delivered the opinion of the Court.
This case presents the Court once again with a question concerning a State’s ability to regulate the activities of natural gas companies.
*295 I
Respondents ANR Pipeline Company (Pipeline) and ANR Storage Company (Storage) are wholly owned subsidiaries of American Natural Resources Company (Resources), a Delaware corporation which, like Pipeline and Storage, has its principal place of business in Michigan. Both Pipeline and Storage are natural gas companies, within the meaning of the Natural Gas Act of 1938 (NGA or Act), ch. 556, 52 Stat. 821, as amended, 15 U. S. C. § 717 et seq. 1 Thus, both are subject to the jurisdiction of the Federal Energy Regulatory Commission (FERC), the regulatory body charged with implementation of the NGA. See § 1(b) of the Act, 15 U. S. C. § 717(b). 2 .
Pipeline is a Delaware corporation that owns and operates an interstate natural gas pipeline system transporting gas, exclusively for resale, to 51 gas distribution centers in Michigan and eight other States, where the gas is either delivered to customers of Pipeline or stored for future delivery. Pipe *296 line purchases its natural gas from producers in Texas, Oklahoma, Kansas, Louisiana, and Wyoming.
Storage, which operates independently from Pipeline, is a Michigan corporation organized by Resources in 1978 to develop and operate gas storage reservoirs for nonaffiliated customers. Storage receives gas from outside Michigan and, on demand, redelivers it for sale outside that State. Storage operates four storage fields in Michigan.
Petitioners are members of the Michigan Public Service Commission (MPSC). Under Michigan’s Public Utilities Securities Act, 1909 Mich. Pub. Acts No. 144, as amended (Act 144), Mich. Comp. Laws Ann. § 460.301 et seq. (1967 and Supp. 1987), 3 a public utility exercising or claiming the right *297 to transport natural gas in Michigan for public use 4 must obtain MPSC approval before issuing long-term securities. Act 144 directs the MPSC to approve a security issuance *298 when it “is satisfied that the funds derived . . . are to be applied to lawful purposes and that the issue and amount is essential to the successful carrying out of the purposes, or that the issue of the stock fairly represents accumulated and undistributed earnings invested in capital assets and not previously capitalized.” §460.301(3). The MPSC may conduct an investigation, including an appraisal of the company’s property at the company’s expense, in deciding whether to allow the issue, §460.301(2), and it “may impose as a condition of the grant reasonable terms and conditions that [it] considers proper. ” § 460.301(3).
Pipeline and Storage filed in the United States District Court for the Western District of Michigan an amended complaint against petitioners in their official capacities, seeking a declaratory judgment that the MPSC lacks jurisdiction over their security issuances and thus that they may lawfully issue and market securities without MPSC approval. 5 Respondents argued that Act 144 was pre-empted by the NGA and that Act 144 violates the Commerce Clause, U. S. Const., Art. I, § 8, cl. 3.
The District Court concluded that Act 144 was neither preempted by the federal regulatory scheme nor in violation of the Commerce Clause.
The United States Court of Appeals for the Sixth Circuit reversed, holding that both the pre-emptive effect of the federal regulatory scheme and the Commerce Clause bar application of Act 144 to respondents.

In this case we conclude that Act 144 regulates in a field the NGA has occupied to the exclusion of state law, and that it therefore is pre-empted.

State Corporation Comm’n of Kansas,
First, in exercising its authority to determine a “just and reasonable” rate for the transportation or sale of natural gas subject to its jurisdiction, FERC may conduct hearings and undertake a detailed examination of a company. § 4 of the NGA, as amended, 15 U. S. C. § 717c. For example, to calculate a reasonable rate of return on invested capital, FERC examines a company’s capital structure (the percentages of its capital that come from debt, common stock, and preferred stock), establishes the rate of return allowable on each type of capital, and determines an overall rate of return as a weighted average, in accordance with the amount of each kind of capital.
Public Service Comm’n of New York
v.
