    FRED C. PRILLAMAN OF MOHAN, ALEWELT, PRILLAMAN & ADAMI APPEARED ON
    BEHALF OF PETITIONER; and
     
    JOHN J. KIM OF THE ILLINOIS ENVIRONMENTAL PROTECTION AGENCY
    APPEARED ON BEHALF OF RESPONDENT.
     
    OPINION AND ORDER OF THE BOARD (by G.T. Girard):
     
    On May 7, 2003, Illinois Ayers Oil Co. (Ayers) filed a petition for review of a March 28,
    2003 decision by the Illinois Environmental Protection Agency (Agency) to modify the high
    priority corrective action plan (HPCAP) and budget for Ayers’ site in Beardstown, Cass County.
    A release from the three underground storage tanks (USTs) on the property was reported in 2000.
    Ayers’ appeal of the Agency’s decision to reduce Ayers’ previous HPCAP proposal for the same
    site is pending before the Board in Illinois Ayers Oil Company v. IEPA, PCB 03-70. In the
    instant case, Ayers challenges the Agency’s reduction in budget and in the number of soil
    borings.
     
    For the reasons below the Board reverses the Agency’s modification to the HPCAP with
    regards to the number of soil borings and corresponding costs for personnel, equipment, handling
    charges, and investigation. The Board affirms the Agency’s modifications for shipping,
    analytical costs and miscellaneous retail purchases.
     
    The Board will begin the discussion by describing the procedural background and
    addressing preliminary matters. Next, the Board will enumerate the facts relevant to the
    discussion of the issues. Then, the Board will set forth the statutory and regulatory background
    and the standard of review. Finally, the Board will summarize the arguments of the parties and
    elaborate on the Board’s reasoning for today’s decision.
     
    PROCEDURAL BACKGROUND
     
     
    On May 7, 2003, Ayers filed a petition for review (Pet.) of a March 28, 2003
    determination by the Agency that the HPCAP should be modified. On October 31, 2003, the

     
    2
    Agency filed the record in this matter (R.). Hearing was held before Board Hearing Officer
    Carol Sudman on January 7, 2004. On February 11, 2004, Ayers filed a brief (Pet. Br.) and on
    March 15, 2004, a reply (Reply). The Agency filed a brief (Ag. Br.) on March 10, 2004.
     
    PRELIMINARY MATTER
     
    On March 8, 2004, the Agency filed an “Objection to Hearing Officer’s Ruling and
    Motion to Strike” (Motion). The Agency moves the Board to overrule a hearing officer decision
    made at hearing on January 7, 2004. The hearing officer admitted, as exhibits, the depositions of
    Agency personnel over the objection of the Agency.
    See
    Tr. at 5-14. The Agency is asking that
    the Board strike the exhibits.
     
    The Board’s procedural rules provide that an “objection to a hearing officer ruling made
    at hearing . . . will be deemed waived if not filed within 14 days after the Board receives the
    hearing transcript.” 35 Ill. Adm. Code 101.502(b). The Board received the hearing transcript on
    January 12, 2004, 56 days before the Board received the Agency objection to the hearing
    officer’s ruling. The Board notes that this proceeding has a decision deadline of May 5, 2004,
    and the petitioner’s brief had already been filed when the motion was received. Further, the
    Agency’s brief was due on the day the Board received the motion and was actually received by
    the Board on March 10, 2004. Because of the time sensitive nature of this case, the Board denies
    the motion to strike as untimely. Further, if any error had occurred by the admission of the
    depositions, the Agency was given the opportunity at hearing to object to those deposition
    portions the Agency believed were not properly before the Board.
    See
    Tr. at 170-71, 212-13.
     
    FACTS
     
    Ayers is the owner of a gasoline service station located at 310 State Street, Beardstown,
    Cass County. Pet. at 1; R. at 1. The service station is located in close proximity to personal
    residences and other commercial buildings. R. at 16, Fig. 1. Ayers reported a release from three
    USTs on the site to the Illinois Emergency Management Agency in 2000. The site was assigned
    Incident No. 2000-2020 and was subsequently classified a high priority site because one or more
    groundwater quality standards was exceeded at the property boundary line. Pet. at 1; R. at 4, 83.
    Ayers hired CSD Environmental Services, Inc. (CSD Environmental) to perform remediation at
    the site. Pet. Exh. 18.
     
    On June 20, 2002, CSD Environmental on behalf of Ayers submitted a HPCAP to the
    Agency that was rejected. Pet. Exh. 6 (A). Ayers appealed the Agency’s decision, and that
    appeal is currently pending before the Board.
    See
    Illinois Ayers Oil Company v. IEPA, PCB 03-
    70. After the appeal in PCB 03-70 was filed, Ayers and the Agency met to discuss issues raised
    in the Agency’s first HPCAP rejection, including the use of the direct push groundwater
    sampling. Tr. at 69.
     
    Mr. Joseph Truesdale is a professional engineer employed by CSD Environmental and
    has been involved in preparing the HPCAP for Ayers. Tr. at 25-26. Mr. Truesdale attended the
    meetings with the Agency to discuss this Beardstown project and another CSD Environmental
    project in another town. Tr. at 26. Mr. Truesdale testified that during those meetings he

     
    3
    provided to the Agency a copy of an Agency fact sheet that indicates that direct push technology
    is acceptable for groundwater and soil monitoring. Tr. at 33-34; Pet.Exh. 9. Mr. Truesdale
    attended a second meeting with Agency employees including Carol Hawbaker, who reviews
    corrective action plans and budgets, to discuss the Ayers site. Tr. at 29. As a result of the
    meetings, Ayers’ revised HPCAP proposed using the direct push method for both groundwater
    and soil sampling. Tr. at 35.
     
    Also at the meeting Mr. Truesdale discussed with both Ms. Hawbaker and Mr. Harry
    Chappel, Ms. Hawbaker’s supervisor, the production time for direct push boring and the location
    of the borings. Tr. at 37-38. Mr. Truesdale indicated that CSD Environmental had performed
    field tests to establish the average time to conduct direct push borings. Tr. at 40. Mr. Truesdale
    testified that the testing confirms the hours proposed in the revised HPCAP are necessary given
    the geologic conditions at the site. Tr. at 40-41. Mr. Truesdale stated that at the meeting he
    explained that the placement of some of the borings was needed to evaluate potential source
    contaminants. Tr. at 42. Mr. Truesdale explained the proposed locations of some of the other
    borings were based on the groundwater transport modeling, and some of the borings were
    proposed to evaluate lateral spread of the plume. Tr. at 43. Mr. Truesdale testified that as a
    result of discussions with the Agency personnel, the professional engineer hours were reduced
    from the original application to the revised application. Tr. at 38.
     
