Opinion for the Court filed by Circuit Judge WILKEY.
Petitioner is the operator of the Zeigler No. 9 Mine near Madisonville, Kentucky. The purely legal issues swirl about the enforceability of the mine’s ventilation plan, which was adopted by the operator after approval and subject to periodic review by the respondent Secretary pursuant to the Federal Coal Mine Health and Safety Act.
I.
Setting the stage for- controversy, petitioner’s ventilation plan was apparently amended at the agency’s suggestion on 9 November 1973. A requirement was added, to be effective 1 January 1974, that “wood used in stoppings, doors, and other ventilation controls” be treated with fire-retardant material.
On 25 January 1974 a Mine Enforcement Safety Administration (MESA) inspector issued a notice of violation pursuant to § 104(b), charging that three doors in the mine had not been so treated. Six days were given to abate the condition, although the total time required, once fire-retardant paint was procured, was only about four man-hours per door. On 31 January the condition had not been completely abated, and an additional day was given to comply. Again on the morning of 1 February a further extension was given until 1:45 p. m. When full compliance had not been achieved by that time, the inspector issued the order of withdrawal here under attack. Compliance was achieved and the mine was reopened at 5:45 p. m. the same day.
Petitioner sought review of the inspector’s withdrawal order, pursuant to § 105(a) of the Act.
On this appeal of the Board’s order of affirmance, the material facts are not in dispute. Rather, the question posed is one of law, which has far-reaching importance for the future effectiveness of the statute. For, while numerous standards, regulations, and plans
II.
The Federal Coal Mine Health and Safety Act of 1969 was enacted in the wake of the 1968 Farmington, West Virginia, mine disaster, in order “to protect the health and safety of coal miners, and to combat the steady toll of life, limb, and lung, which terrorizes so many unfortunate families.”
The part of the Act aimed at assuring the maintenance within mines of appropriate health and safety conditions, is built around the concept of the mandatory standard. The legislative history reveals two competing concerns in the minds of persons affected by the legislation, and the mandatory standard concept was adopted as a way of reconciling the apparent inconsistency. On the one hand, Congress’ inability to respond rapidly to changing conditions of knowledge and technology made it desirable to create a power of amendment at the agency level.
The mandatory standard concept evolved to deal with this dilemma combines a comprehensive set of “interim” mandatory standards, promulgated by Congress,
In addition to these interim and improved mandatory standards, the Act also provides for several types of promulgations that are not bound by the procedures of § 101, A substantial number of the interim standards impose requirements whose actual terms are to be set in part by action of the Secretary.
The final important element of the statutory scheme is the enforcement machinery by which the mine operators are compelled to obey the health and safety requirements otherwise promulgated. The statute establishes three kinds of enforcement remedies —withdrawal, civil fine, and criminal penalties — and sets up procedures governing the application of each. It provides for remedial actions of increasing severity, as the nature of the conduct being redressed grows more serious. But except insofar as § 104(a) allows for immediate withdrawal in any instance of imminent danger, virtually all
HI.
Our first inclination is to construe literal
A strict literal reading of the statute’s definition provision would render all of the above regulations merely advisory, without enforceable weight. Many of the interim standards would be left without enforceable essential components, which were left by the statute itself to future determination by the Secretary. Numerous others would be rendered vague and uncertain by virtue of the holding that their interpretive regulations could not be enforced.
On the whole, it appears to us that this result would greatly impair the statute’s effectiveness as a tool for bringing about improvements in mine health and safety conditions. Congress could hardly have intended this result. The overall remedial purposes of the Act suggest to us that its language should be given a more liberal construction in favor of the broad goals being pursued.
Finding little guidance on the face of the statute or in the legislative history,
Both parties on appeal make at least implicit reference to the general proposition that a statute should not be construed in such a way as to render certain provisions superfluous or insignificant.
The core of Petitioner’s argument is that the Board’s decision upholding enforcement of a ventilation plan provision flies in the face of the rigorous § 101 procedures to be followed in the promulgation of mandatory standards.
