THIS DRAWING SET IS ISSUED IN COORDINATION WITH THE MATERIAL MANAGEMENT PLAN (MMP) FOR EXCAVATION OF SOME CONTAMINATED SOILS FROM EXPOSURE AREA B (HALEY & ALDRICH, INC., NOVEMBER 5, 2024). THE CONTRACTOR PERFORMING THE CONTAMINATED SOIL REMOVAL ACTION AND RELATED WORK SHALL ADHERE TO THE REQUIREMENTS OF BOTH THE DRAWING SET AND THE MMP.

EXCAVATION NOTES

1. ENSURE ALL PERIMETER E&S CONTROLS ARE IN PLACE PRIOR TO BEGINNING EXCAVATION

WORK.

2. ALL DEMOLITION DEBRIS AND SOIL EXCAVATION MATERIALS SHALL BE DISPOSED OF IN AN

OWNER-APPROVED, OFFSITE LICENSED LANDFILL FACILITY.

3. MASS CONCRETE REMOVAL IS NOT INCLUDED IN THIS SCOPE.

4. AT THE END OF EACH WORKDAY, THE LOAD-OUT AREA SHALL BE CLEANED OF SPILLED

MATERIAL TO PREVENT MATERIAL TRANSPORT FROM RAINFALL OR VEHICLE TRACKOUT.

5. PROTECT THE WORK FROM SURFACE WATER INFLOW OR OTHER MATERIALS UNTIL

BACKFILL IS COMPLETE AND STABILIZED.

6. DRAWING C-102 OF THIS DRAWING SET INDICATES THE ANTICIPATED AREA OF SOILS

REMOVAL IN EXPOSURE AREA B. THE AREA WAS SELECTED TO REDUCE THE VOLUME OF

SOILS CONTAMINATED WITH THE HIGHEST CONCENTRATIONS OF LEAD AND PCBs AS MUCH

AS PRACTICAL. BASED ON THE RCRA “RULE OF 20” PROTOCOL, SOILS WITH TOTAL LEAD

CONCENTRATIONS GREATER THAN 100 MG/KG WERE CONSIDERED TO BE RCRA

CHARACTERISTICALLY HAZARDOUS WASTE. THE RESULTS OF THE RULE OF 20

DETERMINATION SHALL BE CONFIRMED WITH SPECIFIC WASTE PROFILING VIA TCLP

ANALYSES FOR LEAD. BASED ON THE PROFILING RESULTS, THE LIMITS OF EXCAVATION

MAY BE ADJUSTED AND MAY INCLUDE SOME AREAS OF NON-HAZARDOUS WASTES.

7. THE CONTRACTOR PERFORMING SOILS REMOVAL SHALL BE RESPONSIBLE FOR PROPERLY

PROFILING THE CONTAMINATED SOILS FOR PROPER OFF-SITE DISPOSAL. EXPOSURE AREA

B CONTAMINATED SOILS ARE SUBJECT TO THE MMP AND WILL BE SAMPLED AND

CHARACTERIZED USING PROTOCOLS AND ANALYTICAL METHODS APPROPRIATE FOR THE

MATERIALS FOR PROFILING AND DISPOSAL. THE NUMBER OF SAMPLES NECESSARY TO

PROFILE THE WASTE WILL BE DETERMINED BY THE DISPOSAL FACILITY’S OPERATING

PERMIT AND/OR VDEQ REGULATIONS/GUIDANCE. ANALYTICAL RESULTS WILL BE USED TO

OPTIMIZE/MAXIMIZE THE VOLUME OF SOIL THAT CAN BE REMOVED AND TO DETERMINE HOW

THE MATERIALS MUST BE MANAGED.

8. IN ADDITION, SUFFICIENT SOIL SAMPLES (MINIMUM 12) SHALL BE COLLECTED FOR LEAD

CHARACTERIZATION VIA TCLP ANALYSIS TO DEMARCATE BETWEEN NON-HAZARDOUS

WASTE SOILS AND RCRA CHARACTERISTICALLY HAZARDOUS SOILS. THE CITY SHALL USE

THE RESULTS OF THE LEAD TCLP ANALYSES TO OPTIMIZE THE LIMITS OF EXCAVATION TO

MAXIMIZE CONTAMINATED SOIL REMOVAL UNDER ITS AVAILABLE BUDGETING. THIS MAY

RESULT IN MORE OR LESS SOILS BE EXCAVATED AND MANAGED AS RCRA

CHARACTERISTICALLY HAZARDOUS WASTE AND SOME SOILS BEING EXCAVATED AND

MANAGED AS NON-HAZARDOUS WASTE.

EROSION AND SEDIMENT CONTROL NARRATIVE

PROJECT DESCRIPTION

THIS PROJECT IS BEING UNDERTAKEN TO REMOVE CONTAMINATED SOILS

FROM UNDERNEATH THE SITE SOILS OF THE FORMER RADFORD FOUNDRY

BUILDING. THE AFFECTED AREA WILL HAVE A PORTION OF THE SOIL

EXCAVATED, REMOVED, AND DISPOSED OF IN A LICENSED LANDFILL FACILITY.