    On December 4, 2002, Ayers filed the revised HPCAP with the Agency that is the subject
    of this appeal. Pet. at 1; R. at 1. The cover letter for the revised HPCAP stated that the revised
    plan had been amended in response to the meetings with the Agency. R. at 1. More specifically,
    the cover letter indicated that the HPCAP was revised to include “only work associated with
    defining the extent of BTEX contamination.” R. at 1. The cover letter stated that the unit rates
    had been maintained from the prior submission.
    Id
    .
     
    The HPCAP stated, the “intention of this phase of corrective action process is to better
    define the extent and relative distribution of petroleum contamination in order to develop an
    effective future groundwater monitoring program” and “to evaluate potential future remediation
    strategies.” R. at 11. The HPCAP identified that “[g]iven the relatively permeable geologic
    materials encountered at the site, and since the contamination is primarily associated with the
    groundwater, in-situ bioremediation and/or groundwater pump and treat would appear to be
    viable active remediation strategies.” R. at 11.
     
    To this end, the HPCAP proposed 6 on-site and 7 off-site locations for direct-push
    borings. R. at 6. Two separate borings would need to be taken, one for soil and one for
    groundwater at each of the proposed locations. Tr. at 105. Originally, all soil and groundwater
    borings were to be analyzed for BTEX, but Mr. Truesdale indicated that during meetings with
    the Agency, the Agency objected to chemical analysis being performed on all the soil borings.
    Tr. at 104. In response, Ayers reduced the number of soil borings that would be chemically
    tested. Tr. at 104. Instead, the HPCAP proposed that all 13 direct-push soil borings would be
    logged and screened, but soil samples from only 3 of the soil borings would be collected for
    laboratory analysis. R. at 6, Tr. at 104. Separate direct-push groundwater samples would be
    collected from all 13 of the proposed direct-push boring locations. R. at 6. All soil and
    groundwater samples collected for laboratory analysis would be analyzed for BTEX. R. at 6.

     
    4
     
    Truesdale stated in his testimony that although only 3 soil borings would be analyzed for
    BTEX, all 13 soil borings were intended to be logged. Tr. at 49, 50. Truesdale explained how
    logging each soil boring would be used to determine the significant physical features of the site
    and surrounding area that may affect contaminant transport and risk to human health and safety
    and the environment. Tr. at 50.
     
    Truesdale testified that the site classification indicated that the regional geology was an
    “AX type stratigraphy which was defined by Berg as modern river alluvium consisting of a
    mixture of gravel, sand and silt along streams variable in composition and thickness.” Tr. at 71,
    R. at 8. The HPCAP described that materials beneath the site present a high potential for both
    surface and groundwater contamination. R. at 8. The HPCAP stated, “[h]ydraulic
    conductivities, on the order of 1 x 10 –3, make these materials an excellent medium for
    contaminant transport.” R. at 8. Truesdale elaborated in his testimony that this is essentially the
    definition of a migration pathway. Tr. at 104. Truesdale continued, “[s]ince the soils at the site
    were specified as variable in composition and thickness without quantifying that variability
    across the potential limits of the plume, there would be no way to fully evaluate those identified
    natural migration pathways or, as a matter of fact, would not be able to identify those potential
    natural migration pathways on off site locations, whatsoever.” Tr. at 72.
     
    To quantify that variability, Truesdale elaborated that CSD Environmental “proposed to
    log the soil samples encountered at each boring in order to identify and verify locations of
    potential natural migration pathways that were encountered and identified during site
    classification and to classify the soils in accordance with ASTM standards in order to verify that
    the position stated in the site classification report was, in fact, accurate at all locations, including
    off site properties, as it relates to the heterogeneities and nonhomogenous nature of the soil
    encountered at the site during site classification.” Tr. at 48.
     
    In her deposition, Hawbaker agreed that if the previous site classification found some
    layers that seemed to be heterogeneous in the site, then perhaps some soils investigation would
    be needed as part of a Phase 1 Plan. Pet. Exh. 2 at 22. However, Hawbaker felt this was not the
    case here.
    Id
    . Hawbaker stated, “[r]egional soil geology has been proven to be uniform at the
    site.”
    Id
    .
     
    The budget summary and total included in the HPCAP proposed:
     
    $12,666.60 for investigation
    $3,010.00 for analytical costs,
    $32,514.00 for personnel costs
    $1,599.60 for equipment costs
    $863.00 for field purchases
    $1,714.76 for handling charges. R. at 67
     
    The investigation costs were based on 520 feet of total soil and groundwater borings and 50
    hours of work. R. at 68. The analytical costs include $2,100 for BTEX analysis of groundwater
    sampling. R. at 70-71. The personnel costs include a professional engineer, professional

     
    5
    geologist, project engineer, staff geologist and engineering tech. R. at 72. Equipment totals
    include use of equipment for five days of work. R. at 74. Field purchase include UPS shipping,
    peristaltic groundwater sampling pump, disposable tubes and miscellaneous retail purchases such
    as ice and film. R. at 76.
     
    On March 28, 2003, the Agency issued a decision letter with modifications to the HPCAP
    submitted by Ayers. R. at 86. Specifically, the Agency found that 10 of the 13 proposed direct
    push soil borings were in excess of the minimum requirements of Title XVI of the Act (415
    ILCS 5/Title XVI (2002)) because the soils were previously classified. R. 86-87. Specifically,
    the denial letter states:
     
    The required modification(s) is/are as follows: The plan includes 13 additional
    direct push soil borings to better define and evaluate the extent and relative
    distribution of petroleum contaminants in the subsurface. The plan proposes that
    only 3 of these direct push soil borings will be sampled for BTEX concentrations.
    Therefore, it appears as though the remaining 10 direct push soil borings would be
    to classify and log the subsurface soils in connection with the 13 direct push
    groundwater sampling probes to define groundwater extent. For the purposes of
    reimbursement, as the soils were previously classified at the site during site
    classification activities, the additional 10 direct push soil borings are in excess of
    those necessary to meet the requirements of Title XVI of the Act for corrective
    action investigation; cost for such activities are not reimbursable (Section 57.5(a)
    of the Act and 35 IAC [sic] 732.606(o). R. at 86-87.
     
