(collectively, &#8220;Topic 326&#8221;). Topic 326 introduces an approach, based on expected losses, to estimate credit losses on certain
types of financial instruments and modifies the impairment model for available-for-sale debt securities. The new approach to estimating
credit losses (referred to as the current expected credit losses model) applies to most financial assets measured at amortized cost and
certain other instruments, including trade and other receivables and loans. Entities are required to apply the standard&#8217;s provisions
as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted.

years. These ASUs are effective January 1, 2023 for the Company as a smaller reporting company (&#8220;SRC&#8221;). Under new guidance
issued by the Commission in March 2020, the Company will continue to qualify as a smaller reporting company but will also be an accelerated
filer for all filings with the Commission after January 1, 2022. The Company is currently evaluating the impact of these ASU on its consolidated
financial statements.</span></p>

we operate while assuring the continuity of our business operations, particularly in light of emerging new variants of the virus. Similar
to most of the U.S., we have relaxed COVID-19 precautions associated with operations since more people have become vaccinated, including
our employees. However, our Treatment Segment continues to see unexpected delays in waste shipments from certain customers due to impacts
of COVID-19. We expect to see returns in waste receipts from these customers starting in the second half of 2021. Within our
Services Segment, we continue to experience delays in procurement actions and contract awards resulting primarily from the impact of
COVID-19 but have recently begun to receive new contract awards. Within our Treatment and Services Segments, we have an unprecedented
number of bids currently submitted and awaiting awards. We expect procurement actions and contract awards to continue throughout the
second half of 2021.</span></p>

the situations surrounding COVID-19 continues to remain fluid, the full impact and extent of the pandemic on our financial results and
liquidity cannot be estimated with any degree of certainty. We continue to closely monitor the impact of the COVID-19 pandemic on all
aspects of our business, including our customers&#8217; payment performance. However, since a significant portion of our revenues is
derived from government related contracts, we do not expect our accounts receivable collections to be materially impacted due to COVID-19.</span></p>

business operations during the next twelve months. At June 30, 2021, our borrowing availability under our revolving credit facility was
approximately $9,550,000 which was based on a percentage of eligible receivables and subject to certain reserves. We continue to assess
the need in reducing operating costs during this volatile time, which may include curtailing capital expenditures, eliminating non-essential
expenditures and implementing a hiring freeze as needed. Based on our current projection, we believe that we will be able to meet our
current covenant requirements under our loan agreement for the next twelve months, however, such may not be the case due to, among other
things, the uncertainty of COVID on our operations and/or delays in procurement actions, contract awards, or waste shipments.</span></p>

three months ended June 30, 2021 from $22,047,000 for the corresponding period of 2020 due primarily from the impact of COVID-19. The
revenue decrease was primarily within our Services Segment where revenue decreased by approximately $5,768,000 or 40.6% to $8,439,000
for the three months ended June 30, 2021 from $14,207,000 for the corresponding period of 2020 primarily due to delays in procurement
actions and contract awards resulting primarily from the impact of COVID-19. The completion of a certain large project in the Services
Segment in the second quarter exacerbated the decrease in revenue. Revenue within our Treatment Segment decreased $134,000 or 1.7%. Our
Treatment Segment&#8217;s revenue has been negatively impacted by continued waste shipment delays from certain customers since the latter
part of the first quarter of 2020 at the start of the pandemic. However, we expect to see <span style="color: #252525">returns in waste
receipts from these customers starting in the second half of 2021. </span>Gross profit decreased $2,344,000 or 70.8% primarily due to
decreases in revenues in both segments as described above. Selling, General, and Administrative (&#8220;SG&amp;A&#8221;) expenses increased

Treatment and Services Segments&#8217; business continues to be heavily dependent on services that we provide to governmental clients,
primarily as subcontractors for others who are prime contractors to government entities or directly as the prime contractor. We believe
demand for our services will continue to be subject to fluctuations due to a variety of factors beyond our control, including, without
limitation, the economic conditions, the manner in which the applicable government will be required to spend funding to remediate various
sites, and/or the impact resulting from COVID-19 as discussed above. In addition, our governmental contracts and subcontracts relating
to activities at governmental sites in the United States are generally subject to termination or renegotiation on 30 days&#8217; notice
at the government&#8217;s option, and our governmental contracts/task orders with the Canadian government authorities allow the authorities
to terminate the contract/task orders at any time for convenience. Significant reductions in the level of governmental funding or specifically
mandated levels for different programs that are important to our business could have a material adverse impact on our business, financial
position, results of operations and cash flows. As previously disclosed, our Medical Segment has not generated any revenues and has substantially
reduced its R&amp;D costs and activities due to the need for capital to fund such activities. We anticipate that our Medical Segment
will not resume full R&amp;D activities until it obtains the necessary funding through obtaining its own credit facility or additional
equity raise or obtaining new partners willing to fund its R&amp;D activities. If the Medical Segment is unable to raise the necessary
capital, the Medical Segment could be required to further reduce, delay or eliminate its R&amp;D program.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">Treatment Segment revenue decreased $134,000 or 1.7% for the three months
ended June 30, 2021 over the same period in 2020. The revenue decrease was attributed primarily to lower revenue from government waste
generators resulting from lower waste volume. The increase in hazardous/non hazardous waste was primarily due to higher averaged price
waste. Our Treatment Segment revenue has been negatively impacted by continued waste shipment delays from certain customers since the
latter part of the first quarter of 2020 at the start of the COVID-19 pandemic. Services Segment revenue decreased by approximately $5,768,000
or 40.6%. As previously disclosed, our Services Segment revenue for the second quarter was impacted primarily by delays in procurement
actions and contract awards resulting from the impact of COVID-19. Our Services Segment revenues are project based; as such, the scope,
duration and completion of each project vary. As a result, our Services Segment revenues are subject to differences relating to timing
and project value.</span></p>

