Vinyl	Institute	Suggested	Checklist	for	Review	of	Final	PVC	MACT	Rule

The	following	documents	are	referenced	and	pages	annotated	for	each	

point	to	provide	context	and	support	for	the	recommendation:

(Doc.	1)	Comments	of	the	Vinyl	Institute,	Inc.	PVC	MACT	Working	Group,	08-02-11,	

Docket	ID	No.	EPA-HQ-OAR-2002-0037-0146;

(Doc.	2)	Corrected	VI	PVC	MACT	Working	Group	Comments,	09-12-11;

(Doc.	3)	VI	PVC	MACT	Supplemental	Comments,	09-12-11;

(Doc.	4)	PolyOne	PVC	MACT	USEPA	Henry	IL	Suspension	Blending	Data	Submission,	09-30-11;	

and

(Doc.	5)	VI	PVC	MACT	Direct	Economic	Impact	Estimate	for	EPA,	10-27-11.

Two	overarching	considerations	for	OMB	as	it	reviews	EPA’s	draft	final	rule:

 Do	not	allow	foreign	sourced	resins	to	supplant	U.S.	producers	that	

already	meet most	rigorous	emissions	limits	in	the	world;	(Doc.	5)	p.	3

 Do	not	burden	PVC	resin	consumers	with	the	expense	to	compensate	

for	poorer	quality	resins	produced	to	meet	EPA	limits;	(Doc.	5)	p.	2,	5,	

7-8

Specific	recommendations	that	EPA	must	consider	in	drafting	the	final	rule:

 Ensure	that	MACT	floors	are	properly	calculated;	(Doc.	2)	p.	4-6

 Subcategorize	resins	on	basis	first	of	raw	material	monomer,	then	on	

basis	of	process,	and	equipment;	(Doc.	2)	p.	13-19,	(Doc.	3)	p.	6-10,

(Doc.	4)

 Use	normalized,	updated,	and	supplemental	datasets	provided	by	

industry;	(Doc.	1)	Attachment	7A,	7B,	7C,	7D,	12,	(Doc.	2)	Corrections	

to	Attachment	7C,	(Doc.	4)	Supplements	to	Attachment	7C

 Apply	99.9	percentile	for	vinyl	chloride	resin	limit	using	VI	4-year	

database	determined	using	M107	test	method	for	each	subcategory;	

(Doc.	2)	p.	28

 Assure	daily	compliance	for	RVCM	in	resin	determined	using	M107	is	

the	same	test	method	used	for	data	to	calculate	resin	floor	limits;	

(Doc.	2)	p.	20-24

 Calculate	rolling	monthly	total	HAPs	limits	using	99%	UPL	with	30-day	

statistical	factor	of	m=12	applied	to	best	performers	by	individual	HAP	

added	together	for	total	monthly	HAPs;	(Doc.	2)	p.	27,	29-35

 Calculate	initial	11	month	compliance	for	monthly	total	HAPs	limits	

using	a	statistical	factor	of	m=1;	(Doc.	2)	p.	39-40

 Recalculate	new	source	limits	based	on	best	performers	by	resin	grade	

to	reflect	the	over	one	hundred	grades	now	made	and	allow	for	

variability	and	flexibility;	(Doc.	2)	p.	100-102

 Do	not	rely	on	increasing	steam	to	resin	stripper	for	reducing	HAPs;	

(Doc.	2)	p.	12

 Emission	limits	for	process	vents	must	be	revised;	calculate	process	

vents	limits	using	PVC-only	control	device	test	data	for	four	target	

HAPs;	(Doc.	1)	Attachment	12,	(Doc.	2)	p.	45-47

 Calculate	separate	emission	limits	for	process	vents	utilizing	absorberstripper	recovery	devices;	(Doc.	2)	p.	48-53

 Like	the	recent	Boiler	MACT,	dioxin	controls	should	be	based	on	work	

practices	and	not	the	unrealistic	emission	limit	in	the	proposed	rule;	

(Doc.	2)	p.	56-59

 Do	not	rely	on	injecting	activated	carbon	in	PVC	waste	gas	control	

devices	for	reducing	HAPs;	(Doc.	1)	Attachment	13,	(Doc.	2)	p.	59	- 60

 Determine	wastewater	limits	using	corrected	database;	(Doc.	1)	

Attachment	7D,	(Doc.	2)	p.	67-69

 Wastewater	limitations	are	incorrect,	needlessly	complex,	and	should	

distinguish	between	in-process	and	maintenance	wastewater;	(Doc.	2)	

p.	69-80

 Requirements	governing	closed	vent	systems	must	be	revised;	(Doc.	2)	

p.	64-67

 Accept	affirmative	defense	for	emergency	release	from	pressure	

safety	devices	instead	of	automatic	violation;	(Doc.	2)	p.	95-98

 The	final	PVC	MACT	should	address	regulatory	overlaps;	(Doc.	2)	p.	

102-104
