INDUSTRIAL ORGANIC COMPOUNDS

????? ??????
All VOC EPA 524.2 Method Exceptions,
non-VOC Benzo(a)pyrene EPA 525.2 Formaldehyde
EPA 556
We have to change the title of the
Table!!! Probably , like Bracha suggested
industrial organic compounds IOC ???

RULES OF REGULATION Iintroduction of new
pollutants

• If the compound is likely to be found in Israel
  it will be included even if only one regulating
  agency included it.
• Small chlorinated solvents should be in even if
  they are regulated by only one of three major
  regulating agencies.
• If there is no data on the abundance of a
  candidate primary pollutant we shall either
  regulate it or propose a concentrate effort to
  establish more data on its abundance (ICR).
• If two out of three agencies have regulations we
  have to include the compound in the Israeli
  Regulations.

RULES OF REGULATION IIvalues of pollutants MCL

• We shall refrain from setting an extreme MCL,
• more extreme than all three regulating agencies.
  
• We shall adopt the values proposed by our
  toxicologist (Professor Winston) in case of
  differences in the MCLs proposed by the major
  regulating agencies.
• We shall refrain as much as possible from
  elevation of an Israeli MCL and do so only
  following a change of the MCL by one or more of
  the major regulating agencies.
• We shall omit MCLs without toxicological/technolog
  ical foundation

5
IOCs which are regulated in Israel and remain
unchanged (mM ppb)
) Chloroforms MCL will be determined by DBPs
subcommittee but will appear in the Industrial
OC list as well

REGULATED IN ISRAEL. (ppb) I

C
A adopting Garys proposal (he suggested 0.2
for vinyl chloride) but this would be too
complicated from analytical point of view, we
accept the 0.5 ppb. Monitoring of VCM will be
conducted in vulnerable areas only as
determined by the Health authority. B never
adopt an extreme MCL the committee recommends a
list of other PAH to an ICR. C -
1,2-dichloroethylenes will be analyzed
individually, as in the whole world, and not
combined as it is now (in Israel only!)

MTBE has been proposed as an indicator for
gasoline contamination, odor threshold 20ppb,
taste 40ppb D according rule 3

Examples of Drinking Water Wells with Combined
pollution
Recommendation The well with com- bined
pollution can be in use, if the the total
percentage of pollutants is less than 150 !!

ADDITIONAL REMARKS I
1. Diethylhexylphthalate has to appear in the
main non-pesticides Table as for industrial
pollutant ( like elsewhere in world).

• 2. EDB and 1,2-Dichloropropane have to appear in
  two Tables as pesticides and as industrial
  organic chemicals.
• (EDB- fuel additive, Dichloroprane solvent)
• It is important for local authorities!!!

14
ADDITIONAL REMARKS II.

• Vinyl chloride appears in the list, but has to be
  analyzed only in vulnerable industrial areas
  according to instructions issued by the health
  authority e.g., Eng. Sh. Goldberger).
• PCBs total concentration of the sum of PCBs
  0.5ppb, it covers Cl5 Cl10 compounds,
• standard Arochlor -1260 can be useful for
  this purpose.
