*636 OPINION
The Supreme Court of the . United States petitioned this Court for certification of a question of Pennsylvania law.

Writing for the Supreme Court, Justice Breyer sought certification for us to opine whether the interpretation of 35 P.S. § 6018.401(a),

set forth in
Commonwealth v. Scarpone,
FACTS AND PROCEDURAL HISTORY
William Fiore was the owner and operator of the Municipal and Industrial Disposal Company (MIDC) in Elizabeth Township, Allegheny County. In 1970, the Department of Environment Resources (DER), now the Department of Environmental Protection (DEP), 3 issued a permit to MIDC for the *637 temporary storage of solid and hazardous wastes, specifically fly ash from a power station. The permit provided, in detail, the manner in which MIDC could store waste and dispose of collected leachate. It did not authorize any off-site discharge of hazardous waste from the facility. Per the permit, MIDC installed monitoring systems to detect the presence of unpermitted waste discharge. DER subsequently amended the temporary permit, allowing the additional storage of demolition and industrial waste and extending the permit until 1982.
Following laboratory tests conducted from 1982 through 1983, DER informed Fiore that hazardous chemicals were migrating from his storage facility. Specifically, DER had discovered the presence of Benzene, Toluene, and Xylene (organic chemicals) in water discharging from MIDC. 4 In response to its findings, DER required MIDC to apply for a National Pollutant Discharge Elimination System (NPDES) permit. DER issued the NPDES permit to MIDC in December of 1983. The NPDES permit established a maximum level of allowable hazardous waste discharge from the facility. To circumvent the discharge restrictions, the general manager of MIDC, David Scarpone, acting pursuant to Fiore’s instruction, directed two welders to modify a mine water discharge pipe. This modification allowed MIDC to control both the discharge of uncontaminated and contaminated waters and allow the flow of hazardous waste through the monitoring wells when detection by DER officials was unlikely.
In July of 1984, a DER inspector discovered an illegal modification. The Commonwealth subsequently filed multiple criminal charges against both Fiore and Scarpone. In 1986, the Commonwealth tried Fiore and Scarpone jointly before a jury in a trial limited to charges against both defendants. Later that same year, in a bench trial, Fiore was tried on charges not involving Scarpone. Among other offenses, a jury convicted Fiore and Scarpone of “operating a hazardous waste *638 storage, treatment or disposal facility” without a “permit.” 35 P.S. § 6018.401(a). Although the Commonwealth conceded that both men had a permit to operate MIDC, the trial court accepted the prosecution’s argument that their intentional alteration of the facility was such a significant departure from the terms of the permit that the operation of MIDC was without a permit. Only Fiore’s conviction for violating Section 6018.401(a) of the Solid Waste Management Act 5 (SWMA) is at issue. 6 For Fiore’s two counts of violating Section 6018.401(a), the trial court imposed two sentences, each of one-half to five years imprisonment, ten years probation, and a fine of $100,000, to run consecutively.
Fiore appealed to the Superior Court, which, acting
sua sponte,
removed the matter to the Commonwealth Court,
7
indicating that, pursuant to 42 Pa.C.S. § 762(a)(2)(ii),
8
the Commonwealth Court possesses exclusive jurisdiction over appeals involving criminal proceedings, which arise from violations of regulatory statutes administered by Commonwealth
*639
agencies. Acting on a Petition from Fiore, the Commonwealth Court transferred his appeal back to the Superior Court because the court found that the facts and issues of Fiore’s appeal were closely related to another appeal taken by him to the Superior Court. In an unpublished memorandum decision, filed May 12, 1989, the Superior Court affirmed his Judgment of Sentence.
Commonwealth v. Fiore,
Scarpone, likewise, appealed his case to the Superior Court. However, after the Superior Court
sua sponte
transferred his appeal to the Commonwealth Court, Scarpone did not request a transfer back to the Superior Court. Thus, the Commonwealth Court heard the appeal of Scarpone. On August 5, 1991, the Commonwealth Court reversed his conviction on the charge of violating Section 6018.401(a).
Scarpone v. Commonwealth,
Reacting to our decision in
Scarpone,
Fiore filed his second emergency application for extraordinary relief. He had filed his first in 1992, which we denied. He again requested that we take jurisdiction pursuant to the King’s Bench powers, 42 Pa.C.S. § 726.