    The budget proposed by Ayers was reduced by the following amounts:
     
    $8,910.72 and $108.00 for Investigation costs
    $490.00 for Analysis Costs
    $18,450.00 for Personnel Costs
    $849.30 for Equipment Costs
    $36.00 for Camera
    $150.00 for USP [sic] sample shipping
    $50.00 for Miscellaneous Retail Purchases
    $270.00 for Peristaltic Pump
    $979.17 for handling charges. R. at 90-92.
     
    Mr. Truesdale and Ms. Cindy Davis, owner of CSD Environmental, testified on behalf of
    Ayers at the Board’s hearing on November 25, 2003. In addition to the testimony discussed
    above, Mr. Truesdale also described the direct push sample method. Tr. at 44-46. Mr. Truesdale
    indicated that there is a difference in the amount of time taken to collect only soil samples and
    the time to collect groundwater samples. Tr. at 45. Mr. Truesdale stated that the HPCAP was
    clear that Ayers would be using the direct push method to do both soil and groundwater
    sampling. Tr. at 46. Mr. Truesdale indicated that some time is needed when collecting
    groundwater samples to allow groundwater to collect. Tr. at 46-47. Mr. Truesdale stated that he
    included that time in the estimates of hours for work at the site.
    Id
    .
     

     
    6
    Mr. Truesdale also elaborated on how the soil samples would be examined and used. Tr.
    at 47-49. Mr. Truesdale testified that the information was all included in the HPCAP.
    Id
    . Mr.
    Truesdale testified that each of the line items on the budget were necessary to meet the
    requirements of the Act and Board regulations. Tr. at 52-64. Mr. Truesdale testified that the
    investigation of the site was prepared in accordance with a United States Environmental
    Protection Agency (USEPA) guidance document. Tr. at 65. Mr. Truesdale provided the Agency
    with a copy of the USEPA guidance document
    Expedited Site Assessment Tools for
    Underground Storage Tank Sites
    , USEPA (March 1997). Tr. at 65-66; Pet. Exh. 10.
     
    Ms. Davis testified as to her experience in the field and described her company. Tr. at
    126-34. Ms. Davis founded the firm in 1992. Tr. at 127. Prior to founding CSD Environmental,
    Ms. Davis worked for the Agency. Tr. at 128-29. Ms. Davis described how she developed the
    professional engineer rate. Tr. at 134-35. Ms. Davis indicated that the rate is based on the
    amount she actually pays the engineer and uses a standard engineering profit multiplier. Tr. at
    134. Ms. Davis stated that she pays her employees about the same amount as the Agency. Tr. at
    135. Ms. Davis indicated that the hourly rates for both the professional engineer and project
    engineer have been previously approved by the Agency. Tr. at 137. Ms. Davis also purchases a
    survey every year which does not include underground storage tank clean-ups but does indicate
    that the standard billing rate for a professional engineer at other projects is $132 to $155 per
    hour. Tr. at 140.
     
    Ms. Hawbaker and Mr. Brian Bauer testified at hearing on behalf of the Agency. Ms.
    Hawbaker testified that she has been with the Agency since September 2000 and has reviewed
    over 200 sites, including approximately 70 high priority sites. Tr. at 171. Ms. Hawbaker
    indicated that she used the Agency rate sheet in making modifications to the budget. Tr. at 172.
    Ms. Hawbaker testified that the rate sheet is useful because the rate sheet helps Agency
    reviewers determine the guidelines and basis of charges being made. Tr. at 185.
     
    In reference to the Agency modifications of the HPCAP, Ms. Hawbaker testified that 10
    of the 13 soil borings, in her opinion, were not to be used to define the extent of contamination
    for soil. Tr. at 176. Ms. Hawbaker relied on a statement in the budget (R. at 68) for her opinion.
    Tr. at 177. On cross-examination, Ms. Hawbaker testified that the type of soil at the site would
    not affect her opinion on the number of soil borings needed. Tr. at 202.
     
    Ms. Hawbaker further stated that the reduction for direct push borings were taken based
    on a discussion with her unit manager (Mr. Harry Chappel). Tr. at 179. Ms. Hawbaker testified
    that the costs for direct push investigation, drilling labor, utility truck, and job trailer were not
    reasonable as submitted based on the rate sheet so budget reductions were made. Tr. at 180-81.
    Ms. Hawbaker testified that “some” of the budget reductions were based on comparison with the
    rate sheet. Tr. at 182-83. Ms. Hawbaker delineated which rates were cut based on the rate sheet.
    Tr. at 183-85, 186-88.
     
    Mr. Bauer testified that he is a project manager with the Agency also supervised by Mr.
    Chappel. Pet. Exh.4 at 2. Mr. Bauer testified that the maximum dollar amount or rate on the
    Agency rate sheet is a rate the project manager could approve without further information. Tr. at
    215. Mr. Bauer testified that his involvement with the rate sheet included drafting the memo and

     
    7
    all of the attachments for Mr. Doug Clay, and “daily gathering for the rates.” Tr. at 217, Pet.
    Exh. 4 at. Exh. 3. Mr. Bauer testified that if a rate was received by an Agency reviewer that was
    higher than the one listed on the rate sheet, the higher rate would be modified or denied. Tr. at
    217. Mr. Bauer indicated that a higher rate could be approved if additional information were
    provided.
    Id
    .
     
    Mr. Bauer testified that the rate sheet was developed using the average of a sample
    collected and adding one standard deviation. Tr. at 219. Mr. Bauer stated that the practical
    result of using a formula of an average plus one standard deviation in terms of percentage of
    costs expected at or below the maximum figure would be 84%. Tr. at 220. Mr. Bauer indicated
    that determination of rates on a side-by-side basis would be impossible. Tr. a 221. Mr. Bauer
    concedes that the rate sheet is not provided to the public and is kept “secret” and internal to the
    Agency. Tr. at 225-26.
     
    STATUTORY AND REGULATORY BACKGROUND
     
    Section 57.7 of the Act (415 ILCS 5/57.7 (2002)) sets forth the requirements for site
    investigation and corrective action at a site where a leaking underground storage tank has been
    removed. Section 57.7(b)(2) requires that the owner or operator submit to the Agency, a
    corrective action plan designed to “mitigate any threat to human health, human safety, or the
    environment resulting from the underground storage tank release.” 415 ILCS 5/57.7(b)(2)
    (2002). Section 57.7(b)(3) requires that owners or operators “intending to seek payment from
    the Fund” must submit a budget to the Agency. 415 ILCS 5/57.7(b)(3) (2002).
     
