribal governments, pursuant to 23 U.S.C. 120(c). Further, the definition of “Federal Mandate” in the Unfunded Mandates Reform Act excludes financial assistance of the type in which State, local or tribal governments have authority to adjust their participation in the program in accordance with changes made in the program by the Federal Government. The Federal-aid highway program permits this type of flexibility.
Executive Order 13132 (Federalism)
The FHWA analyzed this final rule in accordance with the principles and criteria contained in Executive Order 13132, dated August 4, 1999, and FHWA has determined that this final rule will not have a substantial direct effect or sufficient federalism implications on States and local governments that would limit the policy-making discretion of the States and local governments. Nothing in the MUTCD directly preempts any State law or regulation.
The MUTCD is incorporated by reference in 23 CFR Part 655, subpart F. This final rule is in keeping with the Secretary of Transportation's authority under 23 U.S.C. 109(d), 315, and 402(a) to promulgate uniform guidelines to promote the safe and efficient use of the Nation's streets and highways.
Executive Order 13175 (Tribal Consultation)
The FHWA has analyzed this action under Executive Order 13175, dated November 6, 2000, and believes that it will not have substantial direct effects on one or more Indian tribes, will not impose substantial direct compliance costs on Indian tribal governments, and will not preempt tribal law. Therefore, a tribal summary impact statement is not required.
Executive Order 13211 (Energy Effects)
The FHWA has analyzed this final rule under Executive Order 13211, Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use. The FHWA has determined that this is not a significant energy action under that order because, although it is a significant regulatory action under Executive Order 12866, it is not likely to have a significant adverse effect on the supply, distribution, or use of energy. Therefore, a Statement of Energy Effects under Executive Order 13211 is not required.
Executive Order 12372 (Intergovernmental Review)
Catalog of Federal Domestic Assistance Program Number 20.205, Highway Planning and Construction. The regulations implementing Executive Order 12372 regarding intergovernmental consultation on Federal programs and activities apply to this program.
Paperwork Reduction Act
Under the Paperwork Reduction Act of 1995 (PRA) (44 U.S.C. 3501, et seq.), Federal agencies must obtain approval from OMB for each collection of information they conduct, sponsor, or require through regulations. The FHWA has determined that this action does not contain a collection of information requirement for the purposes of the PRA.
Executive Order 12988 (Civil Justice Reform)
This action meets applicable standards in Sections 3(a) and 3(b)(2) of Executive Order 12988, Civil Justice Reform, to minimize litigation, to eliminate ambiguity, and to reduce burden.
Executive Order 13045 (Protection of Children)
The FHWA has analyzed this action under Executive Order 13045, Protection of Children from Environmental Health Risks and Safety Risks. This is not an economically significant action and does not concern an environmental risk to health or safety that might disproportionately affect children.
Executive Order 12630 (Taking of Private Property)
This action would not affect a taking of private property or otherwise have taking implications under Executive Order 12630, Governmental Actions and Interference with Constitutionally Protected Property Rights.
National Environmental Policy Act
The agency has analyzed this final rule for the purpose of the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.) and has determined that it will not have any effect on the quality of the environment.
