OPINION
LARSEN, Justice.On May 2, 1980, the Commonwealth of Pennsylvania, Department of Environmental Resources (DER) issued a permit for solid waste disposal and/or processing facility (Permit No. 300728) to Elwins Farms, Incorporated. The permit pertains to a facility called Elwin Farms Industrial Residue Processing Site located in Franklin Township, Fayette County, Pennsylvania. The permit was issued pursuant to an application received by the DER on September 11, 1979. It allowed and authorized the permitee to “stabilize and dispose of (using the ‘Stabatrol Process’ as described in the approved Facility Design and Operations Plans) neutralized inorganic sludges/residues with a solids content of 12% or greater, by weight, which do not contain (1) organic solvents, (2) sodium salts of arsenate, borate, phosphate, iodate, and/or sulfides, (3) more than 1% oil and grease.” The baneful deposits sanctioned by this license are acknowledged to be toxic wastes which perpetually retain their hazardous toxicity.
On May 30, 1980, a timely appeal from the issuance of the permit was filed with the Environmental Hearing Board (EHB) by Franklin Township and Fayette County. The appeal was based, inter alia, on the following: (a) that the DER failed to establish permanent disposal within thirty (30) days as a requirement of the permit; (b) that proper *165consideration was not accorded to the existence of a high pressure gas line which runs across the subject property; (c) that the applicant furnished false, misleading, and fraudulent information in its application for a permit; (d) that no provisions for accidental spillage of large quantities of waste were provided; (e) that no consideration was given to the problem of transportation of the waste materials to and from the site; (f) that neither the applicant nor the owner of the land possess the mineral rights creating the possibility of future mining operations beneath the surface; (g) that there is no method to insure that unauthorized materials will not be deposited at the site; (h) that there are several springs and seeps on the property which could become contaminated; (i) that the “stabatrol process” is not an established proven method; (j) that the land on which the facility is to be operated is not zoned for the activity proposed; (k) that the DER failed to notify the township and the county of the application for a permit and breached its duty to cooperate with the local government units in discharging its duties under the Solid Waste Management Act.1
On motion of the permitee, El win Farms, Inc., the EHB dismissed the appeal on the basis that the township and the county lack standing to challenge the permit’s issue. The Commonwealth Court, relying on its opinions in Susquehanna County v. Commonwealth of Pennsylvania, Department of Environmental Resources, 58 Pa.Common. 381, 427 A.2d 1266 (1981) and Strasburg Associates v. Newlin Township, 52 Pa.Common. 514, 415 A.2d 1014 (1980), affirmed the Order of the EHB dismissing the appeal for lack of standing on the part of the appellants. Upon petition, we granted allocatur.
The question of standing is rooted in the notion that for a party to maintain a challenge to an official order or action, he must be aggrieved in that his rights have been invaded or infringed. This principle was thoroughly considered in Wm. Penn Parking Garage v. City of Pittsburgh, *166464 Pa. 168, 346 A.2d 269 (1975) where this court confirmed that to have standing, a party must (a) have a substantial interest in the subject-matter of the litigation; (b) the interest must be direct; and (c) the interest must be immediate and not a remote consequence.
In Wm. Penn Parking Garage, supra, 464 Pa. 191-192-193, 346 A.2d 269, 280-281, this Court stated:
“ ‘[The party] must have a direct interest in the subject-matter of the particular litigation, otherwise he can have no standing to appeal. And not only must the party desiring to appeal have a direct interest in the particular question litigated, but his interest must be immediate and pecuniary, and not a remote consequence of the judgment. The interest must also be substantial’. Keystone Raceway Corp. vs. State Harness Racing Commission, 405 Pa. 1, 7-8, 173 A.2d 97, 100 (1961).”
“The core concept, of course, is that a person who is not adversely affected in any way by the matter he seeks to challenge is not ‘aggrieved’ thereby and has no standing to obtain a judicial resolution of his challenge. In particular, it is not sufficient for the person claiming to be “aggrieved” to assert the common interest of all citizens in procuring obedience to the law.”
“It is the latter principle which lies behind the traditional . formulation’s requirement that the would-be “aggrieved” party must have an interest which is “pecuniary” and “substantial”. Thus, for example, it is clear that some interests will suffice to confer standing even though they are neither pecuniary nor readily translatable into pecuniary terms.”
