Chemical Release Quantity - Environment Aspects & Impacts

Hi,

I have identified aspect as "Chemcial release as emission to air or water". The quanity relase is scaled & scored up as very low/low/high...... in quantiy table. Release Quanity is one of the multipling factor in evalauting this aspect.

As per the ISO-14001 standard assessment methology is in placed and based on experience significant or insignificance scores are set .

I would like to know the following while carrying out assesment :

1. Is it correct way to follow the release quantity (in kg/hr) & refering it to predefined Quanity table ( prepared based on annual cons. ) and then go for evalaution. The quanity of chemcial is based on the annual consumption of - used in process ( sometimes released) .

Or

2. Refer the release quanity table based on EPA Cercla Repotable Quanity (RQ) defined for all process hazardous chemcials which i think takes of environment impact ( eco-toxicity issues .....). Using the EPA Cercla RQ table for evalauting the aspects.

The RQ quanitites defined are for just reporting to authorities but can it be used as basis for environment aspect/impact assesment on quanity factor.

What I think, the ISO-14001 standard gives only guidlines & methodology but the basis for deriving the release quanitites and adopting it should based on Industry standards or from established regulatory body.

Anybody can guide & comment on this issue on which is the betterway to adopt the release quanity either on:
1. Derived based on annual cons. OR
2. can be taken from EPA Cercla RQ's

Hi,

How to evaluate aspects for significance is left to the organization establishing/maintaining an EMS.

If your interest is indeed "continual improvement", the criteria you mention for assessing significance are only certain milestones in your journey towards excellence in environmental performance. Ideally your goal has to be to eliminate emissions and discharges in your operations; but in practice people follow EVABAT - Economically Viable and Best Available Technology (i.e. lowest possible emissions and discharges using the principle of EVABAT). Would you like to use emissions and discharges achieved by EVABAT as criteria for assessing Significance ? In my opinion, EVABAT takes care of compliance with legislation, as given.

With best regards,

Ramakrishnan
