The central issue in this case is whether a county’s constructive approval of a water and sewer service proposal submitted by a non-profit corporation under former S.C.Code Ann. § 33-35-90 grants the non-profit corporation exclusive service rights such that the county may not give franchise rights to competing providers within the same service areas designated in the proposal. Williamsburg Rural Water and Sewer Company, Inc. (Williamsburg Water) commenced this action against Williamsburg County, Williamsburg County Water and Sewer Authority, and the Town of Kingstree (collectively, the County)1 seeking: (1) a determination that Williamsburg Water possessed an exclusive right to provide water and sewer service within designated unincorporated areas in Williamsburg County, (2) damages in tort based on the County’s interference with that right, and (3) injunctive relief. The circuit court granted summary judgment to the County, finding that Williamsburg Water did not possess an exclusive *255service right and that Williamsburg Water’s cause of action in tort was barred by the South Carolina Tort Claims Act and the statute of limitations. Williamsburg Water appeals. We affirm.
FACTSIPROCEDURAL HISTORY
The relevant facts of this case are largely undisputed and are gathered from a timeline of events to which the parties stipulated. On January 16, 1995, W.N. Kellahan, an organizer of Williamsburg Water, sent a letter to Elwood Gerald, the County’s director of rural and community development, notifying the County of Williamsburg Water’s intention to provide service to certain unincorporated areas of Williamsburg County pursuant to S.C.Code Ann. § 33-35-90 (1990).2 Section 33-35-90 sets forth the statutory mechanism for a non-profit corporation to provide water and sewer services within the geographical areas designated in its articles of incorporation, provided the corporation notifies the county of the nature of the services to be provided and receives the county’s consent.
In March and again in April of 1995, Kellahan appeared before the Williamsburg County Council on behalf of Williams-burg Water to reiterate Williamsburg Water’s intent to provide services to the designated areas. Kellahan sent a copy of Williamsburg Water’s master plan to the council and to Gerald. In May of 1995, Williamsburg Water filed its articles of incorporation with the Secretary of State. Shortly thereafter, Williamsburg Water began applying for loans and federal grants to fund its operation.
During this same time period, the county council began considering enacting an ordinance that would allow the County to expand its own water and sewer services into the same unincorporated areas that Williamsburg Water intended to service. The proposed ordinance allowed the County to grant franchises to organizations that submitted applications to the County seeking permission to provide service within these same areas.
*256The first of three public readings of the proposed franchise ordinance was held on March 6, 1995. On August 7 of that year, the ordinance was adopted. In May of 1998, the County applied for federal funding to construct its water system. On November 3, 1998, the County solicited bids for water and sewer services to the Industrial Park area, which is located within the service area designated in Williamsburg Water’s 'proposal. The County awarded the bid to Tom Brigman Contractor’s, Inc., of Newberry, on November 9,1998.
In response, Williamsburg Water commenced this action against the County on December 4, 1998, claiming that Williamsburg Water possessed an exclusive right to provide services to the unincorporated areas specified in its proposal, including the area where the Industrial Park was located. In essence, Williamsburg Water claimed that its proposal was approved by the County by virtue of the County’s failure to notify Williamsburg Water to the contrary in accordance with section 33-35-90. Williamsburg Water further claimed the County intentionally interfered with and/or threatened to interfere with Williamsburg Water’s ability to obtain federal funding and to provide service within the designated areas. The complaint alleged that as a result of the County’s grossly negligent actions, Williamsburg Water suffered injury and damages. Finally, Williamsburg Water sought a declaration that it was exempt from the County’s franchise ordinance and that it possessed an exclusive right to service the unincorporated areas designated in its proposal.
Williamsburg Water and the County filed cross motions for summary judgment. The circuit court granted summary judgment to the County on Williamsburg Water’s first cause of action, ruling that Williamsburg Water had the right, but not the exclusive right, to provide water and sewer service to the designated areas. The circuit court also granted summary judgment to the County on Williamsburg Water’s action in tort, finding the County was immune from liability under the South Carolina Tort Claims Act and that the statute of limitations had run. However, the circuit court found there was a genuine issue of material fact as to whether Williams-burg Water was exempt from the County’s franchise ordinance. This appeal follows.