Insofar as plan requirements, appearing nowhere among the interim or § 101 mandatory standards, are found enforceable under § 104(b) and the other coercive sections, the statute does, in a sense, offer a way around the stringent requirements attendant to mandatory standard promulgation. As we have noted, these stringent requirements were the product of legislative battle and compromise. But Congress apparently did not realize that a host of promulgations which it expected the Secretary to make would be left unenforceable under the literal language of the § 3(1) mandatory standard definition. Because we read the statute as placing quite narrow limits on the subject matter properly treated in ventilation plans, and because the operator has a mechanism available to assure that plans do not exceed these limits, we conclude that enforcing duly adopted ventilation plans poses no threat to the continued vitality of § 101.
The statute makes clear that the ventilation plan is not formulated by the Secretary, but is “adopted by the operator.”
The agency’s recourse to such a refusal to adopt a particular plan appears to be invocation of the civil and criminal penalties of § 109, which require an opportunity for public hearing and, ultimately, appeal to the courts.
The language of § 303(o) explicitly limits the plan at issue before us to the “ventilation system and methane and dust control.” While these words might be stretched to encompass requirements pertaining indirectly but not primarily to ventilation, there would also appear to be a wide range of matters which could not properly be touched upon, under any logical reading of the section.' Attempted inclusion of such matters could be successfully contested by the operator in an enforcement action brought by the Secretary.
A less apparent but more significant restriction on the Secretary’s power to use the ventilation plan as a vehicle for avoiding more stringent procedural requirements, arises from the plan provision’s obvious purpose to deal with unique conditions peculiar to each mine. Section 303(o) specifically states that the plan is to be “suitable to the conditions and the mining system of the coal mine. . . . ”
Thus an operator might contest an action seeking to compel adoption of a plan, on the ground that it contained terms relating not to the particular circumstances of his mine, but rather imposed requirements of a general nature which should more properly have been formulated as a mandatory standard, under the provisions of § 101. This would appear to render all but inconsequential the actual circumvention of § 101 resulting from the enforceability of ventilation plans. For insofar as those plans are limited to conditions and requirements made necessary by peculiar circumstances of individual mines, they will not infringe on subject matter which could have been readily dealt with in mandatory standards of universal application.
Having rejected as largely without merit Petitioner’s argument that enforcement of ventilation plan provisions would impair the effectiveness of § 101 procedures concerning mandatory standards, we move now to a parallel contention raised by the Government. The Interior Department appears to argue that a decision finding the plan provisions unenforceable would render meaningless the § 303(o) requirement that a ventilation plan be adopted, because “an unimplemented, approved plan clearly is equivalent to no plan at all.”
Certainly, too, however, a finding of unenforceability would render the statute less effectual as a tool for assuring safe operating conditions. The question we must ask is not whether plan provisions must be enforceable to have meaning, for they clearly need not; it is rather whether they must be enforceable to have as much meaning as the framers of the statute intended. We are moved by the circumstances of the Act’s adoption and its manifest purposes, by the consistent interpretations of the IBMA, and by the continuing need for stringent measures to improve mine safety, to conclude that properly adopted ventilation plan provisions must be regarded as generally enforceable under the statute.
The Federal Coal Mine Health and Safety Act was enacted out of great Congressional concern to improve the conditions in which thousands of Americans must spend their work days. Along with the statute’s own language
Applying the rubric of statutory construction which commands that ambiguous provisions should be construed with ref
This conclusion of enforceability also finds consistent support in the interpretations of the IBMA, the agency assigned to implement the statute. That Board, in the case now before us and elsewhere, has made clear its view that terms of plans duly adopted pursuant to the statute are enforceable as mandatory standards.
Finally, we would be less than candid were we not to note our awareness of the great continuing hazards which coal miners still face, more than six years after enactment of the statute. Even as this opinion is prepared, Congressional hearings are taking place to inquire into the most recent mine disaster and to consider possible amendments to the statute tightening its standards and enforcement provisions.
IV.
For the above reasons, we conclude that requirements of duly adopted ventilation plans