THE SOIL WILL BE EXCAVATED TO A DEPTH OF ONE FOOT IN THE INDICATED

AREA. THE EXCAVATED AREA WILL THEN BE BACKFILLED WITH CLEAN SOIL

AND SEEDED. APPROXIMATELY 0.77 ACRES OF LAND DISTURBANCE IS

PROPOSED FOR THIS ACTIVITY.

EXISTING SITE CONDITIONS

THE SITE IS A FLAT CONCRETE FOUNDATION AND SURROUNDING AREAS OF

THE FORMER FOUNDRY BUILDING. MOST OF THE SITE BUILDINGS AND

INFRASTRUCTURE HAVE BEEN REMOVED. SMALL AMOUNTS OF VEGETATION

HAVE BEGUN TO GROW IN THE FOUNDATION AREAS.

ADJACENT AREAS

NORTH OF THE EXCAVATION AREA ARE OTHER PREVIOUSLY-DEMOLISHED

FOUNDRY WORKS BUILDING FOUNDATIONS THAT ARE BEGINNING TO REGROW

VEGETATION.

EAST OF THE EXCAVATION AREA IS THE NEW RIVER, APPROXIMATELY 900 FEET

TO THE EAST AND APPROXIMATELY 50 FEET LOWER IN EXCAVATION.

SOUTH OF THE EXCAVATION AREA ARE OTHER PREVIOUSLY-DEMOLISHED

FOUNDRY WORKS BUILDING FOUNDATIONS THAT ARE BEGINNING TO REGROW

VEGETATION.

WEST OF THE EXCAVATION AREA ARE A PAIR OF RAILROAD TRACKS AND

SMALL COMMERCIAL BUILDINGS THAT ARE SEPARATED FROM THE SITE BY A

SMALL WOODED AREA.

OFF-SITE AREAS

THERE ARE NO OFFSITE AREAS PROPOSED FOR THIS WORK.

SOILS

SITE SOILS IN THE FOUNDRY AREA CLASSIFY AS “URBAN LAND”, MEANING THE

SOIL IS HIGHLY MIXED AND POSSIBLY CONSISTS OF IMPORTED FILLS. THE

RADFORD FOUNDRY SITE HAS BEEN IN OPERATION FOR OVER 100 YEARS.

CRITICAL AREAS

ADJACENT TO THE EXCAVATION AREA TO THE WEST IS SLOPING LAND

TOWARDS THE NEW RIVER. PRECAUTIONS SHALL BE TAKEN TO PREVENT THE

LOSS OF SEDIMENTS OR DEBRIS DOWN THE SLOPE AS WELL AS TO PREVENT

UNFILTERED RUNOFF FROM MAKING ITS WAY DOWN THE SLOPE.

EROSION AND SEDIMENT CONTROL MEASURES

INITIAL SITE CONTROLS: PRIOR TO SITE EXCAVATION, SILT FENCE (STD &

SPEC 3.05), A CONSTRUCTION ENTRANCE (STD & SPEC 3.02), AND FILTER

SOCKS ARE TO BE INSTALLED AS SHOWN ON THE E&S CONTROL PLAN - PHASE

1 (DRAWING C-100).

SITE EXCAVATION: ONCE THE PHASE 1 ITEMS ARE ESTABLISHED, SITE

EXCAVATION CAN BEGIN WITH THE SOIL EXCAVATION. THE MATERIAL

EXCAVATED WILL BE LOADED DIRECTLY INTO TRUCKS ON ADJACENT

CONCRETE AREAS. SPILLED MATERIAL WILL BE CLEANED DAILY BEFORE THE

END OF THE WORK DAY.

PERMANENT STABILIZATION

AFTER MATERIAL REMOVAL, CLEAN BACKFILL SOILS WILL BE BROUGHT IN AND

PLACED. THE SOILS WILL BE LIGHTLY COMPACTED TO A RELATIVELY FLAT

SURFACE TO MATCH THE SURROUNDING AREAS. PERMANENT SEEDING WILL

BE APPLIED.

STORMWATER RUNOFF CONSIDERATIONS AND

CALCULATIONS

IN THE EXISTING CONDITION, STORMWATER RUNOFF HAS NO PARTICULAR

DEFINED PATH DUE TO THE FLAT NATURE OF THE FORMER BUILDING SLAB.

RUNOFF IN THE EXISTING CONDITION IS RELATIVELY HIGH DUE TO THE

IMPERVIOUS NATURE OF THE CONCRETE AND COMPACTED SOILS.

IN THE POST-CONSTRUCTION CONDITION, THE SITE GRADING WILL CLOSELY

MATCH THE PRE-EXISTING CONDITION. STORMWATER RUNOFF SHOULD BE

LOWER DUE TO THE ESTABLISHMENT OF VEGETATION AND A RESULTING

LOWER RUNOFF COEFFICIENT.

SEQUENCE OF CONSTRUCTION