*257 STANDARD OF REVIEW
“When reviewing the grant of summary judgment, the appellate court applies the same standard applied by the trial court pursuant to Rule 56(c), SCRCP.” Fleming v. Rose, 350 S.C. 488, 493, 567 S.E.2d 857, 860 (2002). Summary judgment is appropriate when “the pleadings, depositions, answers to inteirogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law.” Rule 56(c), SCRCP. Once the party moving for summary judgment meets the initial burden of showing an absence of evidentiary support for the opponent’s case, the non-moving party must come forward with specific facts showing there is a genuine issue for trial. Id.; SSI Med. Servs., Inc. v. Cox, 301 S.C. 493, 497, 392 S.E.2d 789, 792 (1990). “In determining whether any triable issue of fact exists, the evidence and all inferences which can be reasonably drawn therefrom must be viewed in the light most favorable to the nonmoving party.” Worsley Cos. v. Town of Mount Pleasant, 339 S.C. 51, 55, 528 S.E.2d 657, 659 (2000).
LAW/ANALYSIS
I. Exclusive Service Rights
The circuit court found that the notices contained in Williamsburg Water’s proposal dated January 16, 1995, were both proper and adequate to comply with section 33-35-90. Moreover, the circuit comb held Williamsburg Water possessed the right, but not the exclusive right, to provide service within the disputed area. The County did not appeal either of these findings; therefore, it is the law of this case that Williamsburg Water possesses a right to provide water and sewer services in Williamsburg County. See Bakala v. Bakala, 352 S.C. 612, 576 S.E.2d 156 (2003); Charleston Lumber Co. v. Miller Housing Corp., 338 S.C. 171, 525 S.E.2d 869 (2000) (stating an unappealed ruling is the law of the case). The question before this court is whether that right is an exclusive service right, such that the County is prohibited from awarding franchises within the areas identified in Williamsburg Water’s proposal.
*258The circuit court’s order does not indicate the basis for its finding that Williamsburg Water possesses a right to provide service in the county. We presume the circuit court found this right to be the product of the County’s failure to comply with the mandatory notice provisions of section 33-35-90, for there is no other explanation in the order for the creation of this right. It is the law of this case that Williamsburg Water possesses a right of some degree; thus, determining the source of that right is not necessary to its existence. However, we believe it is necessary for a complete understanding of the controversy in this case to briefly set forth our view regarding the County’s failure to comply with section 33-35-90, which must be the foundation for the circuit court’s ruling.
Section 33-35-90 (1990) stated in relevant part:
[P]rior to providing any of the services authorized in this section, nonprofit corporations or groups intending to organize such corporations shall first notify the governing body, of the county or municipality in which the services are to be provided, of their intentions and the nature of such services. The governing body shall, from the date of such notification, have a period of ninety days in which to approve the request to provide such services or inform the persons requesting permission to provide such services that the governing body intends to provide for such matters as a public function of government. Any such notification of intent by the governing body shall include a detailed description of the area to be served, the services to be provided and the time schedule under which such services will be available from the county or municipality.
(Emphasis added).
“The cardinal rule of statutory construction is to ascertain and effectuate the legislative intent whenever possible.” Strother v. Lexington County Recreation Comm’n, 332 S.C. 54, 62, 504 S.E.2d 117, 121 (1998). “Unless there is something in a statute requiring a different interpretation, the words used in the statute must be given their ordinary meaning.” Mullinax v. J.M. Brown Amusement Co., 326 S.C. 453, 458, 485 S.E.2d 103, 106 (Ct.App.1997). “The language must also be read in a sense which harmonizes with its subject matter and accords with its general purpose.” Hitachi Data Sys. *259Corp. v. Leatherman, 309 S.C. 174, 178, 420 S.E.2d 843, 846 (1992). “Statutes, as a whole, must receive practical, reasonable, and fair interpretation, consonant with the purpose, design, and policy of lawmakers.” TNS Mills, Inc. v. South Carolina Dep’t of Revenue, 331 S.C. 611, 624, 503 S.E.2d 471, 478 (1998).
