facts, we do not recount them here. We have jurisdiction under 28 U.S.C. § 1291,

and we affirm.

Having filed a complaint alleging retaliation in violation of the “complaints

clause” of the Surface Transportation Assistance Act (“STAA”), 49 U.S.C.

§ 31105(a)(1)(A), Evans was required to show that he engaged in a statutorily-

protected activity. Id. § 42121(b)(2)(B)(i).1 This portion of the STAA protects

employees who have “filed a complaint or begun a proceeding related to a

violation of a commercial motor vehicle safety or security regulation, standard or

order.” Id. § 31105(a)(1)(A)(i).

Evans argues that his complaints to the Occupational Safety and Health

Administration and Reddaway management about poor conditions at two terminal

lots on his trucking route were related to several Federal Motor Carrier Safety

Regulations that govern the commercial trucking industry. Specifically, Evans

points to regulations of driving in extreme weather and road conditions (49 C.F.R.

1 Because the STAA was amended in 2007 to incorporate the burdens of proof in the whistleblower provision of the Wendell H. Ford Aviation Investment and Reform Act for the 21st Century (“AIR-21”), we apply the AIR-21 burden- shifting framework. See 49 U.S.C. § 31105(b)(1) (“All complaints initiated under this section shall be governed by the legal burdens of proof set forth in section 42121(b).”); cf. Van Asdale v. Int’l Game Tech., 577 F.3d 989, 996 (9th Cir. 2009) (applying AIR-21 burden-shifting framework to retaliation claim under the Sarbanes-Oxley Act).

2 § 392.14), driving while the operator’s alertness is impaired by “fatigue, illness, or

another other cause” (49 C.F.R. § 392.3), and conducting mandatory vehicle safety

inspections (49 C.F.R. §§ 392.7, 392.9).

Evans’ complaints—dirt, dust, gravel, ruts, poor lighting, and lack of

fencing/security at the two Reddaway terminals—relate to general workplace

safety conditions at the lots, rather than commercial motor vehicle safety or

security. Thus, his complaints are not reasonably related to a violation of a

commercial motor vehicle safety regulation and are therefore not protected activity

under the STAA.

AFFIRMED.