FERC,
259 U. S. App. D. C. 86, 96,
Second, a natural gas company must obtain from FERC a “certificate of public convenience and necessity” before it constructs, extends, acquires, or operates any facility for the transportation or sale of natural gas in interstate commerce. § 7(c)(1)(A) of the NGA, as amended, 15 U. S. C. § 717f (c)(1)(A). FERC will grant the certificate only if it finds the company able and willing to undertake the project in compliance with the rules and regulations of the federal regulatory scheme. § 7(e), as amended, 15 U. S. C. § 717f(e). FERC may attach “to the issuance of the certificate and to the exercise of the rights granted thereunder such reasonable terms and conditions as the public convenience and necessity may require.” Ibid. In fulfilling this statutory duty, FERC has promulgated extensive regulations that require a statement of the plans for financing a proposed facility and a detailed description of any proposed securities issuance. 18 CFR § 157.14(14) (1987). 7 FERC, like the Federal Power Com *303 mission, its predecessor, has not hesitated to use its certification power to ensure that a project is financed in accordance with the public interest. 8
*304 Third, FERC has various powers and obligations that both allow and require it to protect against the deleterious effects of ill-considered or improper securities issuances in this area. For example, officers and directors of natural gas companies are prohibited from profiting from the company’s securities issues. See § 12, 15 U. S. C. § 717k. No company may abandon any service or facility without FERC approval, including a finding by FERC that either the available gas supply is depleted, or “the present or future public convenience or necessity permit such abandonment.” § 7(b), 15 U. S. C. § 717f(b). A company must keep its accounts in accordance with FERC’s Uniform System of Accounts and must submit those accounts for review as FERC deems necessary. §§ 8 and 10, 15 U. S. C. §§ 717g and 717i; 18 CFR pt. 201 (1987). Finally, FERC has the authority to examine and to change “any rule, regulation, practice, or contract affecting [rates that] is unjust, unreasonable, unduly discriminatory, or preferential.” § 5(a), 15 U. S. C. § 717d(a).
Although the NGA gives FERC these substantial powers and obligations, it is also true, as petitioners remind us, that FERC is not expressly authorized to regulate the issuance of securities by natural gas companies. Of course, if such express authority were granted, pre-emption would be more apparent, given the comprehensive nature of FERC’s authority. In the absence of an express provision, however, we must examine whether the preissuance review of securities in which Michigan engages amounts to a regulation in the field of gas transportation and sales for resale that Congress intended FERC to occupy.
B
As an initial matter, respondents argue that Act 144 is preempted by the NGA because “[sjecurities issuances used to finance the interstate sale and transportation of natural gas were clearly beyond the power of the states to control in 1938.” Brief for Respondents 12. They premise this argument on this Court’s statements that Congress intended, by
*305
enacting the NGA, to cover areas of natural gas regulation that the States could not reach under the Court’s “dormant” Commerce Clause decisions. See,
e. g., Panhandle Eastern Pipe Line Co.
v.
Public Service Comm’n of
Indiana,
Even if Commerce Clause jurisprudence would have barred Act 144’s regulation at the time of the enactment of the NGA, an issue never directly settled by the Court, that would not decide this case. The authorities on which respondents rely state only what is now well settled: Congress occupied the field of matters relating to wholesale sales and transportation of natural gas in interstate commerce. See,
e. g., Illinois Gas Co.
v.
Central Illinois Public Service Co.,
Similarly, petitioners’ reliance on Congress’ subsequent failure to enact proposed legislation that would have given FERC explicit authority to regulate the issuance of securities of natural gas companies
9
deserves only passing mention. This Court generally is reluctant to draw inferences from Congress’ failure to act. See,
e. g., American Trucking Assns., Inc.
v.
Atchison, T. & S. F. R. Co.,
C
We turn then, to the crux of the issue: whether Act 144 is a regulation of the rates and facilities of natural gas companies used in transportation and sale for resale of natural gas in interstate commerce. Since we find that it is, we conclude that it is pre-empted.
*307
As noted earlier, Act 144 allows the MPSC to examine a security issuance of a natural gas company to determine whether it is “to be applied to lawful purposes and ... is essential to the successful carrying out of the purposes, [or] represents accumulated and undistributed earnings invested in capital assets and not previously capitalized.” Mich. Comp. Laws Ann. § 460.301(3) (Supp. 1987). The Michigan Supreme Court has authoritatively construed Act 144 as designed to protect investors in the gas company’s securities and to protect ratepayers.
Attorney General
v.