On the federal level, where review of federal agency action is sought, the standing requirement has been broadened to include persons who can show “that the challenged action had caused them “injury in fact” and where the alleged injury was to an interest ‘arguably within the zone of interests to be protected or regulated’ by the statutes that the agency was claimed to have violated.” Sierra Club v. *167Morton, 405 U.S. 727, 92 S.Ct. 1361, 31 L.Ed.2d 636 (1972); Also see: U.S. v. Students Challenging Regulating Agency-Procedures, 412 U.S. 669, 93 S.Ct. 2405, 37 L.Ed.2d 254 (1973).
The appellants, Franklin Township and Fayette County are legal persons in the sense that they exist as legal entities possessed of rights and responsibilities including the right and sometimes the duty to seek judicial or other legal relief. However, a township and a county are more than abstract entities; each is also a place populated by people. They can be identified by fixed and definable political and geographic boundaries. These boundaries encompass a certain natural existence — land, water, air, etc. collectively referred to as environment. Whatever affects the natural environment within the borders of a township or county affects the very township or county itself. Toxic wastes which are deposited in the land irrevocably alter the fundamental nature of the land which in turn irrevocably alter the physical nature of the municipality and county of which the land is a part. It is clear that when land is changed, a serious risk of change to all other components of the environment arises. Such changes and threat of changes ostensibly conflict with the obligations townships and counties have to nature and the quality of life. We believe that the interest of local government in protecting the environment, which is part of its physical existence, is “substantial” within the meaning of “substantial interest” as set forth in Wm. Penn Parking Garage, supra.2 Aesthetic and environmental well-being are important aspects of the quality of life in our *168society,3 and a key role of local government is to promote and protect life’s quality for all of its inhabitants. Recent events are replete with ecological horrors that have damaged the environment and threatened plant, animal and human life. We need only be reminded of the “Love Canal” tragedy4 and many like situations faced by communities and local governments across the country to recognize the substantial local concerns.
One of the most pressing public issues of the 1980’s is the prudent establishment of waste treatment facilities and disposal sites. It is crucial that such sites be established in an efficient fashion, at a minimal cost to society, and within the framework of providing maximum protection of public health and property rights.5 This laudable and imperative *169goal can best be accomplished through the combined efforts of the citizenry and government. Cooperation between and among all who have an “interest” in the environment is essential to achieve the aims of minimal cost and maximum protection.6
We have found that the interest of local government in the natural surroundings is not insubstantial. We shall now consider whether the “direct” and “immediate” requirements of standing are satisfied in this case. In Wm. Penn Parking Garage, supra., we said: “The requirement that an interest be ‘direct’ simply means that the person claiming to be aggrieved must show causation of the harm to his interest by the matters of which he complains.”
Changing the inherent character and quality of the environment by the introduction of toxic wastes into the land, amply provides local government units with an interest which is direct in every meaningful sense. The same considerations which led us to the conclusion that the interest of local government in its physical attributes is substantial, apply in the determination that the interest is also direct. As we have noted, among the responsibilities of local *170government is the protection and enhancement of the quality of life of its citizens.7 Indeed, it is a constitutional charge *171which must be respected by all levels of government in the Commonwealth.8
Under section 504 of the “Solid Waste Management Act”, 1980, July 7, P.L. 380, No. 97 § 504, 35 P.S. 6018.504, consultation and cooperation with local governing bodies is required.9 If the DER neglected to comply with this requirement and failed or refused to afford the local governments an opportunity to review an application for a permit, it seems clear that, under such circumstances, the propriety of a challenge by the local government units could not be denied. We are aware that this provision of the current statute calling for cooperation is a recent enactment and was not a part of the prior law10 in effect at the time of the issuance of the permit to Elwin Farms, Inc. Nonetheless, the cooperation mandated by the present Act is a statutory recognition of the ever-existing direct and substantial interest local governing bodies have in the character and quality of the environment.
The direct and substantial interest of local government in the environment, and in the quality of life of its citizenry cannot be characterized as remote. We need not wait until an ecological emergency arises in order to find that the *172interest of the municipality and county faced with such a disaster is immediate.
When a toxic waste disposal site is established, undoubtedly there is an instantaneous change in the land on which it is located, and an immediate risk to the surrounding environment and quality of life. These critical matters must be addressed by local government without delay. The environment which forms a part of the physical existence of the municipality or county has been altered and immediate attention must be given to the changed character if the local government is to properly discharge its duties and responsibilities. Furthermore, in the event of an environmental emergency, the local municipality and county would be the first line of containment and defense.
