October 29, 1991 Planning Department County of Frederick 9 North Loudoun Street Winchester, VA 22601 RE: Bulk fuel storage facility - Unimin Corporation, Gore, VA Gentlemen: Please find enM1c;l sed a plant site plan and foundation plan and details for the above referenced project. At this time we are requesting permitting for construction of the containment area only. Additional drawings related to mechanical and elect- rical will follow for the permit process at a later date. Unimin Corporation is under a federal time restraint to have their existing underground storage tanks removed by the end of 1991, therefore we wish to sequence the required local permits to allow for uninterupted plant operations and to meet this deadline. Sizing for the containment arE-a is based on the following criteria: Maximum capacity of largest tank 12'-0" dia. X 36'-6" tall 846.03 gallons per lineal foot in height. 30,880 gallons Minimum capacity of containment area at 110% of largest tank capacity. 33;'968 gallons Averaged containment capacity as drawn including allowances for slopes. 35,968 gallons Add for capacity of sump area 202 gallons Deduct for,above slab tank pads 850 gallons Total usable volume of containment 35,320 gallons Containment capacity as related back to capacity of largest tank within the containment area 1.144% Page 1. continued from page 1 D. K. Erectors & Maintenance, Inc. October 29, 1991 Set -backs for the tanks and containment are based on the following sections and tables from the August 17, 1991 version of the ANSI/NFPA 30 Flammable and Combustible Liquids Code. Set -backs from a Property Lines, Nearest Side of Any Public Way or from Nearest Important Building on the Same Property referenced on Table 2-1 Stable Liquids [Operating Pressure 2.5 psig (17.2 kPa) or Less] under Horizontal and Vertical with Emergency Relief Venting to Limit Pressures to 2.5 psig tank type: Property Lines - 2 times Table 2-6 capacity 30,001 to 50,000 gallons 30 feet X 2 60 foot set -back Any Public Way or Nearest Important Building on the Same Property will be Table 2-6 30,001 to 50,000 gallons 10 foot set -back Set -back from the existing LP tank is based on Section 2-3.2.6 of the same code 20 foot set -back Should you have any question or comment please, feel free to call me.

When tanks are not designed in accordance with the American Petroleum Institute, American Society'of Mechanical Engineers, or the Underwriters Laboratories Inc. Standards, or if corro- sion is anticipated beyond that provided for in the design formulas used, additional metal thickness or suitable pro- tective coatings or linings shall be provided to compensate for the corrosion loss expected during the design life of the tank. 2-3 Installation of Outside Aboveground Tanks. 2-3.1 Location with Respect to Property Lines, Public Ways, and Important Buildings on the Same Property. 2-3.1.1 Every aboveground tank for the storage of' Class I, Class II, or Class IIIA liquids (except as provided in 2-3.1.2), and those liquids with boil -over characteristics and unstable liquids, operating at pressures not in excess of 2.5 psig (17.2 kPa) and designed with a weak roof -to -shell seam (see 2-3.5.3), or equipped with emergency venting devices that will not permit pressures to exceed 2.5 psig (17.2 kPa), shall be located in accordance with Table 2-1. Where tank spacing is contingent on a weak roof -to -shell seam design, the user shall present evidence certifying such construction to the authority having jurisdiction, upon request. (a) For the purpose of Section 2-3, a floating roof tank is defined as one that incorporates either: 30-13 I. A pontoon or double -deck metal floating roof in an open -top tank in accordance with API Standard 650, or 2. A fixed metal roof with ventilation at the top and roof eaves in accordance with API Standard 650 and con- taining a metal floating roof or cover meeting any one of the following requirements: a. A pontoon or double -deck metal floating roof meeting the requirements of API Standard 650. b, A metal floating cover supported by liquidtight metal floating devices that provide sufficient buoyancy to prevent the liquid surface from being exposed when half'of the flotation is lost. (b) An internal metal floating pan, roof, or cover that does not meet the requirements of (a) 2., or one that uses plastic foam (except for seals) for flotation, even if encapsu- lated in metal or fiberglass, shall he considered a fixed roof tank. 2-3.1.2 Vertical tanks having a weak roof -to -shell seam (see 2-3.5.3) and storing Class IIIA liquids may be located at one-half the distances specified in Table 2-1, provided the tanks are not within a diked area or drainage path for a tank storing a Class I or Class II liquid. 2-3.1.3 Every aboveground tank for the storage of (:lass 11 Class 11, or Class IIIA liquids, except those liquids with boil -over characteristics and unstable liquids, operating at pressures exceeding 2.5 psig (17.2 kPa) or equipped with emergency venting that will permit pressures to exceed 2.5 psig (17.2 kPa), shall be located in accordance with Table 2-2.

