In this original proceeding, the petitioners, West Virginia Highlands Conservancy, Inc., West Virginia Wildlife Federation, West Virginia Council, Trout Unlimited, Inc., and West Virginia Citizen Action Group (hereinafter “petitioners”) seek a writ of mandamus compelling the respondents, the West Virginia Division of Environmental Protection and its Director, David C. Callaghan, (hereinafter “DEP”) to acknowledge their mandatory, nondiscretionary duty to treat acid mine drainage (hereinafter “AMD”) from bond forfeiture sites and to treat acid mine drainage at the highest priority sites, by any effective means, up to the statutorily established financial limits of the Special Reclamation Fund (hereinafter “SRF”).1
I
The provisions of the federal Surface Mining Control and Reclamation Act, 30 U.S.C. 1201, et seq. (hereinafter “SMCRA”) and the West Virginia Surface Coal Mining and Reclamation Act, W.Va.Code, 22A-3-1, et seq.2 (hereinafter “WVSCMRA”) are an attempt to deal with the adverse effects of surface and underground coal mining operations on unre-claimed lands. See 30 U.S.C. 1201(c), (h) (1988); W.Va.Code, 22A-3-2(a) [1985], Among the environmental problems is that of AMD,3 which pours into West Virginia’s streams and lakes from abandoned or forfeited mine sites, destroying aquatic life and impairing the natural beauty and enjoyment of the state’s waters.
On December 31,1993, the DEP submitted to the 1994 legislature an Acid Mine Drainage Bond Forfeiture Report (hereinafter “DEP Report”)4 concerning reclamation costs of treating AMD at bond forfeiture sites. The DEP report identifies 89 abandoned forfeited coal mine sites which currently discharge AMD into West Virginia streams. The DEP further states that bond forfeiture sites account for approximately 10% of the AMD5 affecting West Virginia’s watersheds.
The field study of AMD bond forfeiture sites, which is found in the DEP report, indicates that acid discharge from most sites *721would require simple chemical treatment systems,6 while other sites could be controlled by using passive treatment systems.7 The DEP further states that only a few sites are of high priority, requiring sophisticated chemical treatment facilities.8 Though the DEP is currently using these and other various methods of abatement, amelioration and prevention of AMD at bond forfeiture sites, it claims that it does not have a legal duty to do so.9
II
A review of the WVSCMRA and its corresponding regulatory scheme10 is necessary to determine the extent of the DEP’s legal duty to abate AMD which flows from forfeited mine sites into the state’s lakes and streams.
W.Va.Code, 22A-3-8 [1993] prohibits any person from engaging in surface mining operations without a DEP permit. See also 30 U.S.C. 1256(a) (1988). A permit application must contain, inter alia, the name of the watershed and location of the surface stream into which drainage will be discharged; a determination of the probable hydrologic consequences of the mining and reclamation operations; a map or plan indicating the location of a water treatment facility or drainage system; and a chemical analysis of potentially acid-forming sections of the overburden. W.Va.Code, 22A-3-9(a)(10), (11), (13)(L) and (14)(D) [1991].
A permit application must also include a reclamation plan. W.Va.Code, 22A-3-9(a)(16) [1991]. Each reclamation plan must demonstrate that reclamation required by WVSCMRA can be accomplished and must include, inter alia, “[t]he steps to be taken to comply with applicable air and water quality laws[.]” W.Va.Code, 22A-3-10(a)(8) [1991]. Furthermore, 38 West Virginia Code of State Regulations § 2 — 3.22(f) (1991)11 states, in relevant part, that each permit application “shall contain a hydrologic reclamation plan” which, inter alia, meets “applicable Federal *722and State water quality laws and regulations!;.]” 12
The DEP may not issue a mining and reclamation permit until the applicant files a performance bond covering “that area of land within the permit area upon which the [applicant] will initiate and conduct surface coal mining13 and reclamation operations” and in an amount “sufficient to assure the completion of the reclamation plan if the work [is] to be performed by the [DEP] in the event of forfeiture[.]” 30 U.S.C. 1259(a) (1988) (footnote added).14 Under WVSCMRA, the DEP may issue site-specific performance bonds. W.Va.Code, 22A-3-lla [1991].15 The amount of these bonds, which cannot exceed $5,000 per acre, must reflect the various factors which affect the cost of reclamation. W.Va. Code, 22A-3-lla(c)(l) and (3) [1991], One of those factors is “the potential for degrading or improving water quality.” W.Va.Code, 22A-3-lla(c)(3)(E) [1991],
As an option to the site-specific bonding program set forth in 30 U.S.C. 1259(a) (1988), the SMCRA allows states to develop an “alternative system that will achieve the objectives and purposes of the bonding program” required by the SMCRA. 30 U.S.C. 1259(c) (1988). As indicated above, those objectives and purposes include sufficient funds to complete reclamation if, in the event the site is forfeited, reclamation must be performed by the DEP.