Section 33-35-90 unambiguously required the County to respond to Williamsburg Water’s proposal within ninety days of its receipt. The statute further required the County to inform Williamsburg Water of its intention to provide such services and to give a detailed description of any area it wished to serve, as well as a time schedule for the availability of such services. Although the first reading of the proposed ordinance occurred within ninety days of Williamsburg Water’s application, there is no evidence the reading of the ordinance notified Williamsburg Water that the County had rejected its proposal or that it described with detail the area it wished to service, the nature of services to be provided, and the time schedule for the availability of such services. Section 33-35-90 mandates that “any” such notification by the County “shall” include such information. It is irrelevant that representatives of Williamsburg Water attended the reading of the proposed ordinance because the reading did not satisfy the requirements of the statute. The County, therefore, failed to comply with section 33-35-90.
Unlike current section 33-36-270,3 the former statute does not specifically state that a governing body’s failure to respond to a non-profit corporation’s proposal serves as an acceptance of the corporation’s proposal. However, we believe the use of affirmative language stating that the County “shall ... have a period of ninety days” in which to respond imposes an obligation upon the County to take action in accordance with the statute. See Horry County v. City of Myrtle Beach, 288 S.C. 412, 419, 343 S.E.2d 36, 39 (Ct.App.1986) (stating the words “shall” and “must” are generally regarded as making a provision mandatory). Considering its overall purpose and the mandatory terms chosen by the legislature, we believe the *260only logical construction of section 33-35-90 is that the County’s failure to respond -within the ninety-day time limit constitutes approval of Williamsburg Water’s proposal.4
We turn now to address the extent of the service rights acquired by Williamsburg Water as a result of the County’s implicit approval of the proposal. Williamsburg Water argues its right to provide water and sewer services is exclusive; therefore, the County was prohibited from awarding franchises within the proposed service area. The County disagrees, contending that Section 15 of Article VIII of the South Carolina Constitution safeguards the County’s right to choose whomever it desires to provide such services to its citizens.
Section 15 of Article VIII states in pertinent part:
[N]or shall any law be passed by the General Assembly granting the right to construct and operate in a public street or on public property a street or other railway, or to erect waterworks for public use, or to lay water or sewer mains for any purpose, or to use the streets for any facility other than telephone, telegraph, gas, and electric, ivithout first obtaining the consent of the governing body of the county ....
(Emphasis added).
Section 15 of Article VIII of the South Carolina Constitution prohibits the legislature from passing a law which grants the right to lay water or sewer mains without first obtaining a county’s consent. See City of Aiken v. Aiken Elec. Co-op., Inc., 305 S.C. 466, 468, 409 S.E.2d 403, 404 (1991). However, section 15 conveys only a veto power; it is not a franchising mechanism. See City of Abbeville v. Aiken Elec. Co-op., Inc., 287 S.C. 361, 368, 338 S.E.2d 831, 835 (1985) (“The consent provision of § 15 is not an affirmative grant of franchise power, but is a restriction on legislative authority.”) (Emphasis in original). Therefore, prior to receiving the County’s consent, Williamsburg Water was prohibited from entering into any area of the county because Section 15 of Article VIII acted as a shield barring any such intrusion without the County’s approval. In this case, the County’s *261constructive consent simply removed this constitutional shield; it did not, however, convert a previously non-existent right into a right that is exclusive against all others, including the County. Nothing in section 33-35-90 or case law of this state suggests such an extensive interpretation.
