Matala is an underground coal employee at Consolidation Coal Company’s (Consolidation) Blaeksville No. 2 mine in Mononga-lia County, West Virginia. Prior to March 1, 1975, Matala was employed as a continuous mine operator. On or about March 1, 1975, he was diagnosed as having symptoms of pneumoconiosis (black lung). He thus exercised his right granted by section 203(b)(2) of title II of the Federal Coal Mine Health & Safety Act of 1969 (the Act)1 to transfer to a less dusty area of the mine. Any miner who exercises his option to transfer is guaranteed by section 203(b)(3) compensation for his new work “at not less than the regular rate of pay received by him immediately prior to his transfer.” 30 U.S.C. § 843(b)(3).
After his transfer, Matala was classified as a general inside laborer, a classification having a lower daily base rate than that of his old classification as a continuous mine operator. Matala, however, was paid the same daily base rate after his transfer that he received immediately prior to his transfer. He also received periodic cost of living increases granted to all coal miners.
In a complaint filed with the Department of Labor pursuant to 30 U.S.C. § 938,2 Mat-ala contended that after he transferred, he was entitled under section 203(b)(3) not only to the same daily base pay that he received in his prior job classification, bút also to all wage increases subsequently granted to miners classified as continuous mine operators during the term of the wage agreement that sets the pay scales for each job classification.3 He claimed that Consolidation discriminated against him in violation of 30 U.S.C. § 938(a) when it failed to grant him such increases.4
*429The Secretary of Labor (Secretary) interpreted “regular rate of pay” in section 203(b)(3) to mean the dollar amount that Matala received immediately prior to transferring. The Secretary found that Matala’s employer, Consolidation, had paid Matala the same amount after his transfer that he had received immediately prior to transferring. He concluded that Consolidation had not discriminated against Matala by reason of his having been diagnosed as having pneumoconiosis. Thus, Matala’s complaint was dismissed.
Matala then filed a petition in district court for review of the Secretary’s order. The district court concluded that the Secretary’s interpretation of section 203(b)(3) was erroneous. It, therefore, granted Mat-ala’s motion for summary judgment against the Secretary and Consolidation, reversing the decision of the Secretary. Both the Secretary and Consolidation appeal the district court’s decision. We reverse.
I.
In this case we must decide whether section 203(b)(3) of the Act guarantees the transferred miner only the amount that he received immediately prior to his transfer or whether it requires the employer to continue to pay a transferred employee at his pre-transfer classification rate. If we adopt this latter construction, a transferred employee would continue to receive any pay increases granted to those in his pre-transfer classification subsequent to his transfer.
When we are faced with a question of statutory interpretation, our starting point for discerning congressional intent is the language of the statute itself. State Water Control Board v. Train, 559 F.2d 921, 924-25 n.20 (4th Cir. 1977). Congress is presumed to have used words according to their ordinary meaning unless a different use is clearly indicated. United States v. Snider, 502 F.2d 645 (4th Cir. 1974). In examining section 203(b)(3), we find the language contained therein to be unambiguous. Accord, Higgins v. Marshall, 584 F.2d 1035 (D.C.Cir.1978), cert. denied, 441 U.S. 931, 99 S.Ct. 2051, 60 L.Ed.2d 659 (1979). The meaning of section 203(b)(3) is clear on its face; it provides that a miner who transfers because of pneumoconiosis “shall receive compensation for such work at not less than the regular rate of pay received by him immediately prior to his transfer.” (emphasis added). The ordinary meaning of “rate” is dollar amount. See Higgins v. Marshall, 584 F.2d 1035 (D.C.Cir. 1978), cert. denied, 441 U.S. 931, 99 S.Ct. 2051, 60 L.Ed.2d 659 (1979). Furthermore, “regular rate of pay” must not be read alone but must be construed with the rest of section 203(b)(3). See United States v. Snider, 502 F.2d 645, 652 (4th Cir. 1974). In the statutory context of section 203(b)(3), the plain meaning of “rate” is confirmed by the modifying phrase “received by him immediately prior to his transfer.” If “rate” were construed as referring to classification rate, then “received by him” would have no meaning, thereby violating a basic canon of statutory construction that all words in a statute are to be given effect. Id.