MPSC,
Petitioners argue that, without Act 144, a company could take on so much debt through securities issuances that it would lack the resources to maintain its Michigan facilities properly. This could threaten the supply of gas to Michigan consumers, petitioners argue, lead to a rate increase, or hurt investors in the company. In another scenario, a company might take on more equity than it needs, requiring it to charge higher rates (because equity usually requires a higher rate of return). Petitioners also explain that Act 144 protects against overcapitalization in the sense of a lack of correlation between a company’s capital stock and the value of its property. An imbalance in this respect, petitioners argue, could also threaten the supply of gas at reasonable rates. 10
*308 Each of these uses of Act 144, however, is an attempt to regulate matters within FERC’s exclusive jurisdiction. By-keeping a natural gas company from raising its equity levels above a certain point, Michigan seeks to ensure that the company will charge only what Michigan considers to be a “reasonable rate.” This is regulation of rates. The other aim of Act 144, seeking to ensure that a company is financed in a way that will allow proper maintenance of its facilities and continuance of its services, for the benefit of both ratepayers and investors, also falls within FERC’s exclusive purview since those facilities are a critical part of the transportation of natural gas and sale for resale in interstate commerce. In short, the things Act 144 regulation is directed at, the control of rates and facilities of natural gas companies, are precisely the things over which FERC has comprehensive authority. 11
Of course, every state statute that has some indirect effect on rates and facilities of natural gas companies is not preempted. Cf.
Metropolitan Life Ins. Co.
v.
Massachusetts,
Thus, while the NGA does not expressly grant FERC preissuance authority over the securities of natural gas companies, FERC achieves the regulatory ends of such review with regard to rates and facilities through the exercise of its express regulatory responsibilities.
*310 D
Our conclusion that Act 144 seeks to regulate a field that the NGA has occupied also is supported by the imminent possibility of collision between Act 144 and the NGA. See
Northern Natural Gas Co.
v.
State Corporation Comm’n of Kansas,
When a state regulation “affect[s] the ability of [FERC] to regulate comprehensively . . . the transportation and sale of natural gas, and to achieve the uniformity of regulation which was an objective of the Natural Gas Act” or presents the “prospect of interference with the federal regulatory power,” then the state law may be pre-empted even though “collision between the state and federal regulation may not be an inevitable consequence.”
Northern Natural Gas Co.,
We therefore conclude that the MPSC regulation of respondents through Act 144 impinges on a field that the federal regulatory scheme has occupied and, consequently, that Act 144 is pre-empted. 13
*311 IV
Because we have concluded that Act 144 is pre-empted by the NGA, we need not decide whether, absent federal occupation. of the field, Act 144 violates the Commerce Clause. See
Transcontinental Gas Pipe Line Corp.
v.
State Oil and Gas Bd. of Mississippi,
The judgment of the Court of Appeals is affirmed.
It is so ordered.
Notes
“ ‘Natural-gas company’ means [an individual or a corporation] engaged in the transportation of natural gas in interstate commerce, or the sale in interstate commerce of such gas for resale.” §§ 2(6) and (1) of the NGA, 15 U. S. C. §§ 717a(6) and (1).
Petitioners argued below that Storage was not a natural gas company within the meaning of the NGA, contending that the storage of gas constitutes neither the transportation nor the sale of gas in interstate commerce. Both courts below rejected this argument, see
By the NGA, “Congress undertook to establish federal regulation over most of the wholesale transactions of electric and gas utilities engaged in interstate commerce, and created the Federal Power Commission . . . (now the Federal Energy Regulatory Commission) ... to carry out that task.”

v.
Arkansas Public Serv. Comm’n,
Act 144 provides in relevant part:
“Sec. 1. (1) . . . [A] corporation, association, or individual exercising or claiming the right to carry or transport natural gas for public use, directly or indirectly, ... by or through a pipeline or engaged in the business of piping or transporting natural gas for public use, directly or indirectly, or engaged in the business of purchasing natural gas for distribution may issue stocks, bonds, notes, or other evidences of indebtedness payable at periods of more than 12 months after the date of issuance, if necessary for the acquisition of property, the construction, completion, extension, or improvement of facilities or for the improvement or maintenance of service or for the discharge or lawful refunding of obligations and may issue stock to represent accumulated earnings invested in capital assets and not previously capitalized, if the Michigan public service commission issues an order authorizing the issue and the amount of the issue, and states that in the opinion of the commission the use of the capital or property to be acquired to be secured by the issue of the stock, bonds, notes, or other evidences of indebtedness, is reasonably required for the purposes of the person, corporation, or association, or that the issue of the stock fairly represents accumulated and undistributed earnings invested in capital assets and not previously capitalized. Approval of securities does not presume that the projects to be constructed or property to be acquired will be included in the company’s rate base.