Segment revenue decreased $2,202,000 or 12.7 % for the six months ended June 30, 2021 over the same period in 2020 primarily due to lower
waste volume. As previously disclosed, since the latter part of the first quarter of 2020 at the start of the pandemic, revenue within
our Treatment Segment has been impacted by waste shipment delays from certain customers primarily due to the impact of COVID-19. Within
our Treatment Segment, revenue generated from other nuclear waste increased primarily due to higher waste volume generated from commercial
customers. Services Segment revenue decreased $5,427,000 or 18.4% for the six months ended June 30, 2021 over the same period in 2020.
As previously disclosed, our Services Segment revenue for the first six months of 2021 was impacted by delays in procurement actions
and contract awards resulting primarily from the impact of COVID-19. Also, our Services Segment revenues are project based; as such,
the scope, duration and completion of each project vary. As a result, our Services Segment revenues are subject to differences relating
to timing and project value.</span></p>

of goods sold for the Treatment Segment increased by approximately $128,000 or 2.1%. Treatment Segment&#8217;s variable costs increased
by approximately $136,000 primarily in disposal, transportation, material and supplies and outside services. Treatment
Segment&#8217;s overall fixed costs were slightly lower by approximately $8,000 resulting from the following: payroll related expenses
were lower by approximately $54,000; maintenance expenses were lower by $54,000; general expenses were higher by $52,000 in various categories;
depreciation expenses were higher by approximately $35,000 due to more financed leases; and travel expenses were higher by approximately
$13,000 due to ease of travel restrictions since the start of the pandemic. Services Segment cost of goods sold decreased $3,686,000
or 29.3% primarily due to lower revenue. The decrease in cost of goods sold was primarily due to lower salaries/payroll related, travel,
and outside services expenses totaling approximately $3,177,000 with the remaining lower costs in material and supplies, disposal, regulatory,
and general expenses. Included within cost of goods sold is depreciation and amortization expense of $394,000 and $358,000 for the three
months ended June 30, 2021, and 2020, respectively.</span></p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"><span style="font: 10pt Times New Roman, Times, Serif">Cost
of goods sold for the Treatment Segment decreased by approximately $120,000 or 0.9%. Treatment Segment&#8217;s variable costs decreased
by approximately $289,000 primarily in disposal, transportation, material and supplies and outside services due to lower revenue. Treatment
Segment&#8217;s overall fixed costs were higher by approximately $169,000 resulting from the following: general expenses were higher
by $171,000 in various categories; depreciation expenses were higher by approximately $80,000 due to more financed leases; regulatory
expenses were higher by approximately $23,000; maintenance expenses were lower by $89,000; and travel expenses were lower by $16,000
due to restrictions implemented from the impact of COVID-19. Services Segment cost of goods sold decreased $2,881,000 or 11.1% primarily
due to lower revenue. The decrease in cost of goods sold was primarily due to lower salaries/payroll related, travel, and outside services
expenses totaling approximately $2,082,000 with the remaining lower costs in material and supplies, disposal, regulatory, and general
expenses. Included within cost of goods sold is depreciation and amortization expense of $787,000 and $699,000 for the six months ended
June 30, 2021, and 2020, respectively.</span></p>

