HUD Ch. 11: Interim Control Flashcards
Involves stabilizing any deteriorated paint on the assumption that all deteriorated paint contains lead, thoroughly cleaning all surfaces, and covering all bare soil
Interim control
Should be followed by a risk assessment
Site-specific lead hazard control plan
- Identify hazards
- Feasibility of control measures
- Occupant protection
- Financing
- How and when ongoing monitoring should
When are interim controls appropriate?
- When most surfaces with lead-based paint are intact and structurally sound
- Lead exposure comes primarily from deteriorating paint and excessive lead levels of lead in household dust and/or soil
- If housing unit is slated for demolition or renovation within a few years
Lead hazards must be abated in the course of substantial rehab projects using more than $________ of Federal Funds per dwelling unit
$25,000
per Title X
Unless prohibited, the property owner may elect to proceed with lead hazard control measures without a ______ Assessment or paint inspection.
Risk Assessment
When no evaluation is conducted, the property owner must assume all surfaces have lead-based paint, all floors and dust traps are contaminated, and all bare soil is contaminated.
Documentation required:
- Risk Assessment and/or Inspection Report
- Lead Hazard Control Plan
- Clearance Examination Report
- Reevaluation Reports
- Maintenance & Monitoring Log
- Statement of Lead-Based Paint Compliance
Reevaluations should occur _________, as indicated in the site-specific schedule
annually
For exterior work, collect _______ ________ before work begins
soil samples
Needed for the clearance inspection
Clearance testing should be performed_________
Whenever a job creates dust
A dust lead hazard is defined as:
interior floor: >/= 40 micrograms/ft2
interior horz. surface: >/= 250 micrograms/ft2
exterior horz. surface: >/= 400 micrograms/ft2
(CDPH & HUD & EPA)
Lead contaminated soil is defined as:
Child’s play area: >/= 400 ppm
All other areas: >/= 1000 ppm (CDPH)
>/= 1200 ppm (EPA & HUD)
Definition of lead-based paint:
> /= 1.0 mg/cm2 (XRF)
OR
/= 0.5% by weight (chip sample)
For soil sampling, a child play area includes:
bare soil in areas where children play, including sandboxes.
Non child play areas to take soil samples:
- dripline/foundation area (recommended to always sample here - shown to have higher lead levels)
- vegetable gardens
- bare pathways
- pet sleeping areas
If bare soil areas total less than _____sq. ft., sampling of non-play areas of the yard is not necessary
9 sq. ft.
The top _____inch of soil should be collected
5/8th inch
If paint chips are present in soil they should be ______
included in the sample.
but make no attempt to target areas with visible paint samples
Sub samples should be taken ____to____ft. apart
2 to 6 feet apart
For gardens ____to____ samples should be taken at depths of ____to_____inches to account for previous soil mixing
6 to 12 samples; 3-4 inches
Types of interim controls:
- REPAIRING all rotted or defective substrates that could lead to rapid paint deterioration
- Paint film STABILIZATION (by removing det. & repainting)
- FRICTION & IMPACT SURFACE TREATMENT (floors , sills and troughs so they are smooth and cleanable)
- FRICTION & IMPACT SURFACE TREATMENT such as windows, doors, stair treads, and floors when they are generating lead-based paint chips or excessive levels of leaded dust
- TREATING PROTRUDING accessible surfaces, where there is evidence showing kids are CHEWING on them
- TREATING ALL BARE SOIL containing excessive levels of lead
- DUST REMOVAL and control (cleaning to reduce lead levels
- EDUCATING residents and maintenance workers on how to avoid lead poisoning
- Conducting REEVALUATIONS by certified individuals, ongoing monitoring by owners, and observation by residents
