(b) Place an impenetrable material on the ground, at the paint removal worksite, to keep any and all spent abrasive, paint, particulate, dust and/or other debris generated by the paint removal operation from being deposited on the ground. If a wet removal system is to be used, procedures must be employed to contain any and all residues generated by the wet abrasive blasting operations. (c) The ground sheeting must be attached to ground by staking, weighing down or any other method to insure that it remains in place during the paint removal operation. (d) If abrasive blasting, machine sanding or machine scraping is to be employed, close all doors and windows on the walls to be blasted or sanded and securely seal them from the outside. Air conditioning units on these and adjacent walls must be turned off and covered. (e) Erect vertical containment shrouds if there is visible movement of abrasive material, paint, dust and/or other debris beyond ground sheeting. (f) If a wet removal procedure is to be used, a system must be in place prior to initiation of 5 the removal which allows liquid waste to be collected from the ground containment and placed into appropriate containers for proper disposal. 24.4.2 Site preparation for exterior paint removal from structures other than buildings must be adequate to prevent spent abrasive material, paint, particulate, dust and/or other debris from being deposited on the ground or in water or travelling offsite. Prior to removing paint from structures other than buildings, the person performing the paint removal work and/or the contractor responsible for the removal operation must submit a plan, that describes the procedure to be employed, to the Division for approval. The paint removal operation must not be initiated until written approval is issued by the Division. 24.5 Requirements for Removal of Lead Paint Using Heat Based Methods 24.5.1 Open flame burning shall not be used to remove paint from exterior surfaces. 24.5.2 Heat guns and/or any other device used for removal of paint from exterior surfaces must be operated such that the temperature of the gun and/or other device does not exceed 1000 oF. 24.6 Requirements for Removal of Lead Paint Using Chemical Based Methods 24.6.1 Flammable paint strippers and paint strippers containing methylene chloride shall not be used to remove paint from exterior surfaces. 24.6.2 Non-flammable paint strippers which do not contain methylene chloride may be used for the removal of exterior paint provided that the manufacturers instructions for use of the paint stripper are followed. 24.7 Requirements for Removal of Lead Paint Using Mechanical Methods 24.7.1 Machine sanding and/or machine scraping shall be allowed only if the unit is controlled by a HEPA vacuum unit which immediately collects any and all spent abrasive, paint, particulate, dust and/or other debris generated by the operations.
