(1) Rule R307-840, R307-841, and R307-842 establi sh procedures and requirements for the accreditation of training programs for lead-based paint activities and renovations, proced ures and requirements for the certification of individuals a nd firms engaged in lead-based paint activities and renovations, andwork practice standards for performing such activities. These ru les also require that, except as outlined in R307-840-1(2), all lead -based paint activities and renovations, as defined in these rul es, must be performed by certified individuals and firms. (2) R307-840, R307-841, and R307-842 apply to all individuals and firms who are engaged in lead-based paint activ ities and renovations as defined in R307-840-2, except person s who perform these activities within residential dwellings that they o wn, unless the residential dwelling is occupied by a person or per sons other than the owner or the owner's immediate family while the se activities are being performed, or a child residing in the buildin g has been identified as having an elevated blood lead level. (3) R307-840, R307-841, and R307-842 identify lea d-based paint hazards. The standards for lead-based paint hazard s apply to target housing and child-occupied facilities. (4) R307-840, R307-841, and R307-842 do not requi re the owner of the property or properties subject to these rule s to evaluate the property or properties for the presence of lead-bas ed paint hazards or take any action to control these conditions if o ne or more of them

is identified. (5) While R307-840, R307-841, and R307-842 establ ish specific requirements for performing lead-based paint activi ties and renovations should they be undertaken, these rules do not require that the owner or occupant undertake any particular lead-based paint activity or renovation. (6) Individuals or firms wishing to deviate from the certification, notification, work practice, or othe r requirements of R307-840, R307-841, and/or R307-842 may do so on ly after requesting and obtaining written approval from the executive s ecretary.

documentation, which provides that an individual or firm will be conducting activities in or to a residential dwelli ng or child-occupied facility that: (i) Shall result in the permanent elimination of lead-based paint hazards; or (ii) Are designed to permanently eliminate lead-b ased paint hazards and are described in paragraphs (1) and (2) of this definition. (b) Projects resulting in the permanent eliminati on of lead-based paint hazards, conducted by firms or ind ividuals certified in accordance with R307-842-2, unless such projects are covered by paragraph (4) of this definition; (c) Projects resulting in the permanent eliminati on of lead-based paint hazards, conducted by firms or ind ividuals who, through their company name or promotional literatur e, represent, advertise, or hold themselves out to be in the busi ness of performing lead-based paint activities as identified and defin ed by this section, unless such projects are covered by paragraph (4) o f this definition;

or (d) Projects resulting in the permanent eliminati on of lead-based paint hazards that are conducted in resp onse to State of

Utah or local abatement orders. (4) Abatement does not include renovation, remode ling, landscaping or other activities, when such activiti es are not designed to permanently eliminate lead-based paint hazards, but, instead, are designed to repair, restore, or remodel a given str ucture or dwelling, even though these activities may incidentally resul t in a reduction or elimination of lead-based paint hazards.
