This excerpt taken from the MYRG 10-K filed Mar 12, 2009.
While we are not regulated as a public utility, our operations are subject to various federal, state and local laws and regulations including:
In addition, we conduct a portion of our business in the southwestern United States, where we run a more significant risk of disturbing Native American artifacts and archeological sites. If we encounter artifacts on a site on one of our construction projects, we may need to halt operation while construction is moved or steps are taken to comply with local law and the Archaeological Resources Protection Act of 1979 ("ARPA"). In addition, under ARPA we may be subject to fines or criminal sanctions if we disturb or damage protected sites.
We believe that we are in material compliance with applicable regulatory requirements and have all material licenses required to conduct our operations. Our failure to comply with applicable regulations could result in substantial fines and/or revocation of our operating licenses. Many state and local regulations governing electrical construction require permits and licenses to be held by individuals who typically have passed an examination or met other requirements.
