(1) The State of Maryland, or any agency or officer of the State, acting through the Attorney General;

(2) Any political subdivision of the State of Maryland, or any agency or officer of it acting on its behalf; and

However, an individual citizen either shall reside in the county or Baltimore City where the action is brought, or shall demonstrate that the alleged condition, activity, or failure complained of affects the environment where he resides.

(b) Any person given standing by subsection (a) of this section may bring and maintain an action for mandamus or equitable relief, including declaratory relief against any officer or agency of the State or political subdivision for failure on the part of the officer or agency of the State or political subdivision to perform a nondiscretionary ministerial duty imposed upon them under an environmental statute, ordinance, rule, regulation, or order, or for their failure to enforce an applicable environmental quality standard for the protection of the air, water, or other natural resources of the State, as expressed in a statute, ordinance, rule, regulation, or order of the State, or any political subdivision upon the request of the defendant, the court in its discretion may join as a party defendant any person against whom the plaintiff is requesting that governmental action be taken following notice to that person and if the court determines that the joinder would serve the interests of justice.
