*493 OPINION
The issue presented is whether the Department of Transportation may seek to enjoin the operation of an unlicensed airport where this is not specifically authorized by the controlling statute.
Appellee Troy Beam (“Beam”) used a portion of his property in Hopewell Township, Cumberland County, to take off in, land, and house his private airplane. In 1999, the state Department of Transportation (the “Department”) filed a complaint in equity and petition for a preliminary injunction, alleging that Beam was operating an airport without a license in violation of Section 471.3 of Title 67 of the Pennsylvania Code, 67 Pa.Code § 471.3, and after refusing the Department’s invitation to apply for a license. 1 In response, Beam denied that he maintained or operated an airport and asserted further that the Department lacked the authority to seek an injunction against him.
Following a hearing, the common pleas court denied the request for preliminary injunction and, on Beam’s motion, granted summary judgment in his favor and dismissed the Department’s complaint. The Department appealed, and the Commonwealth Court affirmed.
See Commonwealth, Dep’t of Transp. v. Beam,
Presently, the Department argues that the reviewing courts construed too narrowly the authority conferred upon it by the Legislature, as they failed»to acknowledge that a statutory grant of authority consists not only of that which is expressly granted, but also of authority which is necessarily implied. One such aspect of implied authority, the Department asserts, is the capacity to institute judicial proceedings where necessary to the execution of its statutory responsibilities. The Department also maintains that a violation of the law is tantamount to a public nuisance, which is enjoinable at common law regardless of whether such an injunction is statutorily authorized. Beam contends that, to the contrary, the courts cannot ignore the Legislature’s omission of a mechanism for enforcing the prohibition against operation of an unlicensed airport from the Aviation Code. As the General Assembly has elected to provide such mechanisms in other statutes and in *495 other provisions ol‘ the Aviation Code, Beam argues, it must be presumed that the omission at issue was intentional; 4 thus, it would be an inapftropriate expansion of the courts’ equitable jurisdiction to seek to remedy that omission. Nor, in Beam’s view, is his airport enjoinable as a public nuisance, as it poses no danger to the public. 5
This Court has long adhered to the precept that the power and authority exercised by administrative agencies must be conferred by legislative language that is clear and unmistakable.
See United Artists’ Theater Circuit, Inc. v. City of Phila.,
As noted, the Aviation Code contains the core authorization for the Department’s regulation of airport operations. Section 5301(a) defines the Department’s general aviation-related powers in pertinent part as follows:
(a) General powers. — The department shall administer the provisions of this part [Part. Ill (Aviation) of Title 74 (Transportation) ] and, for that purpose, shall promulgate and enforce regulations as necessary to execute the powers vested in it by this part and other laws relating to aviation, airports and air safety within this Commonwealth. The secretary shall have the powers and perform the functions provided by this part.
74 Pa.C.S. § 5301(a). Section 5301(b) grants to the Department certain powers, the first of which is to “[pjrovide for the examination, rating and licensing of airports.” 74 Pa.C.S. *497 § 5301(b)(1). Section 5301(e) specifies several limitations, including the requirement that any license for an airport shall be effective for a period of not less than two years, with the proviso that the Department may revoke such a license upon proof of any violation of aviation-related laws or regulations. See 74 Pa.C.S. § 5301(e)(2). 7 Section 6103(a) authorizes the Department to establish fees for aviation services, including, inter alia, the issuance of private airport licenses. See 74 Pa.C.S. § 6103(a)(3). As the Commonwealth Court and the common pleas court observed, these provisions, representing the sum total of the General Assembly’s directives to the Department regarding the licensing of airports, do not specifically authorize the Department to seek, or preclude it from seeking, injunctive relief against the operation of an unlicensed airport. 8
Nevertheless, it is evident from the Aviation Code that the Legislature intended to confer upon the Department an ability
*498
to secure compliance with the statutory requirements.
9
Indeed, such conclusion not only flows from the statutory framework but is bolstered by the character of the enactment, which involves the substantial public safety and welfare implications of aircraft and airport operations.
Cf. City of Columbia v. Board of Health and Envtl. Control,
when the legislature statutorily invests an agency with certain functions, duties and responsibilities, the agency has a legislatively conferred interest in such matters. From this it must follow that, unless the legislature has provided otherwise, such an agency has an implicit power to be a litigant in matters touching upon its concerns. In such circumstances the legislature has implicitly ordained that such agency is a proper party litigant, i.e., that it has “standing.”

We also observe that pursuit of injunctive relief in a judicial forum represents a restrained and supervised form of administrative action, as compared, for example, to the issuance of some form of direct agency mandate, restraint, or sanction.
Compare Scheble v. Missouri Clean Water Comm’n,
*500
We hold, therefore, that the General Assembly has implicitly conferred upon the Department the capacity to seek redress in a judicial forum to restrain operation of an unlicensed airport.

The order of the Commonwealth Court is reversed and the case is remanded for further proceedings consistent with this opinion. .