The cases in South Carolina that have addressed conflicts between rural service providers and governmental bodies give little guidance under the facts of this case. Both parties directed this court’s attention to the line of cases involving annexation, including City of Aiken and City of Abbeville, as well as City of Rock Hill v. Pub. Serv. Comm’n of S.C., 308 S.C. 175, 417 S.E.2d 562 (1992), South Carolina Electric & Gas Co. v. Berkeley Elec. Co-op., Inc., 306 S.C. 228, 411 S.E.2d 218 (1991), Berkeley Elec. Co-op., Inc. v. S.C. Pub. Serv. Comm’n, 304 S.C. 15, 402 S.E.2d 674 (1991), and Blue Ridge Elec. Co-op., Inc. v. City of Seneca, 297 S.C. 283, 376 S.E.2d 514 (1989).
In this line of cases, the common facts involved a municipality’s annexation of land which was within an area that the Public Service Commission had assigned to a rural service provider. An irreconcilable conflict developed between the alleged right of the rural service provider to expand its services within its assigned area and the municipality’s right to determine who would provide services within the newly incorporated area. Cf., City of Rock Hill, 308 S.C. at 178, 417 S.E.2d at 564. If the rural service provider possessed an exclusive right to service the area, the municipality could not offer the services. However, the municipality could prevent the rural service provider from using the municipality’s streets to extend its services by refusing to give consent as provided for in Section 15 of Article VIII. The result of this situation would be that the citizens within the disputed area would effectively be denied service because the rights possessed by each would prevent the other from servicing the area. Cf. id.; Blue Ridge, 297 S.C. at 289, 376 S.E.2d at 517-18. The supreme court refused to compel the municipalities to give their consent to the assigned provider because limiting a municipality’s right to choose fatally undermines the concept of consent. Cf., City of Rock Hill, 308 S.C. at 178, 417 S.E.2d at 564; Blue Ridge, 297 S.C. at 289, 376 S.E.2d at 517-18. Instead, the supreme court found the service rights possessed *262by the provider were not exclusive and that the right of consent embodied the right of the municipality to designate a supplier of the municipality’s choosing. Cf., Berkeley Elec. Coop., 304 S.C. at 19-20, 402 S.E.2d at 677.
We find the annexation cases inapposite because in those cases, the source of the provider’s service rights was an assignment by the Public Service Commission whereas Williamsburg Water acquired its service right as a result of the County’s consent, which resulted from the County’s failure to comply with section 33-35-90. Thus, unlike the annexation cases, the governmental body invading Williamsburg Water’s proposed service area is the same body from which consent was obtained for that service. Moreover, in the annexation cases, the service providers were allowed to continue servicing areas where they maintained existing service. In this case, Williamsburg Water has no existing service facilities anywhere within the disputed region. There are two fundamental elements underlying the annexation cases which distinguish them from this case: (1) the governing body never consented to the provider, and (2) the provider had existing service in some portion of the disputed area. Because neither of these elements is present here, the annexation cases offer little guidance in resolving a dispute of this posture.
By failing to comply with section 33-35-90, the County consented to Williamsburg Water’s service proposal. Therefore, unlike in the annexation cases, this factor is decided in favor of Williamsburg Water. However, nothing in section 33-35-90 suggests that the receipt of constructive consent is tantamount to obtaining a right so exclusive as to operate against the very entity from which the consent was initially required. Williamsburg Water’s service rights are not superi- or to the County’s own right to decide who will provide water and sewer services to its citizens, especially considering that Williamsburg Water has no existing service facilities in place as seen in the annexation cases.5
*263The difficulty of this case lies in giving effect to the rights acquired by Williamsburg Water as a result of the County’s failure to comply with section 33-35-90. If this statute is to have any meaning, there must be some enforceable quality belonging to those rights; otherwise, a party obtaining approval under this statute receives, in effect, nothing at all. Complicating the matter is the fact that during the pendency of this appeal, the County awarded numerous franchises affecting the disputed area, and those facilities are presently under development for the benefit of the people of Williams-burg County. Thus, in this case, valid but competing interests are diametrically opposed. An unfortunate result of our ruling today is that Williamsburg Water likely possesses a right which has little commercial value in light of the County’s intrusion into the designated service area. Nevertheless, in the absence of case law on point, and without specific language in section 33-35-90 compelling the grant of exclusive rights, we hold that Williamsburg Water does not possess an exclusive service right within the described service area; rather, as the circuit court found, it possesses a non-exclusive service right.
