MEMORANDUM OPINION
This matter is before the Court on the parties’ cross-motions for summary judgment. The underlying action involves a “reverse FOIA” claim filed by plaintiff Environmental Technology, Inc. (“ETI”), which seeks a permanent injunction preventing defendant United States Environmental Protection Agency (“EPA”) from disclosing, pursuant to the Freedom of Information Act, certain information regarding a contract awarded to ETI by the EPA.
For the reasons discussed below, defendant EPA’s motion for summary judgment will be DENIED, plaintiff ETI’s motion for summary judgment will be GRANTED, and a permanent injunction will be ENTERED against defendant EPA.
I. Factual Background
The facts of this case, which are not in dispute, are as follows:
Plaintiff ETI, a company which provides environmental cleanup services, was awarded a contract by Region III of the EPA on January 31, 1992, for certain environmental cleanup services and equipment. After the contract was awarded, the EPA received requests under the Freedom of Information Act from two competitors of ETI, OHM Corporation and Unidyne Corporation, seeking copies of the contract and certain related information. OHM sought “a copy of [the] contract, including all rates,” while Unidyne sought copies of the contract, ETI’s technical and cost proposal, the business clearance for the procurement and related documents, and a list of all bidders on the contract and their final bid prices.
The FOIA requests were processed by Marie Murphy, a contract officer for EPA Region III. She reviewed the documents requested, and notified ETI that the information had been requested under the FOIA. On April 2, April 3 and April 8, 1992, ETI sent Ms. Murphy letters setting forth its position concerning the confidentiality of the *1228information requested. After reviewing ETI’s arguments, Ms. Murphy concluded that ETI’s proposal itself was confidential. She also determined, however, that the information contained in attachments B-2 through B-6 of the contract was “unit price information,” and therefore not entitled to confidential treatment.1
Pursuant to EPA regulations (see 40 C.F.R. §§ 2.205(f)(l)(i) and (f)(2)), Ms. Murphy sent ETI a letter on May 6,1992, notifying it of her conclusion with respect to attachment B-6.2 The letter informed ETI that the information would be released to the public within 10 working days unless EPA received notice of the filing of a federal court action to obtain judicial review of Ms. Murphy’s decision and to obtain injunctive relief.
ETI responded by letter dated May 15, 1992, proposing certain restrictions with respect to the release of the contract information. In a May 27, 1992, letter, EPA responded that it could not abide by plaintiffs proposed restrictions, and informed plaintiff that the information would be released on May 29 unless EPA’s counsel received notice by that date that a federal court action had been filed. Plaintiff filed the present action on May 29, 1992.
Plaintiff ETI asserts that it will suffer competitive harm if the EPA releases the information. In moving for summary judgment, ETI contends that FOIA Exemption 4, precluding disclosure of “trade secrets and commercial or financial information obtained from a person and privileged and confidential,” is applicable. See 5 U.S.C. § 552(b)(4).
Both parties agree that the information at issue is “commercial or financial information” and that it was “obtained from a person” outside government. Thus, the Court must focus on whether the information, for purposes of Exemption 4, is “privileged and confidential.”
II. Discussion
A suit challenging a federal agency’s decision to disclose records under the Freedom of Information Act (a “reverse FOIA suit”) is cognizable only as an Administrative Procedure Act suit — the FOIA itself does not create a right of action. Chrysler Corp. v. Brown, 441 U.S. 281, 317-18, 99 S.Ct. 1705, 1725-26, 60 L.Ed.2d 208 (1979). Under the APA, an agency decision will be held unlawful only if it is arbitrary, capricious, or not otherwise in accordance with the law. 5 U.S.C. § 706(2)(A).
In Chrysler, the Supreme Court found that the Trade Secrets Act, 18 U.S.C. § 1905, bars disclosure of information that falls within Exemption 4 of the FOIA, and that a decision to disclose such information therefore would not be in accordance with the law. Chrysler, 441 U.S. at 318, 99 S.Ct. at 1726; Acumenics Research & Technology v. United States Dep’t of Justice, 843 F.2d 800, 804 (4th Cir.1988). Thus, if the information at issue in this case is “privileged and confidential” and falls within Exemption 4, it should not be released.
In Critical Mass Energy Project v. Nuclear Regulatory Commission, 975 F.2d 871 (D.C.Cir.1992) (en bane), the D.C. Circuit redefined the concept of “confidential” information in situations involving information provided to the government on a voluntary basis. Such information is “confidential,” the court held, “if it is of a kind that the provider would not customarily release to the public.” Id. at 880.
In adopting this rule, the D.C. Circuit limited the application of the test it previously *1229established in National Parks & Conservation Ass’n v. Morton, 498 F.2d 765 (D.C.Cir. 1974), to those situations in which an FOIA request involves financial or commercial information that a person was obligated to furnish to the government. Critical Mass, 975 F.2d at 880.3
While the Fourth Circuit, in Acumenics, adopted the National Parks test, see 843 F.2d at 807, the circuit court has not yet been presented with an opportunity to consider the D.C. Circuit’s recent refinement of the test. As this Court finds the D.C. Circuit’s reasoning in Critical Mass to be persuasive, it will employ that court’s distinction between information voluntarily provided to the government and information provided pursuant to an obligation.
Applying the Critical Mass test to the facts stated above, it is clear that the information at issue was submitted voluntarily by ETI in response to the EPA’s request for bids. It is also readily apparent that the information is of a kind that ETI would not customarily share with its competitors or with the general public. Accordingly, the information falls within Exemption 4, and should not be released.4
III. Conclusions
For the reasons set forth above, defendant EPA’s motion for summary judgment is hereby DENIED, plaintiff ETI’s motion for summary judgment is GRANTED, and defendant EPA is ENJOINED from releasing the information at issue pursuant to the Freedom of Information Act.
An appropriate Order will issue.
And it is SO ORDERED.