    Section 57.7(c) sets forth the provision for Agency review and approval and subsection
    (c)(3) provides in part:
     
    In approving a plan . . . the Agency shall determine, by a procedure promulgated
    by the Board under Section 57.14, that the costs associated with the plan are
    reasonable, will be incurred in the performance of site investigation or corrective
    action, and will not be used for site investigation or corrective action activities in
    excess of those required to meet the minimums requirements of this Title. 415
    ILCS 5/57.7(c)(3) (2002).
     
    The Board’s rules promulgated pursuant to Section 57.7(c)(3) are at 35 Ill. Adm. Code
    732.Subpart E. Section 732.501 provides in part that “all plans or reports shall be made on forms
    prescribed and provided by the Agency.” 35 Ill. Adm. Code 732.501. Section 732.504(a)(1)
    requires the Agency to perform a “full review” on high priority corrective action plans and
    budgets. 35 Ill. Adm. Code 732.504(a)(1). Section 732.502 defines the scope of a full technical
    and financial review and provides, in part:
     
    A full review may include any or all technical or financial information, or both,
    relied upon by the owner or operator or Licensed Professional Engineer in
    developing the plan or report selected for review. The full review also may
    include the review of any other plans or reports submitted in conjunction with the
    site. 35 Ill. Adm. Code 732.503(a).

     
    8
     
    Section 732.505 provides the standards to be used in reviewing plans and budgets.
    Section 732.505(a) provides, in part:
     
    The overall goal of the technical review for plans shall be to determine if the plan is
    sufficient to satisfy the requirements of the Act and regulations and has been prepared in
    accordance with generally accepted engineering practices. The overall goal of the
    technical review for reports shall be to determine if the plan has been fully implemented
    in accordance with generally accepted engineering practices, if the conclusions are
    consistent with the information obtained while implementing the plan, and if the
    requirements of the Act and regulations have been satisfied. 35 Ill. Adm. Code
    732.505(a).
     
    Section 732.505(c) provides, in part:
     
    The overall goal of the financial review shall be to assure that costs associated
    with materials, activities and services shall be reasonable, shall be consistent with
    the associated technical plan, shall be incurred in the performance of corrective
    action activities, and shall not be used for corrective action activities in excess of
    those necessary to meet the minimum requirements of the Act and regulations. 35
    Ill. Adm. Code 732.505(c).
     
    STANDARD OF REVIEW
     
    Pursuant to Sections 57.7(c) and 57.8(i) of the Act (415 ILCS 5/57.7(c) and 57.8(i)
    (2002)), an applicant may appeal an Agency to “disapprove or modify a plan or report” to the
    Board under the provisions of Section 40 of the Act (415 ILCS 5/40 (2002)). Under Section 40
    of the Act (415 ILCS 5/40 (2002)), the Board’s standard of review is whether the application as
    submitted to the Agency would not violate the Act and Board regulations. Browning Ferris
    Industries of Illinois v. PCB, 179 Ill. App. 3d 598, 534 N.E.2d 616 (2nd Dist. 1989). Therefore,
    the Board must decide whether or not the application as submitted to the Agency, demonstrates
    compliance with the Act and Board regulations. Kathe’s Auto Service Center v. IEPA, PCB 96-
    102 (Aug. 1, 1996). Further, the Agency’s denial letter frames the issue on appeal.
    Id
    . Finally,
    the burden of proof is on the owner or operator, who must provide an accounting of all costs.
    Platolene 500, Inc. v. IEPA, PCB 92-9 (May 7, 1992); Ted Harrison v. IEPA, PCB 99-127
    (July 24, 2003).
     
    DISCUSSION
     
    On appeal, Ayers raises three general issues in the opening brief. First, Ayers takes issue
    with the Agency’s use of the rate sheet to establish reasonable costs. Pet. Br. at 8. Second,
    Ayers challenges the technical review of the corrective action plan. Pet. Br. at 18. Third, Ayers
    challenges the financial review. Pet. Br. at 27. In the reply, Ayers also takes issue with the
    Agency’s characterization of the burden of proof and the scope of the Board’s review. The
    following discussion will first summarize the arguments by Ayers. Then, the Board will

     
    9
    summarize the Agency’s arguments. Then the Board will elaborate on the Board’s decision
    including the reasoning supporting the Board’s decision.

    Ayers argues that the rate sheet and all testimony based on the rate sheet should be
    stricken for one of two alternative reasons. First, Ayers argues that the rate sheet is invalid as a
    de facto
    rule. Pet. Br. at 9. In the alternative, Ayers asserts that the Agency’s refusal to disclose
    the basis for the rate sheet prohibits the use of the rate sheet as evidence. Pet. Br. at 14. The
    Board will summarize in Ayers’ position on these two assertions.
     
    Next the Board will summarize the Agency’s response that the use of the Agency’s
    “internal guidance” was proper. Then the Board will summarize Ayers’ reply.
     
    Ayers Arguments
     
     
    The Rate Sheet is a Rule.
    Ayers argues that the Agency’s rate sheet is an
    unpromulgated rule that violates the Illinois Administrative Procedure Act (APA) (5 ILCS 100/1
    et seq
    . (2002)). Pet. Br. at 9. Ayers points out that a rule is defined in the APA as “each agency
    statement of general applicability that implements, applies, interprets, or prescribes law or policy
    . . .” (5 ILCS 100/1-70 (2002)). Pet. Br. at 9. Ayers maintains that the Agency’s rate sheet
    implements an Agency policy establishing the “maximum allowable cost” for many activities
    performed as a part of corrective action. Pet. Br. 9.
     
    Ayers notes that Ms. Hawbaker indicated in deposition testimony that she and other
    reviewers are required to use the rate sheet as a matter of practice (Pet. Exh. 2 at 70). Pet. Br. at
    10. Ms Hawbaker also testified that she did not deviate from the rate sheet nor did she look at
    any information upon which the rate sheet was based. Pet. Br. at 10, citing Tr. at 205. Mr.
    Bauer testified that the rate sheet was intended to promote consistency and speed of review. Pet.
    Br. at 10, citing Tr. at 221. Ayers argues that these “objectives are laudable” however, the rate
    sheet establishes consistency by creating a “standard of general applicability” that implements
    requirements of the Act. Pet. Br. at 10.
     
