Janet Miller, petitioner, seeks review of a decision rendered by the Court of Special Appeals, Comptroller of Maryland v. Miller, 169 Md.App. 321, 901 A.2d 229 (2006), in favor of the Comptroller of Maryland, respondent. In simple terms, this case involves whether an employee of the State is entitled to be paid as “work time” for the entire time spent driving from home directly to an out-of-regular workplace site, or whether the employee’s normal commute time to the regular workplace is to be deducted from the time spent driving to the out-of-workplace site. To resolve this issue, we must examine the relationship between two regulatory schemes pertaining to State employees.1
*275The problem in this case arises because the provision of the Code of Maryland Regulations (COMAR) that regulates the entitlement of “time” compensation requires that such compensation be awarded “in accordance” with the provisions of another regulatory scheme that regulates the entitlement to mileage compensation. Petitioner asserts that the time compensation statute should not be deemed to be qualified by the limitation language of the mileage compensation. Respondent argues otherwise, in the process pointing out certain absurd results that might occur if the Court were to adopt petitioner’s position.2
In separate proceedings before an Administrative Law Judge (ALJ) and the Circuit Court for Baltimore City, petitioner’s position prevailed. The Court of Special Appeals *276reversed. We granted certiorari. Miller v. Comptroller, 395 Md. 56, 909 A.2d 259 (2006). Before this Court, petitioner presents two questions:
“I. Does COMAR 17.04.11.02B(l)(j) entitle employees to compensation for all time spen[t] traveling between home and a work site other than the assigned office?
“II. Does the law require that Petitioner's] remedy be limited to compensation for 20 days prior to the filing of her grievance?”
We answer no to the first question, yes to the second and, in so doing, affirm the judgment of the Court of Special Appeals.
I. Procedural History
Petitioner’s job in the Comptroller’s office, Financial Compliance Officer, required her to conduct audits at field locations going directly to remote locations from her home. At the time petitioner began working in that office, the Comptroller’s policy was that an employee who was required to drive directly to a remote work site from her home was entitled to time compensation3 for only that period of time that exceeded her normal commute time by thirty minutes.
Approximately two years after she began her employment, she met with a representative of the Maryland Classified Employees Association who informed her that the Comptroller was required to pay her for the time from when she left her home, until she arrived at a remote audit location. Petitioner then filed a grievance with the Comptroller in which she sought payment for her time from home to the remote audit location. A decision was issued in the first step of the grievance process which authorized compensation for all travel time in excess of petitioner’s normal commute time, but the period of such compensation was limited to commutes taking place within a 30 day period prior to the filing of the griev*277anee.4 Petitioner appealed that first-step decision, contending that she should be entitled to compensation for the entire period of her travel to a remote site and not just the period of time in excess of her normal commute. She also challenged the 30 day limitation.
The decision in the second-step appeal was rendered by a Deputy Comptroller who affirmed the first-step decision except that he reduced the 30 day period to 20 days in order to comply with Maryland Code (1993, 2004 RepLVol.), § 12-203(b) of the State Personnel and Pensions Article.5 In affirming the commute-time issue, the Deputy Comptroller recognized the interrelationship between the two regulations at issue here and quoted with approval the finding of the Director of the Compliance Division:
“ T believe that COMAR 17.04.11.02B(l)(j), incorporating the Standard Travel Regulations, is intending to apply the quoted mileage reimbursement concept in determining whether an employee is on work time or commute time. Applying that concept to this situation, for those days when Ms. Miller does not travel to her assigned office, she would properly be viewed as being on work time for all time directly connected with the business trip, in excess of her normal commute time.’ ”
Petitioner then filed a third-step appeal to the Secretary of Budget and Management, who delegated the case to the Office of Administrative Hearings. Petitioner’s position appeared to *278be that she was entitled to financial time compensation for every minute of time she was driving directly from her home to a remote work site, even if the commute time to the remote site was less than her normal commute time.6 The Comptroller argued that adopting petitioner’s position on this point could lead to absurd results. Petitioner also asserted that she was entitled to back compensatory pay despite the limitation of the 20 day period that had been one aspect of the Deputy Comptroller’s decision. Both sides, with an important exception, then proffered testimony with respect to their positions to the Administrative Law Judge (ALJ). The exception was that petitioner chose not to put on evidence of the actual hours for which she contended she was entitled to compensation.7
On the primary issue, the ALJ decided on behalf of petitioner and against the Comptroller. In pertinent part, the ALJ opined:
“The Board of Public Work’s Standard Travel Regulations apply to all executive branch State employees. CO-MAR 23.02.01.02B(14) provides as follows:
‘(14) “Travel status” means the condition of a State employee while traveling on State business. An employee is not in travel status while commuting from home to the employee’s assigned office, regardless of the length of time of that commute.’
