McDONALD, J.

The point of contention in this case is whether a local board of education has acted within its statutory authority. For some years, the Board of Education of Baltimore County ("Board of Education"), the Appellee, has belonged to a governmental group purchasing consortium — a sort of warehouse club for government entities — which competitively bid a roofing services contract on behalf of its members. The Board of Education has relied on that contract to fulfill its needs for roofing repair services. Appellant Building Materials Corporation of America, a nationwide manufacturer of roofing materials that does business under the name GAF Materials Corporation ("GAF"), questions the Board of Education's authority for that practice under the pertinent statutes.

A local board of education derives its powers and responsibilities from the State education law. One section of that law requires a local school system to conduct a competitive bidding process itself for procurement but explicitly authorizes the use of intergovernmental purchasing cooperatives for the purchase of "goods and commodities" — a phrase that ordinarily would not be understood to encompass construction services. In other parts of the education law, however, the Legislature has delegated substantial authority to the Board of Public Works and the Interagency Committee on School Construction to direct and oversee local school construction financed with State funds. Those agencies have endorsed the use of intergovernmental cooperatives in regulation and have specifically approved its use by the Board of Education for the acquisition of roofing services.

The Circuit Court for Baltimore County granted summary judgment in favor of the Board of Education. We affirm that judgment. When viewed in the context of the entire education law and regulations promulgated under that law, the competitive bidding statute does not bar the Board of Education from using its membership in an intergovernmental purchasing consortium for the procurement of roofing repair services.

Background

Public School Governance and Funding

In compliance with the constitutional directive to establish a "thorough and efficient" system of public education,1 the General Assembly has created a structure for the operation and maintenance of public schools that weaves together State and local responsibilities. Local boards of education, such as the Appellee in this case, operate school systems in each county, subject to oversight by the State Board of Education. Maryland Code, Education Article ("ED"), §§ 2-205, 4-101. Despite their local focus, county boards of education are State agencies that are funded in part by the State and in part by their respective counties. Chesapeake Charter, Inc. v. Anne Arundel County Board of Education, 358 Md. 129, 136, 747 A.2d 625 (2000); ED § 5-202 ("foundation program" for financing local public schools with a combination of State, local, and federal funds). Similarly, while public school construction is very much a local affair, it is subsidized and supervised to a significant degree by the State. ED § 5-301 et seq.

Procurement by Local School Boards

General Requirement for Competitive Bidding — ED § 5-112

While local school boards are formally State agencies and receive a substantial proportion of their funding from the State, they are not subject to the State's general procurement law. Chesapeake Charter, supra. Other State statutes, however, control procurement by a local board. Under ED § 5-112, a local board must ordinarily follow competitive bidding procedures when procuring buildings, improvements, supplies, or equipment costing more than $25,000.2 The statute has an exception to that requirement for "contracts for goods or commodities that are awarded by ... intergovernmental purchasing organizations if the lead agency for the contract follows public bidding procedures." ED § 5-112(a)(3) (emphasis added).

Oversight of School Construction by Board of Public Works

In regards to the construction of a particular type of building3 — a school — the State Board of Public Works ("BPW")4 has a preeminent role. The BPW determines which school construction projects receive State funding. ED § 5-301(c); COMAR 23.03.03.03F. If a project receives State funding, it is subject to supervision and control by the BPW. Beka Industries, Inc. v. Board of Education, 419 Md. 194, 205, 18 A.3d 890 (2011); Chesapeake Charter, 358 Md. at 140 n. 5, 747 A.2d 625. In particular, the Legislature has directed the BPW to "adopt regulations for the administration of programs [of public school construction and capital improvements]" subsidized by State funds. ED § 5-301(d)(1). Pertinent to this controversy, those regulations:

ED § 5-301(d)(2); see also ED § 5-301(b) (BPW to adopt regulations on eligible and ineligible costs); § 5-301(b-1) (BPW to adopt regulations on indoor air quality for classrooms); § 4-126(c), (g) (BPW to adopt regulations governing alternative financing arrangements for school construction). In adopting regulations, the BPW is to provide for the "maximum exercise of initiative" by county school systems to ensure that school construction meets the needs of the community and is a prudent expenditure of State funds. ED § 5-301(d)(4).

County school boards are subject to the school construction regulations adopted by the BPW. ED § 5-301(g)(1). The Legislature has directed that, in the event of a conflict between those regulations and the "authority, responsibilities, powers and duties" of a county school board (or those of certain other State and local agencies), the BPW's regulations prevail. ED § 5-301(g)(2).5 Moreover, the Legislature has expressly made State funding of local school construction contingent on compliance with the BPW's regulations. ED § 5-301(h).