    To support the argument, Ayers cites Senn Park Nursing Center v. Miller, 104 Ill. 2d 169
    (1984). In Senn Park, the Illinois Supreme Court ruled that an agency policy for calculating
    reimbursable costs under Medicare is a rule of general applicability subject to the APA. Pet. Br.
    at 10, citing Senn Park, 104 Ill. 2d 169, 178. Ayers acknowledges that certain exceptions to the
    APA exist; however, for the rate sheet to be exempt from the APA, the rate sheet must relate to
    the internal management of the Agency and not effect private rights or procedures available to
    persons outside the Agency. Pet. Br. at 10-11, citing 5 ILCS 100/1-70(i) (2002). In this
    instance, Ayers asserts that the sole purpose of the rate sheet is to decide how much money
    people outside the Agency will be paid. Pet. Br. 11. Therefore, Ayers argues that the APA
    exception does not apply.
    Id
    .
     
    Furthermore, Ayers asserts that the record is clear that the rate sheet is not merely
    “guidance” for Agency personnel. Pet. Br. at 11. Ayers relies on the testimony of Mr. Bauer to

     
    10
    bolster the argument.
    Id
    . Ayers cites to testimony that if a cost were higher than the maximum
    on the rate sheet, the cost would be modified down or disapproved. Pet. Br. at 11, citing Tr. at
    217. Ayers asserts that Mr. Bauer and Ms. Hawbaker both support this use of the rate sheet. Pet.
    Br. at 11.
     
    Ayers maintains that even if the Agency allows project managers discretion in applying
    the rates on the rate sheet, the rate sheet is still an improperly promulgated rule. Pet. Br. at 12.
    Ayers argues that the rate sheet is not issued on a case-by-case basis and the rate sheet is not a
    statement specifically about Ayers.
    Id
    . The rate sheet applies to all budget and reimbursement
    claims and signifies that the Agency “has moved away” from adjudicatory decision making in
    UST reimbursement decisions. Pet. Br. at 12.
     
     
    The Rate Sheet is Not Proper Evidence.
    Ayers argues that the Agency’s refusal to
    disclose the underlying data used in developing the rate sheet renders the rate sheet improper.
    Pet. Br. at 14-15. Ayers cites Wirtz v. Baldor Electric Co., 337 F.2d 518 (D.C. Cir. 1964) and 2
    Am.Jur. 2d, Administrative Law § 330 to support this proposition. Pet. Br. at 14-15. Ayers
    asserts that in Wirtz the court found that the government could not support a decision based upon
    summaries of evidence that the government refused to disclose to the opposing party. Pet. Br. at
    14-15. Ayers indicates that the court found that summary evidence may only be used if the
    supporting documents are at least made available to the opposing party.
    Id
    . Ayers argues that
    the facts of this case are analogous to Wirtz and the Agency should not be allowed to rely on the
    rate sheet.
    Id
    .
     
    Agency Arguments
     
    The Agency argues that the use of the rate sheet is appropriate. Ag. Br. at 6. First the
    Agency maintains that the rate sheet is not a
    de facto
    rule. Ag. Br. at 6. Second the Agency
    asserts that the Agency merely handled the information regarding the rate sheet in the manner
    specified in Board and hearing officer orders during discovery. Ag. Br. at 9.
     
     
    Rate Sheet is Not a
    De Facto
    Rule.
    The Agency asserts that the facts surrounding the
    Agency’s rate sheet are distinguishable from those in Senn Park and thus Senn Park is not
    applicable here. Ag. Br. at 6. The Agency argues that in Senn Park the state agency was
    amending a procedure for calculating an inflation factor used when determining rates of
    reimbursement for nursing home facilities. Ag. Br. at 6, citing Senn Park at 104 Ill. 2d 169, 176-
    77. In this case the internal guidance is not an amendment of an existing plan, argues the
    Agency, but rather the Agency’s means of implementing a requirement in the Board’s
    regulations. Ag. Br. at 6.
     
    The Agency argues that the facts surrounding the rate sheet are more analogous to those
    in Donnelly v. Edgar, 117 Ill. 2d 59, 509 N.E.2d 1015 (1987) and Kaufman Grain Company v.
    Department of Agriculture, 179 Ill. App. 3d 1040, 534 N.E.2d 1259 (4th Dist. 1988). In
    Donnelly, the Illinois Supreme Court determined that statements concerning only internal
    management of an agency and not affecting private rights are not rules subject to the APA. Ag.
    Br. at 7. In Kaufman Grain, the appellate court repeated the “sentiment” in Donnelley and stated
    that not all statements of agency policy must be announced by means of a rule.
    Id
    .

     
    11
     
    The Agency also relies on Highland Park Convalescent Center v. Illinois Health Facility
    Planning Board, 217 Ill. App. 3d 1088, 578 N.E.2d 92 (1st Dist. 1991). In that case the court
    reviewed the methodology used by the state agency to make determinations. Ag. Br. at 8. The
    court found the methodology was not a rule as contemplated by the APA.
    Id
    .
     
    The Agency argues that the rate sheet is an internal document expressly used in the
    promotion of consistency in decisions. Ag. Br. at 8. The Agency asserts that the document is
    internal to the Agency and does not affect private rights.
    Id
    . The Agency argues that the means
    by which the Agency makes the underground storage tank decisions is subject to appeal and
    adjudication is an appropriate means to establish agency policy. Ag. Br. at 8-9.
     
     
    The Agency Treated the Rate Sheet Per the Board’s Orders.
    The Agency responds to
    Ayers that the Agency was following Board and hearing officer orders issued during the
    discovery process regarding the rate sheet. Ag. Br. at 9. The Agency asserts that the Agency
    should not be penalized for following those orders. Ag. Br. at 10.
     
     
    Ayers’ Reply
     
     
    Ayers concedes that not all statements of Agency policy must be announced by means of
    a promulgated rule. Reply at 3. Ayers further concedes that the case law allows an agency to
    interpret statutory provisions to a particular set of facts in adjudicated cases.
    Id
    . However,
    Ayers asserts that published rules are required for each agency statement of general applicability
    that implements, applies, interprets, or prescribes law or policy.
    Id
    . Ayers claims the rate sheet
    is such statement of general applicability. Reply at 3-5.
     
    Ayers states that they are not challenging the Agency’s choice of adjudication or
    rulemaking. Reply at 4. Instead, Ayers believes the Agency must accept the consequences of
    the choices.
    Id
    . Ayers argues that the Agency can choose to adopt a generalized standard
    through rulemaking or the Agency cannot rely on “secret ‘internal guidance’” in making decision
    on reimbursement.
    Id
    .
     
