The  Environmental  Protec1on  Agency  (EPA)  is  upda1ng  the  rules  for  using  chemicals,  including  dispersants,  for  responding  to  oil  spills  in  the  United  States.    

SUBPART  J  –  Regula1ng  Dispersants  

WAF:    Water  Accommodated  Frac.on  

2  

What  are  dispersants  and  how  are  they  supposed  to  work?  Dispersants  are  chemicals  applied  to  spilled  oil  to  try  to  break  down  the  oil  into  small  par1cles  with  the  hope  that  these            par1cles  disperse  into  the  water  column  rather  than      

         remain  floa1ng  on  the  surface                  in  a  slick.

Why  update  the  rule  that  deals  with  dispersants?    

 �    It  has  been  21  years  since  the  rule  was  first  introduced.    

   �    To  address  concerns  from  the  2010  BP  Deepwater  Horizon        oil  spill  where  an  unprecedented  amount  of                          dispersants  was  used    (over  1.8  million  gallons  of  

           dispersants  were  applied)    

   �    Several  environmental  groups  sued  the  EPA  to  update  the        rule  to  address  new  informa1on    

 

What  is  Subpart  J  ??  �    EPA’s  rule  or  guidance  regarding  the  use  of  dispersants  and  other  

 chemicals  when  responding  to  oil  spills      �    Called  Subpart  J  because  the  rule  is  in  that  sec.on  of  the  na.onal  

 con.ngency  plan  (NCP)    �  Includes  a  “catalog”  of  dispersants  that  are  approved  by  the  EPA    �  Spells  out  where  dispersants  can  be  used,  and  how  much  may  be  used    

Public  Review:    This  spring,  EPA  sought  public  input  on  the  sec1on  of  the  NCP  that  governs  use  of  dispersants  and  other  chemical  and  biological  agents  when  responding  to  oil  spills.    More  opportuni.es  to  comment  are  likely!      

PWSRCAC  Review  and  Commen1ng  Process  �  The  council  project  team  began  review  at  the  start  of  the  90  day    

 public  comment  period    �  The  team  started  out  with  staff  and  volunteers,  added  contractors      and  reached  out  to  regulators  (current  and  re1red)  and  others  

 �  The  team  developed  several  draWs,    

 refining  as  they  went    �  Final  product  approved  by  the  Execu1ve    

 CommiZee  prior  to  the  comment      deadline  

 �  This  allowed  comments  to  be    

 shared  with  Member  organiza1ons,      stakeholders,  and  other  interested      par1es.  

PWSRCAC  Review  –  Some  Key  Issues  �  Cau1ous  approach  to  use  of  chemicals  �    Emphasis  on  science-­‐based  decision-­‐making    �  Toxicity  and  chronic  effects    �    Emphasis  on  authorizing  dispersants  before  a  spill  happens  

�    Reliance  on  responsible  party  and  manufacturer  science