Franklin Township and Fayette County have a substantial, direct and immediate interest in the establishment and operation of a toxic waste landfill within its boundaries so as to give each standing to challenge the issuance of a permit.11
The Order of the Commonwealth Court is reversed and this case is remanded to the Environmental Hearing Board for proceedings consistent with this opinion.

. “The requirement of a “substantial” interest simply means that the individual’s interest must have substance — there must be some discernible adverse effect to some interest other than the abstract interest of all citizens in having others comply with the law. The requirement that the interest be “pecuniary” which may once have had independent significance, no longer adds anything to the requirement of an interest having substance, as defined above.” Wm. Penn Parking Garage, Inc. v. City of Pittsburgh, 464 Pa. 168, 346 A.2d 269 (1975).

. A national emergency was declared at the Love Canal area of Niagara Falls, New York in August, 1978 because toxic chemicals deposited in the ground decades earlier were surfacing. The State of New York purchased the homes of approximately 240 families whose property adjoined the contaminated site and provided relocation services for them. ENV’T Reporter, August 11, 1978, Vol. 9, No. 15, p. 581.
In May, 1980, President Carter declared a state of emergency at Love Canal and over 700 families, who may have been exposed to the toxic wastes, were temporarily relocated. ENV’T Reporter, May 30, 1980, Vol. 11, No. 5, p. 139.
. “At present, there are approximately 55,000 different chemical substances in commercial use in the United States. In 1980, the chemical industry’s annual sales were $162 Billion — more than 5 percent of the gross national product.”
“One of the perplexing problems of modern life is that sometimes, and under some condition, some of the chemical substances we depend on can produce unwanted effects. When people speak of “chemicals” many think in terms of synthetic organic chemicals. This view is too narrow to meet the demands of environmental toxicologists. All types of chemical substances may be considered as potentially toxic. These substances can be as diverse as metal ore tailings, solvents, corrosives, inorganic salts and various elemental substances such as lead or phosphorus. Even a substance found on anyone’s dinner table — common salt (NaCl) — could have serious *169environmental results if released in quantity to a small pond. The change in salinity could kill the fresh water fish and plants” Council on Environmental Quality, Environmental Quality, 1981. The 12th Annual Report of the Council of Environmental Quality (Washington D.C.: U.S. Government Printing Office, 1981) p. 115.
. This kind of cooperation between and among governments and governmental agencies is now a statutory requirement under the provisions of the Solid Waste Management Act, 1980, July 7, P.L. 380, No. 97 § 504, 35 P.S. 6018.504 which provides as follows:
“Applications for a permit shall be reviewed by the appropriate county, county planning agency or county health department where they exist and the host municipality, and they may recommend to the department conditions upon, revisions to, or disapproval of the permit only if specific cause is identified. In such case the department shall be required to publish in the Pennsylvania Bulletin its justification for overriding the county’s recommendations. If the department does not receive comments within 60 days, the county shall be deemed to have waived its rights to review.
. Examples of some of the duties which are associated with this important responsibility can be found in “The County Code”, 1955, Aug. 9, P.L. 323, § 2101, 16 P.S. § 2101; the “Local Health Administration Law”, 1951, Aug. 24, P.L. 1304 § 1 et seq., 16 P.S. § 12001 et seq., and “The Second Class Township Code”, 1933, May 1, P.L. 103, 1947, July 10, P.L. 1481, § 1 et seq., 53 P.S. § 65101, et seq.
The “County Code” provides: “The board of county commissioners may provide and annually appropriate from any moneys in the county treasury not otherwise appropriated such sum or sums as they deem necessary for the protection of the health, cleanliness, convenience, comfort and safety of the people of the county”. The County Code, 1955, Aug. 9, P.L. 323 § 2101, 16 P.S. § 2101.
The legislative findings and purposes as promulgated in the “Local Health Administration Law” provides in pertinent part as follows:
“The General Assembly of this Commonwealth has determined and hereby declares as a matter of legislative finding that:
(a) The protection and promotion of the health of the people in furtherance of human well-being, industrial and agricultural productivity and the national security is one of the highest duties of the Commonwealth.
(b) This cardinal duty can be performed only when adequate local public health services are available to all people of the Commonwealth, when these services are maintained at a high level of professional and technical performance, and when they are administered according to units of population sufficiently large to enable full time modem health services to be provided on the most economical basis by local communities working in partnership with the Commonwealth.” Local Health Administration Law, 1951, Aug. 24, P.L. 1304 § 1, 16 P.S. § 12001.