Thus, by promulgated regulation, it is the policy of all executive agencies in the State (unless otherwise exempted) that an employee traveling from home to a field site, and *279not to the employee’s assigned office, is on “work time’ and in ‘travel status.’ An employee is to be paid or compensated for ‘work time.’ When traveling to a field site, an employee is working for the State, ‘on the clock’ so to speak, from the time the employee leaves the residence or the place from which the normal commute to the assigned office would begin.
“With regard to reimbursing travel time, the Agency currently subtracts out the estimated, round trip travel time to the assigned office on those days when an employee does not commute to the employee’s assigned office.
“There is no direct legal authority to allow the agency to deduct from an employee compensation for the work time while on travel status.... I am not persuaded by the agency’s argument on that point. I conclude that [petitioner] has met her burdens to show that the Agency misapplied the statewide policy in formulating its own travel time policy.
“[Petitioner] offered no credible evidence regarding the calculation of uncompensated work hours.... ” (Citations omitted.)
Ultimately, however, the ALJ dismissed the grievance, finding:
“I conclude, as a matter of law, that [petitioner] demonstrated that the Agency’s revised travel time policy did not conform to law and regulation. I further conclude, however, that [petitioner] did not meet her burdens with regard to demonstrating that she is entitled to compensation for certain, uncompensated work time.” (Citations omitted.)
Both parties sought judicial review. The Circuit Court agreed with the ALJ that the Comptrollers revised travel policy was not supported by law. That court, however, remanded the case back to the Office of Administrative Hearings for a further hearing, presumably in order for petitioner to present evidence before an ALJ to establish what compen*280sation she was due. The Comptroller appealed to the Court of Special Appeals and that court reversed the decision of the Circuit Court and the decision of the AL J.8
II. Standard of Review
In Kane v. Board of Appeals of Prince George’s County, we recently noted that:
“' “We review an administrative agency’s decision under the same statutory standards as the Circuit Court.” ’ Annapolis Market Place, L.L.C. v. Parker, 369 Md. 689, 703, 802 A.2d 1029, 1037 (2002) (quoting Jordan Towing, Inc. v. Hebbville Auto Repair, Inc., 369 Md. 439, 449-52, 800 A.2d 768 (2002)). In Board of Physician Quality Assurance v. Banks, 354 Md. 59, 67-69, 729 A.2d 376, 380-81 (1999), Judge Eldridge, writing for the Court, explained the standard of review for administrative agency decisions:
‘ “A court’s role in reviewing an administrative agency adjudicatory decision is narrow, United Parcel v. People’s Counsel, 336 Md. 569, 576, 650 A.2d 226, 230 (1994)”; it “is limited to determining if there is substantial evidence in the record as a whole to support the agency’s findings and conclusions, and to determine if the administrative decision is premised upon an erroneous conclusion of law. United Parcel, 336 Md. at 577, 650 A.2d at 230.’””
Kane, 390 Md. 145, 159, 887 A.2d 1060, 1068 (2005). When reviewing agency decisions of law, such as the meaning of “full back pay” in § 11—110(d)(l)(iii) of the State Personnel and Pensions Article, we:
“[C]onduct[ed] a de novo review of the ALJ’s legal conclusion that benefits are not included in ‘full back pay' as the question is one of statutory interpretation and, therefore, a purely legal inquiry. Schwartz v. Dep’t of Natural Res., 385 Md. 534, 554, 870 A.2d 168, 180 (2005); Charles County Dep’t of Soc. Servs, v. Vann, 382 Md. 286, 295, 855 A.2d 313, *281319 (2004); Spencer v. Bd. of Pharmacy, 380 Md. 515, 528-29, 846 A.2d 341, 348-49 (2004); Coleman v. Anne Arundel County Police Dep’t, 369 Md. 108, 121, 797 A.2d 770, 778 (2002).”
Reier v. State Dept. of Assessments and Taxation, 397 Md. 2, 915 A.2d 970 (2007) (No. 29, September Term, 2006).