Interagency Committee on School Construction

To assist the BPW in its duties related to school construction and to administer the State's public school construction program on behalf of the BPW, the Legislature has created the Interagency Committee on School Construction ("IAC").6 ED § 5-302. The BPW is authorized to delegate its administrative and budget authority with respect to school construction to the IAC as "necessary and appropriate." ED § 5-302(a)(5). The Legislature has also specifically directed the BPW to adopt regulations as recommended by the IAC. See ED § 4-126(g) (regulations concerning alternative financing arrangements); ED § 5-301 (regulations concerning planning and procurement of school construction).

Regulations Authorizing "Intergovernmental Cooperative Purchasing"

Participation in intergovernmental cooperative purchasing arrangements, if done well, can yield savings in time and funds devoted to administering a procurement process, as well as result in a more favorable price. See National Association of State Purchasing Officers, Strength in Numbers: An Introduction to Cooperative Procurements, available at <www.naspo. org/documents/Cooperative_Purchasing 0410update.pdf>. In its school construction regulations, the BPW has endorsed the use of intergovernmental cooperative purchasing agreements as an alternative to competitive bidding procedures in certain circumstances. COMAR 23.03.03.03; COMAR 23.03.03.04; COMAR 23.03.03.12. In particular, the regulation concerning procurement methods provides:

COMAR 23.03.03.03 (emphasis added). The regulations further state a preference for the use of the competitive sealed bidding method, but permit the use of other methods under specified circumstances. COMAR 23.03.03.04.7 One of the regulations sets forth the circumstances under which a school system may use intergovernmental cooperative purchasing:

COMAR 23.03.03.12.

Board of Education Roofing Contracts

In 2005, the Board of Education joined the Pennsylvania Education Joint Purchasing Council ("PAEJPC"), an intergovernmental purchasing cooperative that serves more than 300 school systems, colleges, and universities in Pennsylvania, Maryland, and West Virginia. See <www. paejpc.org> (last visited August 9, 2012). PAEJPC offers its members the opportunity to participate in various cooperative purchasing contracts, including a contract for roofing services, that have been developed through a competitive bidding process conducted by the Association of Educational Purchasing Agencies ("AEPA"), another government agency consortium.8 The Board of Education sought and obtained permission from the IAC to purchase roofing services through PAEJPC and AEPA.

In recent years, the successful bidder for the AEPA roofing services contracts has been Weatherproofing Technologies, Inc. ("TREMCO"), a competitor of GAF.9 Since January 2006, the Board of Education, through its membership in the cooperative, has directly awarded TREMCO at least 46 contracts, valued at more than $64 million, for roofing services. Each contract was reviewed and approved by the IAC and funded by the State with the approval of the BPW.

GAF Complaint

This case began when GAF filed a declaratory judgment action in January 2009 against the Board of Education in the Circuit Court for Baltimore County.10 In that action, GAF sought a declaration that the Board of Education's procurement of roofing services failed to comply with the State laws governing local boards of education. GAF alleged that the Board of Education's participation in the AEPA roofing services contract prevented roofers who would use GAF's materials from bidding on the Board's projects.11

The parties filed cross motions for summary judgment. They agreed that there were no material facts in dispute and that the issue to be resolved was a question of law. Following a hearing on the motions, the Circuit Court ruled in favor of the Board of Education in January 2011. GAF noted a timely appeal. It later filed a petition for writ of certiorari, which this Court granted before the matter was heard by the Court of Special Appeals.

Discussion

As is evident, there is no dispute as to the underlying facts and, indeed, this case does not concern any particular procurement.12 Accordingly, our decision turns entirely on how the relevant statutes should be construed — a matter on which we owe no special deference to a circuit court. See, e.g., Nesbit v. GEICO, 382 Md. 65, 72, 854 A.2d 879 (2004).

GAF asserts that the Board of Education, in awarding contracts to TREMCO through the purchasing cooperative, failed to comply with ED § 5-112 by not developing specifications, advertising for bids, and competitively awarding contracts itself. GAF further argues that the exception in ED § 5-112(a)(3) for purchases of "goods and commodities" through purchasing cooperatives does not apply because roofing services are not a "good" or "commodity." It contends that installation of a roof is an "improvement" for which the Board of Education should conduct its own competitive bidding process under ED § 5-112(b). In support of this argument, GAF cites the general State procurement regulations that define "improvement" as "the construction, maintenance, and repair of any building, structure, or other public work now or hereafter constructed or acquired by the State or any State agency." COMAR 21.01.02.01(B)(69).13 Roof repair and replacement, it notes, are "construction, maintenance, and repair" of a building or structure.