9
We denied Fiore’s second application on
*640
March 22, 1994. Fiore next sought relief under the Post Conviction Relief Act (PCRA),
10
claiming that he was convicted of violating Section 6018.401(a), on facts that this Court has ruled are not a crime. On August 18, 1994, the PCRA court issued an Order, denying his Petition for collateral relief. Fiore appealed the decision of the PCRA court to the Superior Court, which affirmed with a published Opinion on September 20, 1995.
Commonwealth v. Fiore,
Having extinguished his grounds for relief in the Commonwealth, Fiore filed a Petition for Federal Writ of Habeas Corpus, claiming that (1) the trial court convicted, sentenced, and incarcerated him on facts that did not constitute each element of 35 P.S. § 6018.401(a) and (2) the courts of Pennsyl *641 vania denied him his federal rights of due process and equal protection by not applying our decision in Scarpone to his case. Acting on the Federal Magistrate’s recommendation, the United States District Court for the Western District of Pennsylvania granted the writ.
The Commonwealth appealed to the United States Court of Appeals for the Third Circuit, which reversed the federal District Court.
Fiore v. White,
Fiore petitioned the Supreme Court of the United States for a grant of certiorari to review his Fourteenth Amendment Due Process Clause issue. U.S. Const, amend. XIV. On March 29, 1999, the Supreme Court granted certiorari.
Fiore v. White,
DISCUSSION
Fiore takes the position that Scarpone did not issue a new rule of law. He claims that we merely provided our first interpretation of an unambiguous statute. According to Fiore, Scarpone explained the intent of the legislature that Section 6018.401(a) of the SWMA requires operators of hazardous *642 waste facilities to possess a permit. Because that statutory provision was clear on its face, and Scarpone did not overrule any legal precedent, he argues that our interpretation of Section 6018.401(a) is an expression of the law from the date of the enactment of that statute. Fiore explains that fundamental fairness ánd constitutional protections necessitate against allowing our society to incarcerate a defendant, who was tried in a joint trial, for the same actions, committed by a co-defendant, which we deemed did not violate Section 6018.401(a).
The Commonwealth argues that
Scarpone
created a 'new rule of law. In Pennsylvania, it is well established that a new rule of law will not apply retroactively “to any case on collateral review unless that decision was handed down during the pendency of appellant’s direct appeal and the issue was properly preserved there, or ... was nonwaivable.”
Commonwealth v. Gillespie,
*643
Not every opinion creates a new rule of law. Generally, where we have yet to rule explicitly on an unresolved legal issue, the first decision providing a definitive answer announces a new rule of law.
See Todaro,
A decision does not articulate a new rule of law when it “merely reliefs] upon a statutory interpretation which was not wholly without precedent.”
McCloskey,
There can be no change to statutory law when there has been no amendment by the legislature and no prior decision by this Court. Only the legislature has the authority to promulgate legislation. Our role is to interpret statutes as enacted by the Assembly. We affect legislation when we affirm, alter, or overrule our prior decisions concerning a statute or when we declare it null and void, as unconstitutional. Therefore, when we have not yet answered a specific question about the meaning of a statute, our initial interpretation does not announce a new rule of law. Our first pronouncement on the substance of a statutory provision is purely a clarification of an existing law.
Prior to our opinion in
Scarpone,
we had not examined Section 6018.401(a) of the SWMA. The only cases involving that statutory provision were the unpublished memorandum opinion from the Superior Court in its review of Fiore’s direct appeal and the Commonwealth Court’s published decision in
*645
Scarpone.
As justification for accepting allowance of appeal,
12
we recognized in
Scarpone
that “[t]he two courts are clearly in conflict and this leaves the Attorney General’s office ill-advised on how it should proceed in such situations.”
Scarpone,
We did not provide a lengthy justification for our holding that the Commonwealth failed to prove all of the elements of Section 6018.401(a) against Scarpone. Our basis consisted of a common-sense reading of the statute and the Rules of Statutory Construction.
See Scarpone,
*646
Scarpone
did not announce a new rule of law. Our ruling merely clarified the plain language of the statute. Consequently, we answer the certified question in the affirmative. Our interpretation of 35 P.S. § 6018.401(a) in
Scarpone,
CONCLUSION
Accordingly, having answered the question that we certified for review, we refer this matter back to the Supreme Court of the United States.