With respect to the distinction between the standard of review used for agency findings of fact, which we are not asked to review herein,9 and agency conclusions of law, which we are asked to review, we have said:
“ ‘Even with regard to some legal issues, a degree of deference should often be accorded the position of the administrative agency. Thus, an administrative agency’s interpretation and application of the statute which the agency administers should ordinarily be given considerable weight by reviewing courts. Lussier v. Md. Racing Commission, 343 Md. 681, 696-697, 684 A.2d 804, 811-12 (1996), and cases there cited; McCullough v. Wittner, 314 Md. 602, 612, 552 A.2d 881, 886 (1989) (‘The interpretation of a statute by those officials charged with administering the statute is ... entitled to weight’). Furthermore, the expertise of the agency in its own field should be respected.’ ”
Maryland Aviation Admin. v. Noland, 386 Md. 556, 572, 873 A.2d 1145, 1154-55 (2005) (footnote omitted). In Schwartz v. Maryland Depar’t of Natural Resources, 385 Md. 534, 870 *282A.2d 168 (2005), we more specifically addressed the deference due administrative decisions, depending on whether the issue was factual or legal and we described the lesser degree of deference due by courts of legal decisions of administrative entities:
“With respect to an agency’s conclusions of law, we have often stated that a court reviews de novo for correctness. We frequently give weight to an agency’s experience in interpretation of a statute that it administers, but it is always within our prerogative to determine whether an agency’s conclusions of law are correct, and to remedy them if wrong.”
Schwartz, 385 Md. at 554, 870 A.2d at 180 (citations omitted). See also Christopher v. Montgomery County Department of Health and Human Services, 381 Md. 188, 198, 849 A.2d 46, 52 (2004) (“Determining whether an agency’s ‘conclusions of law' are correct is always, on judicial review, the court’s prerogative, although we ordinarily respect the agency’s expertise and give weight to its interpretation of a statute that it administers. Of course, even though an agency’s interpretation of a statute is often persuasive, ‘the reviewing court must apply the law as it understands it to be.’ ” (citations omitted)).
III. Discussion
A Compensation for Commuting to a Non-Regular Work Site.
This case requires us to interpret the rules of an agency of this State. We stated in Maryland Com’n on Human Relations v. Bethlehem Steel Corp., 295 Md. 586, 592-93, 457 A.2d 1146, 1149 (1983), that “the interpretation of an agency rule is governed by the same principles that govern the interpretation of a Statute.” We have often stated the rules of statutory construction:
“ ‘The cardinal rule of statutory interpretation is to ascertain and effectuate the intention of the legislature. Fish Market v. G.A.A., 337 Md. 1, 8, 650 A.2d 705 (1994). See also Jones v. State, 336 Md. 255, 260, 647 A.2d 1204 *283(1994); Parrison v. State, 335 Md. 554, 559, 644 A.2d 537 (1994); Rose v. Fox Pool, 335 Md. 351, 358, 643 A.2d 906 (1994). The first step in determining legislative intent is to look at the statutory language and ‘[i]f the words of the statute, construed according to their common and everyday meaning, are clear and unambiguous and express a plain meaning, we will give effect to the statute as it is written.’ Jones, supra, 336 Md. at 261, 647 A.2d [ ] [at 1206]. See also Parrison, supra, 335 Md. at 559, 644 A.2d [ ] [at 539]; Rose, supra, 335 Md. at 359, 643 A.2d [ ] [at 909]; Outmezguine v. State, 335 Md. 20, 41, 641 A.2d 870[, 880] (1994).’
See also Greco v. State, 347 Md. 423, 429, 701 A.2d 419, 422 (1997) (noting that our goal is to give statutes their ‘most reasonable interpretation, in accord with logic and common sense, and to avoid a construction not otherwise evident by the words actually used’); Frost v. State, 336 Md. 125, 137, 647 A.2d 106, 112, (1994) (stating that we will seek to avoid statutory constructions that are ‘illogical, unreasonable, or inconsistent with common sense’).”
Rockwood Casualty Ins. Co. v. Uninsured Employers’ Fund, 385 Md. 99, 108-09, 867 A.2d 1026, 1031 (2005) (quoting Oaks v. Connors, 339 Md. 24, 35, 660 A.2d 423, 429 (1995)).
With these principles of construction guiding us, we turn to Judge Hollander’s well-reasoned opinion where she explained the Court of Specials Appeals’ position on the commute-time issue we address today:
“We agree with appellant [the Comptroller of Maryland] that the ALJ’s conclusion is inconsistent with the plain meaning of the regulations. Therefore, the ALJ’s decision is ‘premised on an erroneous conclusion of law.’ ...