The Board of Education disputes GAF's reading of ED § 5-112(a)(3), arguing that roofing repair services could qualify as "goods or commodities." It also points to the authority of the BPW and the IAC over school construction and the green light those agencies have given to its procurement of roofing services through the cooperative.

Plain Meaning in Context

Much has been made of the "plain meaning rule" in the briefs filed by the parties. To be sure, plain meaning is a stalwart first step in our approach to statutory construction.14 A preliminary matter, however, is to identify the statutory or regulatory language to be construed. Consider the well-known phrase "She loves me; she loves me not." If one focuses only on the first clause, the plain meaning appears clear — no need for further exploration. Similarly, if one considers only the second clause, the meaning seems equally clear though quite different. But when the sentence is considered as a whole, there is ambiguity and one must know more than the language alone to discern its meaning. Context and history matter. As this Court has said, "[t]he meaning of the plainest language is controlled by the context in which it appears."15

This Court has previously said that the competitive bidding provision of ED § 5-112 must be viewed in context. In Demory Bros., Inc. v. Board of Public Works, 273 Md. 320, 329 A.2d 674 (1974), a potential contractor opposed the award of a school construction contract on the basis that the competitive bidding statute16 precluded application of the prevailing wage law to the procurement as the bidder who promised compliance with the prevailing wage statute had submitted a higher bid than the bidder who did not. This Court rejected that argument, reasoning that the competitive bidding statute could not be considered in isolation from other statutory provisions relating to school construction. 273 Md. at 327-29, 329 A.2d 674. The Court also held that great weight should be accorded to the BPW's and IAC's interpretation of the public school construction statutes. Id. at 327, 329 A.2d 674. To assess GAF's argument in this case, we must also consider ED § 5-112 in light of those agencies' implementation of the school construction laws.

Legislative History

To place the competitive bidding statute for local board procurement in context, we take a brief detour into the history of the statutes relating to construction of local public schools. That review reveals that the key statutes are the product of three waves of legislative concern that occurred at 30-year intervals.

1930s — Requirement of Locally-Conducted Competitive Bidding

The Legislature first created a competitive bidding requirement for local school construction in 1933 when it enacted the predecessor of ED § 5-112. Chapter 151, § 59B, Laws of Maryland 1933, then codified at Article 77, § 59B.17 It had the usual purposes of preventing favoritism and procuring construction at the lowest cost to the taxpayers. Board of Education v. Allender, 206 Md. 466, 475, 112 A.2d 455 (1955). At that time, school construction was largely a county concern. It was only during the post-World War II boom in school construction that the State first became involved in financing and overseeing public school construction. A. Wilner, The Maryland Board of Public Works: A History (1984) at 95, 103. At that time the Legislature authorized the sale of State bonds to assist the counties with school construction, but required that the financial assistance be contingent on the approval of the BPW. Id. In essence, the State lent its credit to local school systems to help finance local school construction and the BPW simply allocated the use of the State's credit among the various jurisdictions. The BPW was not further involved in the details of procurement or construction.

1970s — BPW Authority to Regulate Local School Construction

This changed in the early 1970s. "In 1971 the State undertook a considerably expanded role in financing local school construction, and the [BPW] was assigned a much more active role in administering the program." Wilner, supra, at 104. The Legislature created the Public School Construction Program and gave the BPW significant responsibility, enacting the predecessors of the statutes now codified at ED § 5-301 et seq. Chapter 624, Laws of Maryland 1971. The BPW was authorized to adopt "rules, regulations, and procedures" on a broad range of activities related to school construction.18 Under that authority the BPW made the controversial decision to create the IAC by regulation19 — a decision later affirmed by the General Assembly in statute. The 1971 legislation also made the "authority, responsibilities, powers, and duties" of all State and local officials involved in school construction subject to the BPW's rules and regulations. This trump card of the BPW currently appears at ED § 5-301(g)(1).

2000s — Extension of BPW Authority to Include Procurement and Financing Methods

Approximately 30 years later, the General Assembly authorized greater reliance on procurement methods other than locally-conducted competitive bidding. In particular, in several instances it endorsed the use of collaborative purchasing methods as an alternative to competitive bidding. It also delegated additional authority to the BPW and IAC with respect to local school construction. And it commissioned a comprehensive review of public school construction in Maryland.