West Virginia’s alternative system, which has been approved by the Office of Surface Mining Reclamation and Enforcement (hereinafter “OSM”),16 has set the amount of a performance bond at $1000 per acre. W.Va. Code, 22A-3-ll(a) [1990], Bond liability continues for the full term of the permit plus *723any additional period necessary to comply with the reclamation plan. W.Va.Code, 22A-3-ll(b) [1990]. If a performance bond is forfeited and the bond proceeds used by the DEP to complete reclamation are less than the actual cost of reclamation, the DEP is required to utilize monies from the Special Reclamation Fund (hereinafter “SRF”) in order to complete reclamation. W.Va.Code, 22A-3-ll(g) [1990];17 38 W.Va.C.S.R. § 2-12.4 (1991).18 As indicated in W.Va.Code, 22A-3-ll(g) [1990], our legislature has authorized the expenditure of up to twenty-five percent of the annual amount of the SRF for water quality improvement and, further, has specifically stated that “completion of reclamation” does not occur until “all applicable effluent and applicable water quality standards are met[.]”19 38 W.Va.C.S.R. § 2-2.35 (1991).20
In State ex rel. Laurel Mountain v. Callaghan, 187 W.Va. 266, 418 S.E.2d 580 (1992), this Court held that, pursuant to 38 W.Va. C.S.R. § 2-12.4(c) (1991),21 the DEP has a duty to utilize the proceeds from forfeited bonds to accomplish the completion of reclamation. Id. at syl. pt. 2. We further indicated that this regulation concerning the use of forfeited bonds to complete reclamation “operates to eliminate acid mine drainage at levels that would violate effluent limitations, thus furthering the legislative finding that ‘it is essential to the economic and social well-being of the citizens of the state of West Virginia to strike a careful balance between the protection of the environment and the *724economical mining of coal needed to meet energy requirements.’ W.Va.Code, 22A-3-2 [1985].” Id. at 270, 418 S.E.2d at 584 (footnote omitted).
In Laurel Mountain, we indicated that 88 W.Va.C.S.R. § 2-12.4(d) (1991)22 did not apply to that case and, consequently, we did not address the question of whether the DEP has a mandatory, nondiseretionary duty to use funds from the SRF to treat AMD.23 However, we did indicate that the treatment of AMD was a component of reclamation, a conclusion clearly supported by W.Va.Code, 22A-3-9 [1991], 88 W.Va.C.S.R. § 2-2.35 (1991)24 and 38 W.Va.C.S.R. § 2-3.22© (1991).25 The treatment of AMD is a component of reclamation and the DEP has a mandatory duty to use the proceeds from forfeited bonds to complete reclamation. It follows, therefore, that the DEP has a similar mandatory duty to treat AMD, when it is required for reclamation, with up to the statutorily established financial limit of 25% of the annual amount in the SRF. W.Va.Code, 22A-3-ll(g) [1990]. We recognize that funds annually available in the SRF are limited26 and that the costs of treating AMD from forfeited mine sites may exceed the 25% of the SRF allotted for the treatment of water systems. Therefore, the DEP, in its discretion, is entitled to prioritize those AMD bond forfeiture sites which it deems to be in the most need of treatment and to expend the available money in the SRF accordingly.27
We hold, therefore, that pursuant to W.Va. Code, 22A-3-ll(g) [1990] and 38 W.Va.C.S.R. § 2-12.4(d) (1991), the DEP has a mandatory, nondiscretionary duty to utilize moneys from the SRF, up to 25% of the annual amount, to treat AMD at bond forfeiture sites when the proceeds from forfeited bonds are less than the actual cost of reclamation. However, when the cost of treating AMD at these sites is greater than the amount of funds available in the SRF, the DEP may expend the available funds in the SRF at the highest priority sites.
Consistent with the foregoing, the petitioners’ writ of mandamus is hereby granted.
Writ granted.
