Reevaluation means a visual assessment of painted surfaces and limited dust and soil sampling conducted periodically following lead-based paint hazard reduction where lead-based paint is still present.

24 CFR 35.1355
  (b) Reevaluation. Reevaluation shall be conducted in accordance with this paragraph (b), and the designated party shall conduct interim controls of lead-based paint hazards found in the reevaluation.
  (1) Reevaluation shall be conducted if hazard reduction has been conducted to reduce lead-based paint hazards found in a risk assessment or if standard treatments have been conducted, except that reevaluation is not required if any of the following cases are met:
  (i) An initial risk assessment found no lead-based paint hazards;
  (ii) A lead-based paint inspection found no lead-based paint; or
  (iii) All lead-based paint was abated in accordance with Sec. 35.1325, provided that no failures of encapsulations or enclosures have been found during visual assessments conducted in accordance with
Sec. 35.1355(a)(2) or during other observations by maintenance and repair workers in accordance with Sec. 35.1355(a)(5) since the encapsulations or inclosures were performed.
  (2) Reevaluation shall be conducted to identify:
  (i) Deteriorated paint surfaces with known or suspected lead-based paint;
  (ii) Deteriorated or failed interim controls of lead-based paint hazards or encapsulation or enclosure treatments;
  (iii) Dust-lead hazards; and
  (iv) Soil that is newly bare with lead levels equal to or above the standards in Sec. 35.1320(b)(2).
  (3) Each reevaluation shall be performed by a certified risk assessor.
  (4) Each reevaluation shall be conducted in accordance with the following schedule if a risk assessment or other evaluation has found deteriorated lead-based paint in the residential property, a soil-lead hazard, or a dust-lead hazard on a floor or interior window sill. (Window troughs are not sampled during reevaluation). The first reevaluation shall be conducted no later than two years from completion of hazard reduction. Subsequent reevaluation shall be conducted at intervals of two years, plus or minus 60 days. To be exempt from additional reevaluation, at least two consecutive reevaluations conducted at such two-year intervals must be conducted without finding lead-based paint hazards or a failure of an encapsulation or enclosure. If, however, a reevaluation finds lead-based paint hazards or a failure, at least two more consecutive reevaluations conducted at such two year intervals must be conducted without finding lead-based paint hazards or a failure.
  (5) Each reevaluation shall be performed as follows:
  (i) Dwelling units and common areas shall be selected and reevaluated in accordance with Sec. 35.1320(b).
  (ii) The worksites of previous hazard reduction activities that are similar on the basis of their original lead-based paint hazard and type of treatment shall be grouped. Worksites within such groups shall be selected and reevaluated in accordance with Sec. 35.1320(b).
  (6) Each reevaluation shall include reviewing available information, conducting selected visual assessment, recommending responses to hazard reduction omissions or failures, performing selected evaluation of paint, soil and dust, and recommending response to newly-found lead-based paint hazards.
  (i) Review of available information. The risk assessor shall review any available past evaluation, hazard reduction and clearance reports, and any other available information describing hazard reduction measures, ongoing maintenance activities, and relevant building operations.
  (ii) Visual assessment. The risk assessor shall:
  (a) Visually evaluate all lead-based paint hazard reduction treatments, any known or suspected lead-based paint, any deteriorated paint, and each exterior site, and shall identify any new areas of bare soil;
  (b) Determine acceptable options for controlling the hazard; and
  (c) Await the correction of any hazard reduction omission or failure and the reduction of any lead-based paint hazard before sampling any dust or soil the risk assessor determines may reasonably be associated with such hazard.
  (iii) Reaction to hazard reduction omission or failure. If any hazard reduction control has not been implemented or is failing (e.g., an encapsulant is peeling away from the wall, a paint-stabilized surface is no longer intact, or gravel covering an area of bare soil has worn away), or deteriorated lead-based paint is present, the risk assessor shall:
  (a) Determine acceptable options for controlling the hazard; and
  (b) Await the correction of any hazard reduction omission or failure and the reduction of any lead-based paint hazard before sampling any dust or soil the risk assessor determines may reasonably be associated with such hazard.
  (iv) Selected paint, soil and dust evaluation. (A) The risk assessor shall sample deteriorated paint surfaces identified during the visual assessment and have the samples analyzed, in accordance with 40 CFR 745.227 (b)(3)(4), but only if reliable information about lead content is unavailable.
  (b) The risk assessor shall evaluate new areas of bare soil identified during the visual assessment. Soil samples shall be collected and analyzed in accordance with 40 CFR 745.227(d)(8)-(11), but only if the soil lead levels have not been previously measured.
  (c) The risk assessor shall take selected dust samples and have them analyzed. Dust samples shall be collected and analyzed in accordance with Sec. 35.1320(b). At least two composite samples, one from floors and the other from interior window sills, shall be taken in each dwelling unit and common area selected. Each composite sample shall consist of four individual samples, each collected from a different room or area. If the dwelling unit contains both carpeted and uncarpeted living areas, separate floor samples are required from the carpeted and uncarpeted areas. Equivalent single-surface sampling may be used instead of composite sampling.
  (7) The risk assessor shall provide the designated party with a written report documenting the presence or absence of lead-based paint hazards, the current status of any hazard reduction and standard treatment measures used previously and any newly-conducted evaluation and hazard reduction activities. The report shall include the information in
40 CFR 745.227 (d)(11), and shall:
  (i) Identify any lead-based paint hazards previously detected and discuss the effectiveness of any hazard reduction or standard treatment measures used, and list those for which no measures have been used.
  (ii) Describe any new hazards found and present the owner with acceptable control options and their accompanying reevaluation schedules.
  (iii) Identify when the next reevaluation, if any, must occur, in accordance with the requirements of paragraph (b)(4) of this section.
  (c) Response to the reevaluation.
  (1) Hazard reduction omission or failure found by a reevaluation. The designated party shall respond in accordance with paragraph (b)(6)(iii)(A) of this section to a report by the risk assessor of a hazard reduction control that has not been implemented or is failing, or that deteriorated lead-based paint is present.
  (2) Newly-identified lead-based paint hazard found by a reevaluation. The designated party shall treat each:
  (i) Dust-lead hazard or paint lead hazard by cleaning or hazard reduction measures, which are considered completed when clearance is achieved in accordance with Sec. 35.1340.
  (ii) Soil-lead hazard by hazard reduction measures, which are considered completed when clearance is achieved in accordance with Sec. 35.1340.