Notes
. Section 471.3 provides for the licensing of airports and states in pertinent part that ‘‘[n]o person may establish, maintain or operate an airport, nor conduct flight operations at an airport, unless authorized to do so by the Bureau [of Aviation, a division of the Department].” 67 Pa.Code § 471.3. Section 471.2 of the same title defines ''airport” as:
[a]n area of land or water which is used, or intended to be used[,] for the landing and takeoff of aircraft and appurtenant areas which are used, or intended to be used, for airport buildings or air navigation facilities or rights-of-way, together with airport buildings and facilities thereon. The term includes heliports and public airports.
67 Pa.Code § 471.2. This definition is virtually identical to that provided in Section 5102 of the Aviation Code, 74 Pa.C.S. § 5102.
. Since the Aviation Code directs the Department to promulgate and enforce regulations necessary to execute its mandates,
see
74 Pa.C.S. § 5301(a), the courts implied that, had it promulgated a regulation enunciating its intention to seek injunctive relief against unlicensed airport operations, this may have been sufficient to preserve the Department’s claim in the judicial forum.
See Beam,
. As the common pleas court’s holding embodies purely a legal conclusion, the applicable standard of review focuses upon whether, in granting summary judgment to Beam, the common pleas court committed an error of law,
see Murphy v. Duquesne Univ. of the Holy Ghost,
. The stalutes cited by Beam are 74 Pa.C.S. § 5301(e), discussed infra; 74 Pa.C.S. § 5501(b), imposing a fine or thirty days’ imprisonment for unauthorized use ol' a public airport; and 74 Pa.C.S. § 5701(a), (b), making it a summary offense to erect structures within the approach area or in close proximity to an airport without prior approval.
. Beam also argues that we may affirm the Commonwealth Court on grounds that that court did not reach, namely, that his airfield is not an airport which, under the applicable statute and regulations, must be licensed. However, Section 471.5 of the pertinent regulations includes, as a category of airports to be licensed, a private, individual airport, that is, "[a] private airport used exclusively by the licensee." 67 Pa.Code § 471.5(a)(2)(f). Further, while some other jurisdictions exempt certain personal use airports from licensing requirements, see, e.g., Neb.Rev.Stat. § 3-136 (providing licensing exemption for restricted landing areas designed for personal use); cf. ORS 830.080 (delegating to a state administrative agency the authority to waive statutory licensing requirements based upon a finding of undue burden and consistency with the public safety), Pennsylvania law contains no statutory analogue.
. A number of jurisdictions hold that authority given to an agency should be liberally construed in order to permit the agency to carry out its statutory responsibilities, and incidental powers should be readily implied.
See
2 Am.Jur.2d Administrative Law § 58. While we acknowledge that some general principles of statutory interpretation militate in favor of such a view,
see
1 Pa.C.S. § 1928(c), this Court is not alone in maintaining the more restrained approach,
see, e.g., City of New York v. City Civil Serv. Comm’n,
. The other limilátions concern the licensing of new airports within a five-mile radius of an existing airport, as well as the conversion of military airports to joinl use, see 74 Pa.C.S. § 5301(e)(1), and the utilization ol the statewide regional apportionment formula, see 74 Pa.C.S. § 5302(e)(3).
. In furtherance of the legislative directives, the Department has promulgated the regulations codified in Chapter 471 of Title 67 of the Pennsylvania Code. Principally, Section 471.3(a), as noted earlier, see supra note 1, declares that, with certain exceptions not applicable here, “[n]o person may establish, maintain or operate an airport, nor conduct flight operations at an airport, unless authorized to do so by the Bureau [of Aviation].” 67 Pa.Code § 471.3(a). Section 471.3 provides further that the authorization granted by the Bureau may be suspended or revoked for reasonable cause, such as failure to correct deficiencies or to cease unauthorized activities. See 67 Pa.Code § 471.3(g). The regulations also specify fees for on-site inspections and licensing, see 67 Pa.Code § 471.4; establish rating categories for airports and heliports, see 67 Pa.Code §§ 471.5, 471.6; list requirements applicable to licensed airports and heliports, such as operating the facility safely and notifying the Bureau of hazardous conditions, see 67 Pa.Code § 471.7; provide a schedule of penalties, consisting of warnings, suspensions, and revocations, for specified violations, see 67 Pa.Code § 471.8; and, finally, provide for appeals from the Bureau’s decisions granting, denying, or revoking licenses, see 67 Pa.Code § 471.9. Although generally comprehensive, this regulatory scheme, like the statute authorizing its promulgation, does not explicitly confer upon the Department a capacity to seek injunctive relief.
. For example, Section 5301(e), authorizing the Department to revoke a license upon proof of statutory or regulatory violation, evidences that intention. Pursuant to statutory direction, the Department has promulgated regulations declaring the operation of an unlicensed airport to be unlawful, see 67 Pa.Code § 471.3(a), and specifying the penalties, culminating in revocation of the license, to be imposed for initial and subsequent violations of licensing requirements, see 67 Pa.Code § 471.8.
. This Court’s decision in
Commonwealth v. Cunningham,
. It is noteworthy that the absence of a specific regulation did not deprive Beam of due notice of the Department’s intention to proceed against him. By letters sent one and one-half years before, and one month before, the filing of the complaint in equity and petition for injundive relief, the Department informed Beam that it would pursue this legal remedy if he did not obtain a license for his airport.