II. Applicability of the Franchise Ordinance to Williamsburg Water
Williamsburg Water argues the trial court erred in failing to find as a matter of law that it was exempt from the County’s franchise ordinance because it was a bona fide water/sewer system as defined by the ordinance. This issue is not directly appealable.
The supreme court’s recent decision in Olson v. Faculty House of Carolina, Inc., 354 S.C. 161, 580 S.E.2d 440 (2003), resolves the issue of the appealability of the denial of a motion for summary judgment. While in the past this court has, in its discretion, heard an appeal from the denial of summary judgment where there was another appealable issue before the court, that is no longer the rule in South Carolina. Olson expressly holds “the denial of a motion for summary judgment is not appealable, even after final judgment.” In so holding, the supreme court expressly overruled cases that are inconsistent with this rule. Id.
*264In this case, the trial court found there was a genuine issue of material fact as to whether Williamsburg Water was a bona fide water/sewer system thereby exempting it from the County’s franchise ordinance. On remand, the trial court must first decide whether the ordinance is capable of being applied to Williamsburg Water in consideration of the timing and manner of its enactment.6 Should the trial court determine the ordinance is capable of being applied to Williamsburg Water, it must then determine whether Williamsburg Water is exempt from the ordinance under either of the prescribed circumstances stated in the ordinance. See Section II, Williams-burg County Ordinance No.1995-3 (“All areas of the county not now served by an existing bona fide water/sewer system or located within a County Council approved water/sewer service area are hereby designated as within the County water/sewer system service area.”). Pursuant to the express terms of the ordinance, all areas that qualify under either of the exemptions stated above are not within the County’s water/sewer system service area.
The fact that this issue is not directly appealable does not preclude the parties from again moving for summary judgment on this issue on the same or other grounds not previously considered by the trial court. The denial of summary judgment does not finally determine the merits of the case, and issues raised in a motion may be raised again in a motion to reconsider summary judgment or in a motion for directed verdict. Brown v. Pearson, 326 S.C. 409, 416-17, 483 5.E.2d 477, 481 (Ct.App.1997). The parties may make a later motion for summary judgment based on matters not involved in the decision on the first motion. Croswell Enters., Inc. v. Arnold, 309 S.C. 276, 279, 422 S.E.2d 157, 159 (Ct.App.1992).
III. The South Carolina Tort Claims Act
A. The County’s immunity from liability
Williamsburg Water maintains the circuit court erred in granting summary judgment to the County on Williamsburg Water’s tort cause of action because there was a genuine issue *265of material fact as to whether the County acted in a grossly negligent manner. We disagree.
Williamsburg Water alleged that the County’s gross negligence in undertaking to provide water and sewer service to areas designated in Williamsburg Water’s approved proposal caused Williamsburg Water damages as a result of its inability to obtain federal funding and, likewise, to provide service within the exclusive service area. The circuit court found the County was immune from liability under the South Carolina Tort Claims Act.
The South Carolina Tort Claims Act declares that the State, its agencies, political subdivisions, and other governmental entities are “liable for their torts in the same manner and to the same extent as a private individual under like circumstances,” subject to certain limitations and exemptions within the Act. S.C.Code Ann. § 15-78-40 (Supp.2002). Section 15-78-60 sets forth exceptions to this waiver of sovereign immunity, and the exceptions restore certain limitations on the liability of a governmental entity. S.C.Code Ann. § 15-78-60 (Supp.2002). Section 15-78-60(12) provides that a government entity is not liable for loss resulting from:
licensing powers or functions including, but not limited to, the issuance, denial, suspension, renewal, or revocation of or failure or refusal to issue, deny, suspend, renew, or revoke any permit, license, certificate, approval, registration, order, or similar authority except when the power or function is exercised in a grossly negligent manner [.]