Matala has urged upon us a construction that is at odds with the plain meaning of section 203(b)(3). He contends that “regular rate of pay” means the classification rate. In support of his position, he cites two passages in the legislative history. He first asserts that the conferees intended *430that the Act be construed liberally when improved health or safety to miners will result. H.R.Rep.No.761, 91st Cong., 1st Sess. 63 (1969), U.S.Code Cong. & Admin. News 1969, p. 2503. He also argues that our interpretation is contrary to Congress’ intent that those who transfer should “suffer no loss in compensation.” S.Rep.No.411, 91st Cong., 1st Sess. 50 (1969). Matala contends that if “regular rate of pay” is interpreted to mean merely dollar amount, then, although the miner who transfers may not necessarily suffer any loss at the moment of transfer, he may suffer substantial losses shortly after transferring if those persons in his pre-transfer classification are granted subsequent increases.5
While we sympathize with Matala’s position, we do not agree with it. The plain meaning of a statute should be rejected only if there is substantial, unambiguous evidence supporting a contrary interpretation. State Water Control Board v. Train, 559 F.2d 921, 924-25 n.20 (4th Cir. 1977). We find Matala’s references to the legislative history to be very general, and we are not persuaded that the broad passages he cites should be deemed to support clearly and conclusively a contrary interpretation. Our plain meaning construction does not do violence to the intent of Congress that a miner transferring because of black lung should not lose money because of his transfer. Under our interpretation a miner who exercises his statutory right of transfer would receive the same dollar amount that he received immediately prior to his transfer, thus suffering no loss of pay upon transfer.
It appears that Matala has sought to create an ambiguity in section 203(b)(3) by his citations to the legislative history. We look to the legislative history in construing a statute only if the meaning of a statute is unclear. See United States v. Oregon, 366 U.S. 643, 648, 81 S.Ct. 1278, 1281, 6 L.Ed.2d 575 (1961). The legislative history should never be used to create doubt if the language of a statute is plain on its face. Railroad Commission of Wisconsin v. Chicago, Burlington and Quincy Railroad Co., 257 U.S. 563, 589, 42 S.Ct. 232, 237, 66 L.Ed. 371 (1922). Because we find the language of section 203(b)(3) to be clear and unambiguous, we find no need to resort to the legislative history.6
We hold that, after transferring, Matala was entitled to receive no less than the dollar amount that he received immediately prior to his transfer. Thus, because Matala received $55.00 per day plus a $.07 per hour cost-of-living add-on prior to his transfer, he was entitled to receive no less than $55.00 per day plus $.07 per hour after his transfer.7 Accordingly, we reverse the judgment of the district court and remand this case to the district court for entry of an order consistent with this opinion.
REVERSED AND REMANDED.
. Section 203(b)(2) provides in relevant part: [A]ny miner who ... shows evidence of the development of pneumoconiosis shall be afforded the option of transferring from his position to another position in any area of the mine ... where the concentration of res-pirable dust in the mine atmosphere is not more than 1.0 milligrams of dust per cubic meter of air. 30 U.S.C. § 843(b)(2).
. This section prohibits an operator from discriminating against “any miner employed by him by reason of the fact that such miner is suffering from pneumoconiosis.” 30 U.S.C. § 938(a). It sets forth the procedure for a miner to follow if he believes that discrimination has occurred. 30 U.S.C. § 938(b).
. At the time of Matala’s transfer, the National Bituminous Coal Wage Agreement of 1974 governed the hours, wages, job classifications, and other working conditions of the workers at Consolidation’s Blaeksville No. 2 mine. This agreement expired on December 5, 1977. Pursuant to the 1974 agreement, and immediately prior to his transfer, Matala was receiving a base wage of $55.00 per day plus a $.07 per hour cost of living adjustment. From the date of his transfer to the date that the agreement expired, Matala received the following noncumulative add-on cost of living adjustments:

. Even if we were permitted to look to the legislative history, we find nothing contained therein that would resolve the alleged ambiguity. Certainly there is evidence that section 203(b)(3) should be construed broadly, but there is no evidence that Congress intended “regular rate of pay” to mean classification rate. In fact, Congress had the opportunity to change section 203(b)(3), if it so desired, to comport with the meaning that Matala contends is proper. When Congress was amending various titles of the Act in 1977, Arnold Miller, President of the United Mine Workers of America, submitted a prepared statement to both the Senate and House subcommittees, advising them that coal mine operators were interpreting section 203(b)(3) as requiring them to pay transferring miners only the dollar amount that they received immediately prior to transferring. Miller suggested that the wording of section 203(b)(3) be changed to make it clear that Congress intended for the transferring miners to continue to receive any increases they would have received had they remained in their former position. Congress did not adopt Miller’s suggestions in 1977 when it made major changes in titles I and V of the Act, and minor amendments to title II (which includes section 203(b)(3)), III, and IV.
. It appears that from December 6, 1976 to January 31, 1977, Matala was paid only $55.00 per day and that from February 1, 1977 to April 30, 1977, he was paid only $55.00 per day plus $.04 per hour. See note 3, supra. Because his pay during these two periods was less than the $55.00 per day plus $.07 per hour that he received immediately prior to his transfer, he is entitled to back pay for these two periods.