    Ayers argues that rates that can be charged by outside contractors are clearly not matters
    of internal management. Reply at 6. Furthermore, Ayers argues that the legislature in the APA
    had clearly directed any agency involved in rate making to do so through promulgated rules.
    Reply at 6, citing 5 ILCS 100/5-25. Thus, Ayers maintains that even if the Board were to
    determine that the rate sheet was solely an internal matter, the APA still requires the adoption of
    the rate sheet through rulemaking.
    Id
    .
     
    Ayers also replies to the Agency argument that the Agency was following Board orders
    in not disclosing information regarding the rate sheet. Reply at 6. Ayers argues that the Agency
    cannot “hide behind the Board’s discovery order” to defend the Agency’s refusal to disclose
    rates relied upon by the Agency in determining the rates.
    Id
    . Ayers asserts that the Agency
    argument to the Board on the discovery issue was that the disclosure of the information would be
    premature until the hearing.
    Id
    . Ayers argues that the Agency had the hearing but the question
    remains as to whether the rate sheet is competent evidence of anything.

    Technical Review
     
    The Board will first summarize the arguments in Ayers’ brief. Next the Board will
    delineate the Agency’s response. Then the Board will summarize Ayers’ reply.
     
    Ayers Arguments
     
    Ayers argues that all 13 soil borings proposed as a part of the HPCAP are necessary to
    meet the minimum requirements of the Act. Pet. Br. at 18. Ayers states that the Board’s rules
    acknowledge that corrective action may include additional soil and groundwater examination.
    Pet. Br. at 18, citing 35 Ill. Adm. Code 732.404(e). In this instance, Ayers claims that additional
    investigation was deemed necessary by the project’s engineer because of information learned
    during soil classification. Pet. Br. at 18.
     
    Ayers argues that the record supports additional investigation because the soil conditions
    pose a high potential for surface and groundwater contamination. Pet. Br. at 19, citing R. at 8.
    The corrective action plan included a diagram of the stratigraphic cross section along with a
    discussion of actual soil conditions. Pet. Br. at 19, citing R. at 19. Ayers maintains that the Act
    requires investigation and remediation of natural migration pathways and there was still
    inadequate information to determine the extent of contamination and of threats to human health
    and the environment. Pet. Br. at 19.
     
    Ayers relies on Mr. Truesdale’s testimony that the 13 soil borings proposed are the
    minimum necessary to achieve the Act’s goals and in fact more soil borings may be necessary.
    Pet. Br. at 21, citing Tr. at 72. Even though chemical analysis will only be performed on three
    soil borings, Ayers argues that the qualitative information concerning soil conditions and
    characteristics of potential migration pathway can be established. Pet. Br. at 22. Ayers also
    argues that the approach to the investigation is consistent with USEPA guidance and generally
    accepted engineering practices. Pet. Br. at 21. Ayers asserts that the initial investigation
    identified soil conditions which make knowing the extent of contamination difficult and
    established a need for further investigation. Pet. Br. at 22. The corrective action plan explained
    this need.
    Id
    . Therefore, Ayers argues the Agency mistakenly reduced the number of soil
    borings at the site. Pet. Br. at 26.
     
    Agency Arguments
     
    The Agency asserts that Ayers has not demonstrated that the HPCAP as provided to the
    Agency was necessary to meet the requirements of the Act. Ag. Br. at 10. The Agency argues
    that the information and documentation with the corrective action and budget do not support the
    use of 13 soil borings.
    Id
    . The Agency maintains that the record contains no statement that the
    10 direct push soil borings disallowed by the Agency would be tied to investigation of natural
    migration pathways.
    Id
    . The only direct reference, according to the Agency, is a reference that
    the locations will be probed and sampled “in accordance with 35 Ill. Adm. Code 732.308(a).”
    Ag. Br. at 11. The Agency argues that Section 732.308 relates to soil classification and soil
    classification had already occurred at this site. Therefore, the Agency’s conclusion that the 10

     
    13
    soil borings were related to site classification is supported by the record according to the Agency.
    Pet. Br. at 11.
     
    Ayers’ Reply
     
    Ayers asserts that, missing from the Agency’s justification of the technical review
    performed by the Agency, is the reviewer’s failure to read the corrective action plan. Reply at 7.
    Ayers maintains that the entire purpose of the investigation plan was clearly set forth.
    Id
    . Ayers
    cites to the record for support that the additional soil borings were needed.
    Id
    , R. at 1 and 6.
    Ayers argues that the Agency’s denial letter frames the issues on appeal and the Agency
    reviewer testified that the number of soil borings was excessive because of her mistaken
    understanding of local soil conditions. Reply at 7-8.
     
    Financial Review
     
    The Board will first summarize the arguments in Ayers’ brief. Next the Board will
    delineate the Agency’s response. Then the Board will summarize Ayers’ reply.
     
    Ayers Arguments
     
    Ayers asserts that the Agency erroneously reduced the investigation costs. Pet. Br. at 27.
    Specifically, Ayers argues that the reduction in the number of soil borings was an incorrect
    decision based on the technical record so the corresponding reduction in costs should be restored.
    Id
    . Further, Ayers argues that the Agency incorrectly estimated the time necessary to do direct
    push soil borings. Pet. Br. at 27. Therefore, the corresponding reduction in costs for boring
    should be restored. Pet. Br. at 30. The remaining investigation charges should also be restored
    because of the restoration of these costs. Pet. Br. at 30.
     
    Ayers also argues that all the reductions taken by the Agency based on the rate sheet
    should be restored. Pet. Br. at 31-36. The costs provided by Ayers are appropriate and Ayers
    argues that the only basis for reduction was the rate sheet.
    Id
    . Ayers also takes issue with hours
    of work, which were reduced for certain job titles.
    Id
    . Ayers asserts that the record also supports
    restoration of those hours.
     
    Ayers also argues for restoration of equipment costs because the costs are based on a
    reasonable number of days worked and reasonable costs. Ayers offers the testimony of Mr.
    Truesdale to support this argument. Pet. Br. at 36-38. Finally, Ayers asks that handling charges
    also be restored based on the restoration of other costs. Pet. Br. at 38.
     
    Agency’s arguments
     
    The Agency argues that there were essentially four components to the Agency’s decision
    to reduce costs on the budget. Ag. Br. at 11. Those four components are: the reduction of 13
    soil borings to 10; the reduction of five days time for investigation to two days time; the
    reduction of allowed hours; reduction of allowed rates/costs.
    Id
    . The Agency argues that on

     
    14
    each point Ayers has failed to sustain the burden of proof and the Agency’s decision was
    reasonable and appropriate. Ag. Br. at 11-12.
     