. 30 U.S.C. § 814(b) (1970).
Section 104(b) allows the Secretary to order withdrawal after notice and reasonable opportunity for abatement, where “there has been a violation of any mandatory health or safety standard” which poses no imminent danger to health or safety. It operates in conjunction with two other provisions of § 104. Section 104(a) authorizes immediate withdrawal without opportunity for abatement, wherever imminent danger exists. Section 104(c) authorizes withdrawal in the face of “unwarrantable failure ... to comply with” a mandatory health or safety standard, which “could significantly and substantially contribute to the cause and effect of a mine safety or health hazard . ,” where notice of a violation similarly describable has been given within the past ninety days.
. Only § 104(a) and the willful violation provisions of §§ 109(b) and (c), 30 U.S.C. §§ 814(a), 819(b) and (c) (1970), among the enforcement provisions of the Act, are not strictly limited by their language to mandatory standard violations. Even these sections seem to require as their predicate an initial finding of imminent danger under § 104(a), in order to be applicable in the absence of a mandatory standard violation. Thus they do not provide a generally available avenue of enforcement for any promulgations under the Act not properly classified as mandatory standards.

The plan shall show the type and location of mechanical ventilation equipment installed and operated in the mine, such additional or improved equipment as the Secretary may require, the quantity and velocity of air reaching each working face, and such other information as the Secretary may require. Such plan shall be reviewed by the operator and the Secretary at least every six months.

.The statute’s preamble summarizes the concerns which gave rise to the legislation:
Congress declares that—
(a) the first priority and concern of all in the coal mining industry must be the health and safety of its most precious resource — the miner;
(b) deaths and serious injuries from unsafe and unhealthful conditions and practices in the coal mines cause grief and suffering to the miners and to their families;
(c) there is an urgent need to provide more effective means and measures for improving the working conditions and practices in the Nation’s coal mines in order to prevent death and serious physical harm, and in order to prevent occupational diseases originating in such mines;
(d) the existence of unsafe and unhealthful conditions and practices in the Nation’s coal mines is a serious impediment to the future growth of the coal mining industry and cannot be tolerated;
(e) the operators of such mines with the assistance of the miners have the primary responsibility to prevent the existence of such conditions and practices in such mines;
(f) the disruption of production and the loss of income to operators and miners as a result of coal mine accidents or occupationally caused diseases unduly impedes and burdens commerce; and
(g)it is the purpose of this chapter (1) to establish interim mandatory health and safety standards and to direct the Secretary of Health, Education, and Welfare and the Secretary of the Interior to develop and promulgate improved mandatory health or safety standards to protect the health and safety of the Nation’s coal mines; (2) to require that each operator of a coal mine and every miner in such mine comply with such standards; (3) to cooperate with, and provide assistance to, the States in the development and enforcement of effective State coal mine health and safety programs; and (4) to improve and expand, in cooperation with the States and the coal mining industry, research and development and training programs aimed at preventing coal mine accidents and occupationally caused diseases in the industry.

. While we are not presented with a problem involving any of the other types of plans which the operator is to promulgate under the statute, much of the reasoning presented here seems to us applicable in many of those instances as well. Emergency plans appear to pose something of a special case, in that to a great extent they remain unimplemented until the contingency arises.
. See notes 40, 41, 42 and text accompanying, supra.

. Since the plan provision at issue is not alleged to be unreasonable or overly burdensome, and there is no question that it has been adopted by the operator, we see no need to inquire as to whether it is the type of term which the Secretary could compel an operator to adopt. While the court has solicited material from the Interior Division of Mine Health and Safety relating to whether the fire-retardant door requirement relates to unique or specific mine conditions, our decision rests in no part upon that information. We make no decision whether operators can be compelled to incorporate such a provision in future plans.
We also find it unnecessary to decide whether ventilation plans must be promulgated pursuant to the rulemaking procedures of the APA, 5 U.S.C. 553 (1970), since Petitioner nowhere argues non-compliance with those provisions as a reason for reversing the Board’s decision.