Notes
. Pursuant to this Court’s Internal Operating Procedures, we may accept certification of questions from the Supreme Court of the United States. See 204 Pa.Code § 29.451; Internal Operating Procedures, Rules Regarding Certification of Questions of Pennsylvania Law.
. 35 P.S. § 6018.401(a) provides the following:
(a) No person or municipality shall store, transport, treat, or dispose of hazardous waste within this Commonwealth unless such storage, transportation, treatment, or disposal is authorized by the rules and regulations of the department; no person or municipality shall own or operate a hazardous waste storage, treatment or disposal facility unless such person or municipality has first obtained a permit for the storage, treatment and disposal of hazardous waste from the department; and, no person or municipality shall transport hazardous waste within the Commonwealth unless such person or municipality has first obtained a license for the transportation of hazardous waste from the department.
. The legislature renamed "the Department of Environmental Re- , sources” to "the Department of Environmental Protection,” effective July 1, 1995. 71 P.S. § 1340.501.
. Benzene, Toluene, and Xylene are listed as hazardous substances, pursuant to the Comprehensive Environmental Response Compensation and Liability Act of 1980, as amended 42 U.S.C. 9601 et seq. 40 C.F.R. § 261.33 (2000).
. Act of July 7, 1980, P.L. 380, 35 P.S. § 6018.101 etseq.
. Fiore’s two trials resulted in convictions of sixty counts of violations of the SWMA and other statutes.
. Pursuant to 42 Pa.C.S. § 705, the Superior Court and the Commonwealth Court have the authority to transfer appeals. 42 Pa.C.S. § 705 provides the following:
The Superior Court and the Commonwealth Court shall have power pursuant to general rules, on their own motion or upon petition of any party, to transfer any appeal to the other court for consideration and decision with any matter pending in such other court involving the same or related questions of fact, law or discretion.
. 42 Pa.C.S. § 762(a)(2) provides the following:
(a) General rule. — Except as provided in subsection (b), the Commonwealth Court shall have exclusive jurisdiction of appeals from final orders of the courts of common pleas in the following cases:
(2) Governmental and Commonwealth regulatory criminal cases.— All criminal actions or proceedings for the violation of any:
(i) Rule, regulation or order of any Commonwealth agency.
(ii) Regulatory statute administered by any Commonwealth agency
subject to Subchapter A of Chapter 5 of Title 2 (relating to practice and procedure of Commonwealth agencies). The term “regulatory statute” as used in this subparagraph does not include any provision of Title 18 (relating to crimes and offenses).
. 42 Pa.C.S. § 726 provides the following:
§ 726 Extraordinary jurisdiction
Notwithstanding any other provision of law, the Supreme Court may, on its own motion or upon petition of any party, in any matter pending before any court or district justice of this Commonwealth involving an issue of immediate public importance, assume plenary *640 jurisdiction of such matter at any stage thereof and enter a final order or otherwise cause right and justice to be done.
. Act of May 13, 1982, P.L. 417, last amended, January 27, 1998, P.L. 20, 42 Pa.C.S. § 9541-9546.
The scope of the PCRA is stated, thus:
This subchapter provides for an action by which persons convicted of crimes they did not commit and persons serving illegal sentences may obtain collateral relief. The action established in this subchapter shall be the sole means of obtaining collateral relief and encompasses all other common law and statutory remedies for the same purpose that exist when this subchapter takes effect, including habeas corpus and coram nobis. This subchapter is not intended to limit the availability of remedies in the trial court or on direct appeal from the judgment of sentence, to provide a means for raising issues waived in prior proceedings or to provide relief from collateral consequences of a criminal conviction. Except as specifically provided otherwise, all provisions of this subchapter shall apply to capital and noncapital cases.
42 Pa.C.S. § 9542.
. It must be noted that when we issued
Office of Disciplinary Counsel v. Anonymous Attorney A,
. According to our Rules of Appellate Procedure:
Except as prescribed in Rule 1101 (appeals as of right from the Commonwealth Court), review of a final order of the Superior Court or the Commonwealth Court is not a matter of right, but of sound judicial discretion, and an appeal will be allowed only when there are special and important reasons therefor.