“COMAR 17.04.11.02B([l])(j) plainly defines ‘work time’ as the time during which an employee ‘[t]ravels between home and a work site other than the assigned office, in accordance with the Standard Travel Regulations under COMAR 23.02.01.’ ... However, the Standard Travel Regulations under COMAR 23.02.01.01(c)(2) provide: ‘Reim*284bursement to employees ... who use State-owned, State-leased or privately owned motor vehicles to conduct official business for the State is within the jurisdiction of the State Fleet Administrator, Department of Budget and Fiscal Planning [now Department of Budget and Management “DBM”] ... and subject to policies issued by the Secretary____’ (Emphasis added.)
“We agree with the Comptroller that it is[:]
‘[C]lear what the “plain language” of COMAR 17.04.11.02B([l])(j) both does and does not do. It does not provide that the “entire” home to remote site commute constitutes work time. The language of the regulations does require, by its incorporation by reference of the Standard Travel Regulations, resort to the [S]tate [F]leet [P]olicies to determine what is to be considered work time.’
“The regulations set out in the ‘State Vehicle Fleet Policies and Procedures’ manual are incorporated by reference into COMAR 17.04.11.02B([l])(j). To conclude otherwise would defeat the ‘ordinary and natural meaning’ of the words of the statute____
“The Secretary of DBM, who administers both work time and travel reimbursement, has chosen to apply to travel time the policy applicable,for mileage, i.e., awarding compensation for travel time minus normal commuting time.”
Miller, 169 Md.App. at 348-51, 901 A.2d at 245-46.
We agree. For us to adopt petitioner’s position, would require us to read, “[i]n accordance with the Standard Travel Regulations under COMAR 23.02.01[,]” out of the regulation. The only logical interpretation of that language, used in this context, is that the regulation contemplates the application of the requirements of the Standard Travel Regulations. There is simply no other meaning that could apply under these circumstances.
Additionally, Judge Hollander pointed out below:
*285“Under [petitioner’s] analysis, an employee assigned to a remote work site that requires less travel time than the normal, daily commute would have a shorter work day, yet earn compensation in excess of a full day’s pay. Compensating employees for their entire travel time to a remote work site, without consideration of regular commute time, would lead to unjust enrichment of the employee, who would ordinarily have spent a portion of that time traveling to the regular work site. Commute time is not work time, and an employee who is on travel status is not entitled to compensation for either the mileage or the time that the employee regularly spends to commute. We decline to endorse a facially absurd result that is blatantly unfair to the taxpayers and results in a windfall to the employee.”
Miller, 169 Md.App. at 352, 901 A.2d at 247. We too decline to endorse a result that would require employees to be paid for non-work time just because they were at a remote work site when they would not be entitled to be paid for non-work time if they were assigned and traveling to their regular work site. Such a result is clearly illogical and absurd. The only logical interpretation for the inclusion in the regulation at issue here of the requirement that the Standard Travel Regulations apply, was to make the process of mileage and time compensation consistent. We affirm the Court of Special Appeals on the first issue presented.
B. Twenty Day Limitation on Filing of Grievances.
There is no authority for petitioner’s claim, by way of the grievance process, for an award of any compensation claimed prior to 20 days from the filing of her grievance. Petitioner is entitled to be compensated as provided in Deputy Comptroller Cordi’s November 12, 2003, “Management Decision.” In order to comply with § 12-303(b) of the State Personnel and Pensions Article, Deputy Comptroller Cordi correctly changed the Comptroller’s policy to allow a grievant to recover for acts occurring within 20 days prior to the filing of the grievance (as opposed to the previous, and incorrect, 30 day limitation). Thus, the Deputy Comptroller’s decision cor*286rectly allowed petitioner to be compensated for all acts occurring within the 20 days prior to her filing a grievance on August 7, 2003. We affirm the Court of Special Appeals on this second question as well.
IV. Conclusion
For the foregoing reasons, we hold that COMAR 17.04.11.02B(l)(j) does not entitle employees to compensation for all time spent traveling between home and a work site other than their assigned office and that § 12-203(b) of the State Personnel and Pensions Article requires a remedy to be limited to compensation for claims existing within 20 days prior to the initiation of a grievance.
JUDGMENT OF THE COURT OF SPECIAL APPEALS AFFIRMED. COSTS TO BE PAID BY PETITIONER.