    The Agency relies on the prior argument that the reduction in soil borings was correct.
    Therefore, the Agency argues the corresponding reduction in investigation time was appropriate.
    Ag. Br. at 12. The Agency asserts that there is no supporting documentation for the days and
    hours found in the budget and as a result the reviewer sought advice from her supervisor. Ag.
    Br. at 12. The Agency reviewer appropriately relied on the experienced estimate to determine
    that the hours were not reasonable and reduced the hours accordingly.
    Id
    .
     
    The Agency also argues that there is not documentation for the rates and costs associated
    with the tasks in the budget. Ag. Br. at 13. The explanation and testimony at hearing by Ms.
    Davis and Mr. Truesdale was not information provided in the HPCAP and therefore was not
    before the Agency when the Agency made the decision, according to the Agency. Pet. Br. at 13.
     
    Ayers’ Reply
     
    In the reply, Ayers expresses frustration that the budget was completed using the forms
    provided by the Agency and on those forms the Agency sought a breakdown for drilling costs on
    the basis of feet to be bored. Reply at 8, citing R. at 68. However, Ayers argues that the rate
    sheet calculated the costs on a per-day basis, and as a result the reviewer asked her supervisor
    how many direct push soil borings could be done in a day. Reply at 8-9. Ayers asserts that the
    supervisor’s answer did not take into account the site-specific requirements of the Ayers site and
    therefore the decision was based on the Agency’s failure to consider the information before the
    Agency. Reply at 9.
     
    As to the remaining reductions, Ayers argues that the Agency’s response that the
    reductions were made “based on past experience of” Agency staff must be rejected. Reply at 9.
    Ayers argues that a single member of the staff who has only been with the Agency since 2000
    made the reductions.
    Id
    . Ayers maintains that the Agency, in fact, relied on the rate sheet as a
    substitute for experience. Reply at 10.
     
    Burden of Proof and Board Review
     
    Ayers concedes that the parties generally cite the same legal authorities setting forth the
    burden of proof and the scope of the Board’s review. However, Ayers argues that the Agency
    “largely discards these standards in” the Agency argument. Reply at 1. Ayers argues that the
    denial letter defines the issues on appeal, but the Agency makes no reference to the denial letter
    in the response brief.
    Id
    . Ayers points to the Act and states that the denial letter should contain
    specific reasons why the Act and the regulations require denial or modification. Reply at 1,
    citing 415 ILCS 5/57.7(c)(4) (2002). Ayers asserts that the Agency hopes to prevail on grounds
    other than those stated in the denial letter, which is that 10 soil borings were excessive. Reply at
    1-2. Rather than justify the Agency’s decision, Ayers asserts that the Agency argues that the
    HPCAP had insufficient information to know the purposes of the soil borings. Reply at 2.
     

     
    15
    Ayers argues that the Agency would not only ignore the denial reasons in the denial
    letter, but also have the Board ignore all evidence not contained in the HPCAP. Reply at 2.
    Ayers maintains that the hearing before the Board is the first opportunity for a petitioner to
    challenge the basis for the Agency’s decision. Reply at 2, citing IEPA v. PCB, 138 Ill. App. 3d
    550, 551-52 (3rd Dist. 1985). Ayers cites IEPA for the proposition that the Board hearing
    includes consideration of the record before the Agency together with receipt of testimony and
    “other proofs under the full panoply of safeguards normally associated with due process
    hearing.”
    Id
    . Ayers asserts that this includes not only information before the Agency at the time
    of the decision, but also testimony explaining how the Agency record demonstrates that the
    HPCAP should have been approved. Reply at 2, citing Waste Management of Illinois v. IEPA,
    PCB 84-45 (Nov. 26, 1984) and Todd’s Service Station v. IEPA, PCB 03-2 (Jan. 22, 2004).
     
    Board Discussion
     
     
    The following discussion will first clarify the standard of review used by the Board in
    this proceeding. Next, the Board will discuss the Agency rate sheet and applicability to this case.
    Finally, the Board will discuss the technical and financial review performed by the Agency.
     
    Standard of Review
     
     
    Both parties agree and the law is well settled that the denial letter frames the issues on
    appeal. The Board’s review is based on the record before the Agency, and the petitioner bears
    the burden of demonstrating that the application as submitted demonstrates compliance with the
    Act and Board regulations.
    See
    infra 8. However, Ayers does correctly point out that the
    hearing before the Board is the petitioner’s first opportunity to explain how the Agency record
    supports the application. Further, although the Board’s review is limited to the record before the
    Agency, the Board does not review the Agency’s decision using a deferential manifest-weight of
    the evidence standard. IEPA v. PCB, 115 Ill. 2d 65, 70, 503 N.E.2d 343, 345 (1986). Rather the
    Board reviews the entirety of the record to determine that the HPCAP as presented to the Agency
    demonstrates compliance with the Act.
     
    Rate Sheet
     
     
    Ayers main argument is that the Agency rate sheet is an unpromulgated rule that violates
    the APA by proscribing maximum allowable costs for items in a HPCAP. Ayers maintains that
    the court’s decision in Senn Park was based on similar circumstances and is therefore
    precedential. The Agency argues that the rate sheet is an internal document expressly used in
    promotion of consistency in decisions. Ag. Br. at 8. The Agency also argues that the
    circumstances surrounding the rate sheet are not similar to Senn Park and therefore that decision
    does not apply.
     
    The Board will first look to the definition of a rule in the APA, and will apply that
    definition to the facts of this case. The APA defines a rule as:
     
    each agency statement of general applicability that implements, applies, interprets
    or prescribes law or policy, but does not include (i) statements concerning only

     
    16
    the internal management of an agency and not affecting private rights or
    procedures available to persons or entities outside the agency . . . . 5/ILCS 100/1-
    70 (2002)
     
    The testimony of Agency personnel in this case shows that the rate sheet is a statement of
    Agency policy, which limits the amount of charges reimbursable for corrective action at a
    leaking underground storage tank site. The Agency’s personnel indicated that if a rate was
    sought higher than the one listed on the rate sheet, the rate was reduced, unless additional
    information was provided.
    See
    Tr. at 215-17. The testimony of both Ms. Hawbaker and Mr.
    Bauer demonstrate that although the rate sheet is kept “secret” from the public, the rate sheet is a
    statement of general applicability.
    See
    Tr. at 185-6; 225-6. Furthermore, the rate sheet is used to
    affect the claims for reimbursement, by persons outside the Agency, from the leaking
    underground storage tank fund. Thus, the Board finds that, by definition, the rate sheet is a rule
    that the Agency should have promulgated pursuant to the APA.
     