In 2002, the Legislature qualified the competitive bidding requirement in ED § 5-112. It amended that statute to specifically allow local boards of education to participate in intergovernmental purchasing organizations to purchase goods and commodities. Chapters 170, 171, Laws of Maryland 2002, codified at ED 5-112(a)(3).20 The rationale for the amendment was that cooperative purchasing arrangements were likely to result in significant cost savings by reducing advertising and administrative costs and by allowing school systems to take advantage of volume discounts.21

Also in 2002, the Legislature created the Task Force to Study Public School Facilities ("Task Force"). Chapter 288, § 5, Laws of Maryland 2002.22 The Task Force conducted a survey that found that the estimated cost of bringing public schools up to current standards would be approximately $4 billion, of which $1.3 billion represented the cost of repairs and replacement of existing building systems. Final Report of Task Force to Study Public School Facilities (February 2004) at pp. 2-3.

Several of the Task Force's recommendations are relevant to the issue before us. The Task Force noted that many policy decisions had been delegated to the BPW and IAC; it recommended that those policy decisions be expressed in regulations subject to the State Administrative Procedure Act. Task Force Report at pp. 43-46. The Task Force also recommended that local school systems be afforded the flexibility to use alternative financing methods for school construction and "to develop the procurement, contractual, and technical instruments that will meet State and local procurement requirements and bring the project to a successful conclusion." Id. at 41. It also encouraged pooling by school systems in certain types of contracts, recommending that the State "distribute information on existing State purchasing contracts for school furniture, equipment, and services that may be shared by local school systems." Id. at 58.23

The Legislature responded to the Task Force Report by adopting the Public School Facilities Act of 2004. Chapters 306, 307, Laws of Maryland 2004. That legislation authorized local school systems, in a new ED § 4-126, to use "alternative financing methods" for public school construction in accordance with regulations adopted by the BPW, to use alternative methods of project delivery (e.g., construction manager at risk), and to procure school construction by methods other than competitive bidding (e.g., competitive negotiation, acceptance of unsolicited proposals, quality-based selection).24 The Legislature delegated to the BPW the task of defining the circumstances and guidelines for local school systems to exercise their new powers. ED § 4-126(g).

In the same legislation, the General Assembly also expanded the BPW's authority under ED § 5-301 to adopt regulations governing school construction generally to include, among other things, "the award of contracts by school systems." Id., § 2. The BPW exercised its expanded authority to adopt the regulations quoted earlier that authorize local school systems to use intergovernmental cooperative purchasing, including piggybacking and pooling arrangements. COMAR 23.03.03.03; COMAR 23.03.03.12.

Summary

As the above history demonstrates, the competitive bidding requirement of ED § 5-112 is longstanding and predates the significant involvement of the State in subsidizing the construction of local schools. As the State role in financing of public education subsequently increased, the General Assembly has modified the general preference for sealed competitive bidding, particularly in the area of school construction, and delegated substantial authority to the BPW to oversee the financing, procurement, and construction of schools.

These legislative directives to the BPW leave no doubt that the regulations adopted by the BPW are to be treated as "substantive" or "legislative" regulations that are binding on the courts and have the "force of law." Sec'y Dep't of Pub. Safety & Corr. Servs. v. Demby, 390 Md. 580, 604-5, 890 A.2d 310, 325 (2006) (citing Jerri's Ceramic Arts, Inc. v. Consumer Prod. Safety Comm'n, 874 F.2d 205, 207-08 (4th Cir.1989)).25 And the General Assembly has given the BPW the ability to exercise control over all other agencies in the area of public school construction. ED § 5-301(g).

Whether the Board of Education May Use the Cooperative to Purchase Roofing Services

As indicated above, ED § 5-112 — which applies generally to local board procurements — allows local boards to use contracts awarded by intergovernmental purchasing organizations for the procurement of "goods" or "commodities" — terms that are not defined in the education law. Roofing repair services would appear to be outside those terms under the definitions that GAF marshals from a variety of sources.26 To argue to the contrary, the Board of Education relies on the opinion of the executive director of the IAC that the terms "goods" and "commodities" were meant to encompass roof repair.27 But little weight is to be accorded to post-enactment statements of legislative intent, even by the legislators who passed the particular law. See Kelly v. Marylanders for Sports Sanity, Inc., 310 Md. 437, 471 n. 18, 530 A.2d 245 (1987); Sutherland, Statutory Construction § 48.20 (7th ed.2007). Thus, there appears to be little basis for concluding that ED § 5-112(a)(3) authorizes the use of such contracts for roof repair.