(Emphasis added).
“Gross negligence is the intentional, conscious failure to do something which it is incumbent upon one to do or the doing of a thing intentionally that one ought not to do.” Clyburn v. Sumter County Sch. Dist. No. 17, 317 S.C. 50, 53, 451 S.E.2d 885, 887 (1994). “It is the failure to exercise even the slightest care.” Faile v. South Carolina Dep’t. of Juvenile Justice, 350 S.C. 315, 331-32, 566 S.E.2d 536, 544 (2002). “Gross negligence ... means the absence of care that is necessary under the circumstances.” Etheredge v. Richland Sch. Dist. One, 341 S.C. 307, 310, 534 S.E.2d 275, 277 (2000). “Additionally, while gross negligence ordinarily is a mixed question of law and fact, when the evidence supports but one *266reasonable inference, the question becomes a matter of law for the court.” Id.
Although the County failed to comply with section 33-35-90 regarding notice to Williamsburg Water, there is no evidence to support Williamsburg Water’s allegation that the County’s conduct rose to the level of gross negligence. The record contains no indication that the County intentionally sought to interfere with Williamsburg Water’s ability to service the area. Rather, the evidence suggests the County proceeded under the mistaken impression that it satisfied the notice provisions of section 33-35-90 when it gave public readings of the proposed ordinance. Accordingly, contrary to Williamsburg Water’s contention, the evidence indicates the County was unaware that Williamsburg Water had acquired any service rights within the disputed area. Therefore, we believe the only reasonable inference from the evidence is that any intrusion by the County upon Williamsburg Water’s service rights was unintentional and not the product of gross negligence. The Tort Claims Act bars recovery from government entitiés under such circumstances.
B. The statute of limitations
Williamsburg Water argues the trial court erred in determining its tort claims against the County were barred by the statute of limitations. We need not decide this issue in light of our holding that the County was entitled to summary judgment based on the lack of evidence supporting Williams-burg Water’s claim of gross negligence.
CONCLUSION
We hold today that section 33-35-90 does not convey exclusive service rights to Williamsburg Water on the facts of this case. Nothing in the statutory language suggests such an extensive interpretation, and a contrary finding would be inconsistent with our view of the veto power granted to counties and municipalities by virtue of Section 15 of Article VIII of the South Carolina Constitution. By failing to act, the County consented to Williamsburg Water’s proposal, but that consent does not transform a non-existent service right into an exclusive service right.
*267We also affirm the circuit court’s grant of summary judgment in favor of the County with respect to Williamsburg Water’s causes of action in tort, holding that the County is immune from liability under the South Carolina Tort Claims Act. The denial of summary judgment as to whether the franchise ordinance applies to Williamsburg Water is not appealable, and that issue is remanded to the circuit court for further proceedings consistent with this opinion.
AFFIRMED.
CURETON, HUFF, HOWARD, BEATTY, JJ., and JEFFERSON, A.J., concur.. Williamsburg Water named the Town of Hemingway and Barrineau Water Company, Inc., as defendants in the case, but these defendants were later dismissed as parties.
. In October of 2000, section 33-35-90 was repealed and replaced with section 33-36-270.
. S.C.Code Ann. § 33-36-270 (2000) includes the following language: "Failure to notify the corporation within ninety days of the governing body’s approval or intent to serve is considered approval."
. Because only the extent of the service right is in issue, and not the existence thereof, we need not address Williamsburg Water'q argument that section 33-36-270 applies retroactively to these facts.
. We recognize that the lack of existing facilities is likely the result of Williamsburg Water's inability to obtain funding due to the circumstances surrounding the County's award of franchises for the same areas which Williamsburg Water desired to service. However, we cannot ignore the absence of facilities in light of its significance in the annexation cases.
. During oral argument, counsel for Williamsburg Water conceded that it is subject to certain aspects of the ordinance.