When flammable or combusti- ble liquid storage tanks are within a diked area, the LP -Gas containers shall be outside the diked area and at least 10 ft (3 m) away from the centerline of the wall of the diked area. The foregoing provisions shall not apply when LP - Gas containers of 125 gal (475 L) or less capacity are installed adjacent to fuel oil supply tanks of 660 gal (2498 L) or less capacity. No horizontal separation is required between aboveground LP -Gas containers and underground flammable and combustible liquid tanks installed in accordance with Section 2-4. 2.3.3 Control of Spillage from Aboveground Tanks. 2-3.3.1 Facilities shall be provided so that any accidental discharge of any Class I, II, or IIIA liquids will be pre- vented from endangering important facilities, and adjoin- ing property, or reaching waterways, as provided for in 2-3.3.2 or 2-3.3.3. Tanks storing Class IIIB liquids do not require special drainage or diking provisions for fire pro- tection purposes. 2.3.3.2 Remote Impounding. Where protection of adjoining property or waterways is by means of drainage to a remote impounding area, so that impounded liquid will not be held against tanks, such systems shall comply with the following: (a) A slope of not less than I percent away from the tank shall be provided for at least 50 ft (15 m) toward the impounding area. (b) The impounding area shall have a capacity not less than that of the largest tank that can drain into it. (c) The route of the drainage system shall be so located that, if the liquids in the drainage system are ignited, the fire will not seriously expose tanks or adjoining property. (d) The confines of the impounding area shall be located so that, when filled to capacity, the liquid level will not be closer than 50 ft (15 m) from any property line that is or can be built upon, or from any tank. 1990 Edition Z 9 on 6. 05.16'59* R - 1610.54' A - 148.50' C ■ 148.45 CB - N 16'46'55" E C2 � - 05.16'59' R ■ 1640.54' A - 151.27' C ■ 151.22' CB ■ S 16.46'55' W C3 !� ■ 35.33'II' R - 522.01' A - 323.92' C - 318.75' CB - N 05'57'34' E 1 / i/10 -09-36 E APPROXIMATE LOCATION X 23_2�_-- — • _ — /i OF DISCHARGE60 °S \ I C I � i SB OSU I 060 / \ x X '06 , x i�� e'er X j.z 10.004 AC i 6 - EXISTING PROCESS AND STORMWATER LAGOON y (no discharge) 87 of ��`.• •;. � ;4%, �P� °4.9 / �• / X / / � / / \ .6 X'0 4 , // /�• / / x / �^� / / X c l / l ' J l I / \ \ x '>o,) X /�>0 N � \ 'EXISTING / 1; P OPOSED ,, \ (�\ / \ �� / / /• // / SAND EXISTING POST x /� __ _ / \ \ // \ \ f / / j // "09 , ,�,' / AERATION"-- `' \ // j/% 7 / FILTER CHLORINE BASIN / �/' /� / x CONTACT I x I j ° BASIN PROPOSED / / / -0 / EXISTING TABLET / x �1J S 4 C2 PUMP DECHLORINATION / / C STATION "� O \ \\ \ CATION 5.24 ACRES 'o F ` C1 EXISTING PROPOSED XI �!0 / ( / / / oo 71 'o� \ AERATION ^ M TABLET 41 BASIN / CHLORINATION ),j LOCATION X l /' X w n9 / /i I / X OFFICE X EXISTING / / X >l BUILDING Z ` 6 CHLORINATION \ \ !