“(2) A person, corporation, or association desiring authority to issue stocks, bonds, notes, or other evidences of indebtedness shall make written application to the commission in the form as the commission requires. After receiving the application, the commission, for the purpose of determining whether the commission should grant the authority, may make an *297 inquiry or investigation, hold hearings, and examine witnesses^ books, papers, documents, or contracts the commission considers of importance in enabling it to reach a determination. An interested person, including municipalities and organizations whose membership consists of a substantial number of ratepayers within the service area of the utility, shall have the right to intervene as provided in the rules of the commission ....
“(3) If from the application filed and other information obtained from the investigation authorized in this act the commission is satisfied that the funds derived from the issue of stocks, bonds, or notes are to be applied to lawful purposes and that the issue and amount is essential to the successful carrying out of the purposes, or that the issue of the stock fairly represents accumulated and undistributed earnings invested in capital assets and not previously capitalized, the commission shall grant authority to make the issue. In granting the authority, the commission may impose as a condition of the grant reasonable terms and conditions that the commission considers proper.
“(4) A person, corporation, or association may issue notes for lawful purposes, payable at periods of not more than 24 months, without authority from the commission; but the notes shall not in whole or in part, be refunded by an issue of stock or bonds or by an evidence of indebtedness running for more than 12 months without the consent of the commission.
“(5) This act shall apply to stock, shares, bonds, or notes issued to or taken by the incorporators or their agents, assigns, or trustees of a corporation or association in the first instance, and shall also apply to stock, bonds, or notes issued to or taken by the stockholders of the corporation or association, their agents, assigns, or trustees, after the first instance.
“(8) This act shall not apply to a person, corporation, or association which is engaged in the business of carrying, transporting, piping, purchasing for distribution, or selling natural gas into this state, which derives less than 5% of its consolidated gross revenues from all of its operations from natural gas operations in this state, and which does not offer residential natural gas service to the general public under rules promulgated by the Michigan public service commission.” Mich. Comp. Laws Ann. §460.301 (Supp. 1987).
Subsection (8) of Act 144 provides, however, see n. 3, supra, that the Michigan statute does not apply to a natural gas company that “derives less than 5% of its consolidated gross revenues from all of its operations from natural gas operations in [Michigan].”
The parties agreed that the District Court should decide the case on the basis of a stipulation of facts, an appendix thereto, respondents’ answers to three sets of interrogatories, and respondents’ replies to two sets of requests for admissions.
The Natural Gas Policy Act of 1978 (NGPA), 92 Stat. 3351, 15 U. S. C. § 3301
et seq.,
did not compromise the comprehensive nature of federal regulatory authority over interstate gas transactions.

See, e. g., as introduced, H. R. 5306 and S. 2746, 81st Cong., 1st Sess. (1949); S. 1880, 84th Cong., 1st Sess., § 3 (1955).
It is perhaps worthy of note that the purported purposes of Act 144, as applied to respondents, appear highly artificial at best. Storage does not *308 serve any Michigan consumers. Thus, it is hard to see what effect regulation of Storage could have on the supply of gas at reasonable rates to Michigan consumers. As to investors, since respondents issue their securities on international and national financial markets, Michigan investors are involved with these issuances only to the extent they operate and invest through these markets. Thus, even petitioners must concede that Michigan investors probably will never own more than a small percentage of respondents’ outstanding securities.
Of course, one area FERC does not exclusively control is “securities regulation” in the traditional sense of the term, i. e., protection of investors from fraudulent or deceptive issuances. Michigan has an interest in guarding against the sale of such securities in Michigan. To this end, Michigan, like many other States, has a “blue sky” law that governs the registration and sale of securities sold within the State. See Mich. Comp. Laws Ann. § 451.701 et seq. (1967 and Supp. 1987). While such traditional “securities regulation” is not FERC’s direct concern, Act 144 is not that kind of regulation. Act 144 applies only to utilities and is not limited to securities sold within Michigan.
Normally, regulations do not pre-empt state authority unless they declare their intent to do so with “some specificity.” See
