What’s new in Safe Fill What’s new in Safe Fill Definition?Definition?

Definition is short as a result of:– Due diligence procedures moved to § 287.11(b)– Exceptions transformed into a new section, §287.12

Definition is limited to the following uncontaminated materials: – soil containing stone and rock– dredged material– used asphalt– brick, block, concrete (segregated or mixed) from C/D

activities

3

Safe Fill DefinitionSafe Fill Definition (continued)(continued)

Safe fill materials meet the following:– Not affected by a spill or release– No visible staining, odor or sensory nuisance from chemical

contaminants associated with the material– Meet numeric standards of §287.11(b) --- lower of

residential GV or DC (SHS), based on due diligence– Determination that material is safe fill based on §287.12 – Burden of proof on user to demonstrate material is safe fill– Safe fill not regulated as waste when used as fill

4

Safe Fill Due Diligence and Safe fill Safe Fill Due Diligence and Safe fill Numeric Standards – Numeric Standards – §§287.11287.11

Due diligence requirements now in 287.11(a)– 2 options instead of proposed three options; field screening

allowed

Numeric standards moved from §287.11(a) to §287.11(b)– No change from proposed except following:

PQL added to §287.1(b)(1)(C) to demonstrate compliance with SF numeric standards if std. lower than PQL

5

Safe Fill Due Diligence and Safe fill Safe Fill Due Diligence and Safe fill Numeric Standards – Numeric Standards – §§287.11287.11

No changes to proposed composite and discrete sampling procedures in 287.11(now subsections c, d & e) except added subsection (f) as follows:– Statistical analysis requirements added to §287.11(f)

95% UCL of the arithmetic mean to demonstrate material meets SF numeric standards

Overall, draft final regulations will allow for field and laboratory screening of material including composite, discrete and statistical sampling and analyses

– As fill for residential purposes except blending required with clean soil/dredge and blend must meet safe fill numeric standards

8

New New §287.12(a)(1)§287.12(a)(1) (continued)(continued)

Determination requires:– Appropriate level of due diligence to

demonstrate material not subject to a spill/release and below nonresidential numeric standards

– Maintain documentation in support of determination

– Submit Notice of Determination to Department

9

New New §287.12(a)(2)§287.12(a)(2) (continued)(continued)

§287.12(a)(2): Material affected by a spill or release:– Applies to soil, dredged material or historic fill only– Visible staining acceptable but no odor or nuisance– Num. standards may be above SF but < nonresidential SHS

Use limited to:– Right-of-way– For historic fill, can be moved offsite in amounts < 500

cy/excavation location; used as fill or as construction material

– Within a property

10

New New §287.12(a)(2) §287.12(a)(2) (continued)(continued)

Determination requires following: – Must conduct sampling /analysis to demonstrate

material is below nonresidential num. standards (cap)– Maintain documentation to support determination– Submit Notice of Determination to Department– Submit proof of recorded, amended deed to Department

that includes following: Deed includes exact location of the fill placed on the property Deed to be part of all future conveyances or transfers of

subject property

11

New New §287.12(c)(7) §287.12(c)(7) (continued)(continued)

Deed notice not required for:– Material is not affected by a spill or release, is

above safe fill but below nonresidential standards and no visible staining, odor, nuisance

– Material is affected by a spill or release, is above safe fill numeric standards but at or below background level at the property

12

New §287.13. Relationship of Safe New §287.13. Relationship of Safe Fill to surface Waters Fill to surface Waters

For placement of safe fill (meets definition and SF numeric standards) into or along surface waters, following required:– Approval under Chapter 105– May not produce leachate in excess of residential GWMSC

for used aquifer and TDS<2500 mg/L by SPLP– Comply with water quality standards in Chapters 93 & 16

If safe fill determination based on §287.12, cannot be placed into waters of the Commonwealth

13

New §287.13New §287.13(continued)(continued)

For placement into waters in active/abandoned mine or abandoned quarry as reclamation:– Approved sampling/analysis plan– Comply with water quality standards in Chs.93 and 16– 10% of safe fill numeric standards– For metals, in lieu of 10%, SPLP analysis to show

material will not produce leachate in excess of residential GWMSC for used aquifer/TDS<2500 mg/L. Applies only if GW monitoring is conducted where material is placed