BATTAGLIA, J., files a dissenting opinion joined by HARRELL, J.
. The regulation, which is the focus of this dispute, is found in Title 17 of the Code of Maryland Regulations, COMAR, subtitle 04, "Personnel Services and Benefits,” Chapter 11, “Leave,” section 02, "Workweek, Overtime and Compensatory Time,” subsection B, "Work Time." As relevant to the issues before this Court, COMAR 17.04.11.02B provides:
"B. Work Time.
(1) Work time includes time during which an employee:
(j) Travels between home and a work site other than the assigned office, in accordance with the Standard Travel Regulations under COMAR 23.02.01.”
The second regulation is COMAR 23.02.01.01, which provides in relevant part:
"A. Unless otherwise provided by law, these regulations apply to all travel for official business undertaken by ... employees....
C. These regulations do not apply:
*275(2) To State-owned, State-leased, or privately owned motor vehicles. Reimbursement to employees ... who use State-owned, State-leased, or privately owned motor vehicles to conduct official business for the State is within the jurisdiction of the State Fleet Administrator, Department of Budget and Fiscal Planning, and subject to policies issued by the Secretary of Budget and Fiscal Planning.’’ (Emphasis added.)
The applicable section of the provisions relating to the State Fleet Administrator, provides that:
"Reimbursement is based on the principle that the employee should be reimbursed for all official business mileage accumulated in a private vehicle which is beyond the normal round trip mileage incurred from the employee’s home to the permanently assigned office/work station and back home again.
(1) "A State employee who leaves home to conduct business without stopping at the assigned office may be reimbursed for all mileage directly connected with the business trip, which is in excess of the commute miles normally traveled, i.e., total official miles driven minus normal daily commute miles. In this situation, the driver has not driven his normal daily commute and therefore must subtract it from the total official miles driven.”
State of Maryland Department of Budget and Management Division of Policy Analysis, State Vehicle Fleet Policies and Procedures, § 5.01.05 (emphasis added) (Section 5.01.05 appears to be misnumbered. There are four subparagraphs in that section. There are two "(l)s,” a "(2),” and a “(4).” The present matter only concerns what should be, sequentially, "(2),” but in reality is the second “(1).”).
. Neither party has challenged before this Court the enactment of the various regulations at issue. Their validity is not at issue in this case.
. As far as we know, the time compensation at issue in this case involves financial compensation, or not, for the time expended. We need not address time for time compensation in this case. They may, or may not, be the same.
. At approximately the same time, the Comptroller formally changed the policy, eliminating the compensation condition that limited compensation to periods of time in excess of thirty minutes of an employee's normal commute. The new policy permitted compensation for any such period that was in excess of normal commute times.
. Section 12-203, in relevant part, provides:
“(b) Time limitations.—A grievance procedure must be initiated by an employee within 20 days after:
(1) the occurrence of the alleged act that is the basis of the grievance; or
(2) the employee first knew of or reasonably should have known of the alleged act that is the basis of the grievance.”
. By this point in the proceedings, the Deputy Comptroller had brought the pre-grievance period from 30 days down to 20 days in order to comply with the statute mentioned, supra. Additionally, the Office of the Comptroller had conceded that its former policy of not compensating for any time until an employee had exceeded the period of his normal commute by more than 30 minutes was incorrect and had changed the policy.
. Apparently, petitioner had elected to address the issue of the actual entitlement after a ruling by the ALJ, if that ruling was in her favor, by then submitting time sheets and the like to the Office of the Comptroller or other appropriate agency. This lack of evidence would impact one aspect of the ALJ's decision.
. Generally, in such procedural circumstances, it is the AU’s decision that is reviewed on appeal.
. There is no dispute of fact in the present case that is pertinent to our present inquiry. The issues before this Court involve pure questions of law. Moreover, we have been directed to no prior agency, or AU decisions, construing the statutes at issue here and their relationship with each other. There appears to be no longstanding, or any prior, position at the administrative level in respect to these statutes, thus, this appears to be a case of first impression. As such, in the present case, the decision of the agency below is owed less deference then that owed to longstanding positions of administrative bodies.
In cases such as that here presented, where the delegated ALJ takes a position exactly opposite of the position directly taken by the Agency, an issue can also arise as to what entity does a court owe deference (if any is due). This is a determination that will ultimately need to be decided. In light of our decision, it need not be done in the present case.
