50 CFR 13.23 - Amendment of permits.
(a)Permittee's request. Where circumstances have changed so that a permittee desires to have any condition of his permit modified, such permittee must submit a full written justification and supporting information in conformity with this part and the part under which the permit was issued.
(b) The Service reserves the right to amend any permit for just cause at any time during its term, upon written finding of necessity, provided that any such amendment of a permit issued under § 17.22(b) through (d) or § 17.32(b) through (d) of this subchapter shall be consistent with the requirements of § 17.22(b)(5), (c)(5) and (d)(5) or § 17.32(b)(5), (c)(5) and (d)(5) of this subchapter, respectively.
(c)Change of name or address. A permittee is not required to obtain a new permit if there is a change in the legal individual or business name, or in the mailing address of the permittee. A permittee is required to notify the issuing office within 10 calendar days of such change. This provision does not authorize any change in location of the conduct of the permitted activity when approval of the location is a qualifying condition of the permit.