The meaning of "good" and "commodity" in ED § 5-112 may seem plain enough even without the aid of a statutory definition, but those two terms are not all we must consider. As noted above, other enactments of the General Assembly which, unlike ED § 5-112,28 are specific to school construction and finance, direct the BPW to adopt legislative regulations concerning the award of school construction contracts by local school systems — regulations that are to provide for the "maximum exercise of initiative" by those systems and that override the "authority, responsibilities, powers and duties" that otherwise govern a local school system. ED § 5-301. In a similar vein, the Legislature has authorized local school boards to use "alternative" financing and project delivery methods — subject to BPW regulation — and contemplates that those methods of building schools might not involve the normal competitive bidding process. ED § 4-126.

Under its statutory authority, and on the recommendation of the IAC, the BPW has adopted regulations that permit local systems to draw upon intergovernmental cooperative purchasing agreements for various needs. The key regulation authorizes the use of intergovernmental cooperative purchasing not only to buy goods and commodities but also to purchase "requirements" under an intergovernmental purchasing agreement of another governmental entity. COMAR 23.03.03.12A. Under the regulation, a local school system may use such an intergovernmental purchasing agreement if it is not attempting to avoid competition and if it perceives benefits, in terms of cost, efficiency, or governmental cooperation, from that use. COMAR 23.03.03.12B. The regulation identifies two common types of intergovernmental purchasing arrangements — pooling and piggybacking. COMAR 23.03.03.12C.

Whether roofing repair services could ever be characterized as a "good" or "commodity," they were certainly among the "requirements" of the Board of Education to maintain adequate school facilities. The AEPA contract utilized by the Board of Education appears to be a form of pooling. In electing to use such a contract, the Board of Education perceived benefits in terms of cost and other factors.29

One might read the BPW regulations narrowly to allow participation in intergovernmental cooperative purchasing organizations only for the purchase of goods and commodities. In that view, the regulations were simply meant to incorporate ED § 5-112(a)(3) — it would not be the first time that a regulation simply reiterated a statute. But it seems unlikely that the BPW's three regulations authorizing the use of cooperatives were meant to pertain to the purchase of pencils and textbooks — items not within the purview of the BPW or IAC. Moreover, the BPW placed these regulations all in a chapter of regulations devoted to public school construction that it entitled "Construction Procurement Methods."

In approving and funding the various roofing services contracts submitted by the Board of Education, the BPW agreed that they were within the purview of its regulations.30 Thus, when it utilized cooperative purchasing contracts for roof repair, the Board of Education was not engaged in its own frolic and detour. The contracts were entered into and funded with the express approval of the two agencies that the General Assembly has directed to oversee local school construction. Indeed, in discussing the type of intergovernmental cooperative purchasing arrangements permitted under the BPW regulations, an IAC report alluded to the roofing construction contracts of the Board of Education to illustrate the benefits of a purchasing cooperative. Interagency Committee On School Construction, Alternative Approaches to the Construction of Public School Facilities: Annual Report on the Status of Alternative Procurement, Project Delivery, and Financing for Maryland Public School Construction 15 (2007).31

In sum, ED § 5-112 embodies a longstanding requirement that local school systems generally use competitive bidding for procurement. But that prescription cannot be viewed in isolation from the history of the State's growing involvement in local school construction, the significant authority delegated to the BPW and IAC to oversee school construction, and the several authorizations for local school systems to use alternative methods of financing, procurement, and project delivery (of which the exception in ED § 5-112(a)(3) is just one example). The pertinent regulations, as applied by the BPW and IAC, allow for greater use of intergovernmental purchasing cooperatives for construction services.

Conclusion

We hold that ED § 5-112 does not bar the Board of Education from procuring its needs for roofing repair services through an intergovernmental purchasing cooperative when it acts pursuant to the authority of a BPW regulation that had been adopted in accordance with a legislative delegation of authority to the BPW. Whether it is wise to use a purchasing consortium for roof repair services is not for us to assess; we only determine whether that decision was within the authority granted to the Board of Education by the BPW under its statutory delegation — a delegation that the Legislature may retract or modify. If those decisions are imprudent, it is the General Assembly that holds the ultimate trump card.