    The Board finds that, since the Agency rate sheet is a rule that was not promulgated and
    is of the type the courts have found invalid, the Board is not bound by the Agency rate sheet and
    the rate sheet has no legal or regulatory effect. Platolene 500, Inc. v. IEPA, PCB 92-9 (May 7,
    1992),
    slip op.
    at 8. However even though the Board agrees with Ayers that the rate sheet is an
    improperly promulgated rule and the rate sheet has no binding effect on the Board, the Board
    will not strike the evidence in the record on the Agency rate sheet. The Board will accept the
    Agency’s testimony regarding the rate sheet and the rate sheet as rebuttal to Ayers’ argument
    that the rates in the HPCAP are reasonable and should be approved.
     
    Technical and Financial
     
    The Agency’s denial letter frames the issue on appeal and the denial letter states that 10
    of the direct push soil borings are in excess of those needed. The denial letter states that because
    BTEX testing will be done on only three of the suggested 13 soil borings, the remaining 10 soil
    borings are excessive since it appears that they would be used to only further classify the soils
    that were previously classified during the site classification activities. R. at 86-87. However, the
    testimony of Mr. Truesdale indicates that during meetings with the Agency, in his understanding
    the Agency had objected only to chemical analysis being performed on all the soil borings, so
    Ayers reduced the number of soil borings that would be chemically tested. Tr. at 104. Mr.
    Truesdale elaborated in his testimony that although only 3 soil borings would be analyzed for
    BTEX, all 13 soil borings were intended to be logged and used “to further evaluate the natural
    migration pathways identified during site classification” both on and off site. Tr. at 49, 50, 101.
     
    Also, the site classification indicated the presence of soils with variable composition and
    thickness, and Mr. Truesdale testified that such variabilities needed to be quantified to further
    evaluate migration pathways on and off site. Tr. at 71-72, R. at 8. In addition, the record
    contains several references, which indicate that the 13 soil and groundwater borings are being
    proposed to establish the extent of contamination in order to develop future groundwater
    monitoring program and evaluate potential remediation strategies.
    See
    R. at 1, 6, and 8. This is
    consistent with the additional soil borings and analysis allowed under Section 732.404(e) for the
    development of a corrective action plan. In contrast, the Agency relies on one statement in the

     
    17
    record for support that 10 of the 13 soil borings are only for further site classification.
    See
    Tr. at
    176-7. After careful review of the record, the Board finds that there is ample evidence that the
    soil type found at the site requires the 13 soil borings on and off site along with the proposed
    physical and chemical analysis to establish the extent of the contamination and aid in developing
    future groundwater monitoring and remediation strategies. Therefore, the Board finds that the
    HPCAP’s provision for 13 direct push soil borings is necessary to meet the minimum
    requirements of the Act and the Board’s regulations.
     
    The Board also finds that the Agency statement in the denial letter that eight direct push
    borings per day can be accomplished is contrary to the record. The record clearly indicates that
    the direct push borings will be used for groundwater and soil monitoring. There is ample
    testimony in the record to establish that the time necessary to do groundwater monitoring makes
    the installation eight direct push borings per day unlikely. Therefore, the Board finds that the
    five days for investigation in the HPCAP is necessary to meet the minimum requirements of the
    Act and the Board regulations.
     
    Because the Board finds that the 13 soil borings are not excessive and five days of
    investigation are necessary, several cost reductions must be restored in the HPCAP. First, the
    investigation costs must be restored to allow for the 10 soil borings eliminated by the Agency to
    proceed. Also, the corresponding reduction in personnel costs must be restored. Equipment
    costs, camera, Peristaltic pump (field purchases) and handling charges must also be restored
    consistent with the reinstatement of 13 soil borings and five days of drilling.
     
    As to the reduction taken based on the hourly rates charged for the personnel at the site,
    Ms. Davis testified that the rates had been previously approved and explained how the rates were
    developed. Tr. at 126-40. The Agency relies on the rate sheet for the reduction and argues that
    the information in Ms. Davis testimony was not before the Agency when the Agency made the
    decision to reduce the rates. Therefore, the Agency would have the Board disregard the
    testimony. As noted above, the Agency’s record is the basis for the Board’s review; however,
    the hearing before the Board is the petitioner’s first opportunity to challenge the Agency’s
    decision and the Agency’s reasoning. In this case, the Agency determined rates were
    unreasonable based on a rate sheet. The Board finds that the explanation of Ms. Davis is
    properly before the Board as are the challenges to the rate sheet. Given the evidence, the Board
    is convinced that the rates requested by Ayers for hourly work are reasonable. Therefore, the
    Board finds that the record supports the requested hourly rate and the Board restores the
    reductions for the hourly rate.
     
    As to the adjustment in analytical costs, miscellaneous retail purchases and UPS sample
    shipping, the Board finds that the record does not support restoration of these costs. Although,
    the Agency reviewer reduced the analytical costs based on the rate sheet, Ayers does not point to
    evidence in the record, nor does Ayers adequately explain why the Agency decision is incorrect.
    Furthermore, the Board finds that the record does not justify as reasonable the UPS shipping and
    miscellaneous retail purchases. Although, Mr. Truesdale offered explanations for the cost in his
    testimony, the HPCAP and budget do not contain justifications. Therefore those costs will not
    be restored.

    CONCLUSION
     
    Ayers owns a site in Beardstown where leaking underground storage tanks were reported
    in 2000. On March 28, 2003 the Agency determined that the budget submitted for the high
    priority corrective action plan was excessive, and Ayers filed this appeal on May 7, 2003.
      
    The
    Board finds that, based on the record in this proceeding, the Agency improperly reduced the
    HPCAP budget by reducing the number of soil borings from 13 to three. Because the Board
    restores the number of soil borings to 13, the HPCAP budget is also restored consistent with that
    number of soil borings.
     
    Also, the Board finds that the Agency used an internal rate sheet to reduce the hourly
    personnel rates for various professional activities at this site. The Board finds that the internal
    rate sheet is an improperly promulgated rule and, therefore, the Board is not required to follow
    the provisions of the rate sheet in this proceeding. In reviewing the record, the Board finds that
    the hourly personnel rates requested by Ayers are reasonable and the HPCAP budget is restored
    accordingly.
     
    Finally, the Board finds that Ayers has failed to demonstrate that some requested
    analytical costs, miscellaneous retail purchases, and UPS sample shipping costs are reasonable,
    so the Board affirms the Agency’s decision reducing the HPCAP budget for those items.