overall increase in SG&amp;A was primarily within our Services Segment where SG&amp;A expenses increased by approximately $268,000. The
increase in SG&amp;A expenses within our Services Segment was primarily due to the following: salaries and payroll related expenses were
higher by approximately $185,000 primarily due to increased hours spent for bid and proposals and higher healthcare costs; travel expenses
were higher by approximately $12,000 due to ease of travel restrictions since the start of the pandemic; outside services expenses were
higher by approximately $92,000 primarily due to more consulting matters related to bid and proposals; and general expenses were lower
by approximately $21,000. Administrative SG&amp;A expenses were slightly lower primarily due to the following: payroll related expenses
were lower by approximately $98,000 primarily due to forfeiture of 401(k) plan matching funds contributed by us for former employees
who failed to meet the 401(k) plan vesting requirements; director fees were higher by approximately $60,000 resulting from one additional
director and fee increases that went into effect January 1, 2021; travel expenses were higher by approximately $13,000 due to ease of
travel restrictions since the pandemic; outside services expenses were higher by approximately $14,000 resulting from more consulting/subcontract/legal
matters; and general expenses were slightly higher by approximately $6,000. Treatment Segment SG&amp;A expenses were higher due to the
following: bad debt expenses were higher by approximately $69,000 as in the second quarter of 2020, certain customer accounts which had
previously been reserved for were collected; travel expenses were slightly higher by approximately $5,000 due to ease of travel restrictions
since the start of the pandemic; general expenses were slightly higher by approximately $10,000; and salaries and payroll related expenses
were lower by approximately $50,000. Included in SG&amp;A expenses is depreciation and amortization expense of $6,000 and $6,000 for
the three months ended June 30, 2021, and 2020, respectively.</span></p>

overall increase in SG&amp;A was primarily within our Services Segment where SG&amp;A expenses increased by approximately $616,000. The
increase in SG&amp;A expenses within our Services Segment was primarily due to the following: salaries and payroll related expenses were
higher by approximately $371,000 primarily due to increased hours spent for bid and proposals; outside services expenses were higher
by approximately $192,000 due to more consulting matters related to bid and proposals; bad debt expenses were higher by approximately
$40,000 as in the first quarter of 2020, certain customer accounts which had previously been reserved for were collected; and general
expenses were slightly higher by $13,000. Administrative SG&amp;A expenses were slightly higher primarily due to the following: director
fees were higher by approximately $119,000 resulting from one additional director and fee increases that went into effect January 1,
2021; general expenses were slightly higher by approximately $5,000; payroll related expenses were lower by approximately $79,000 primarily
due to forfeiture of 401(k) plan matching funds contributed by us for former employees which failed to meet the 401(k) plan vesting requirements;
travel expenses were lower by approximately $10,000 due to less travel due to COVID-19; and outside services expenses were lower by approximately
$28,000 resulting from fewer consulting/subcontract/legal matters. Treatment Segment SG&amp;A expenses were lower due to the following:
travel expenses were lower by approximately $44,000 due to less travel resulting from COVID-19; general expenses were lower by $101,000
in various categories; bad debt expenses were higher by approximately $50,000 as in the second quarter of 2020, certain customer accounts
which had previously been reserved for were collected; salaries and payroll related expenses were higher by approximately $36,000 due
to increased hours spent on bid and proposals and higher healthcare costs; and outside services expenses were higher by approximately
$11,000 primarily due to more consulting matters. Included in SG&amp;A expenses is depreciation and amortization expense of $12,000 and
$12,000 for the six months ended June 30, 2021 and 2020, respectively.</span></p>

primarily financed by our operations, cash on hand and credit facility availability. Subject to the impact of COVID-19 as discussed above,
our cash flow requirements for the next twelve months will consist primarily of general working capital needs, scheduled principal payments
on our debt obligations, remediation projects, and planned capital expenditures. We plan to fund these requirements from our operations,
credit facility availability, our capital expenditure line, cash on hand and, if deemed appropriate, other sources available to us. We
are continually reviewing operating costs and reviewing the possibility of further reducing operating costs and non-essential expenditures
to bring them in line with revenue levels, when necessary. At this time, we believe that our cash flows from operations, our available
liquidity from our credit facility, our capital expenditure line and our cash on hand should be sufficient to fund our operations for
the next twelve months. However, due to the uncertainty of COVID-19, continued delays in waste shipments from certain customers, delays
in procurement actions and contract awards, and/or certain reserves that our lender has placed (see the amendment that we entered into
with our lender in August 2021 in &#8220;Financing Activities&#8221; below) or may place in the future against our revolving line of credit,
there are no assurances such will be the case. <span style="color: #252525">As a result, we continue to explore all sources, including,
but not limited to, selling additional stock of ours under our currently effective shelf registration, to increase our capital or supplement
our liquidity requirements and working capital. </span>As previously disclosed, our Medical Segment, which has not generated any revenues,
has substantially reduced its R&amp;D costs and activities due to the need for capital to fund such activities. We continue to seek various
sources of potential funding for our Medical Segment. We anticipate that our Medical Segment will not resume full R&amp;D activities until
it obtains the necessary funding through obtaining its own credit facility or additional equity raise or obtaining new partners willing
to fund its R&amp;D activities. If the Medical Segment is unable to raise the necessary capital, the Medical Segment could be required
to further reduce, delay or eliminate its R&amp;D program.</span></p>

Flexibility Act provides employers the option to defer the payment of an employer&#8217;s share of social security taxes beginning on
March 27, 2020 through December 31, 2020, with 50% of the amount of social security taxes deferred to become due on December 31, 2021
with the remaining 50% due on December 31, 2022. We elected to defer such taxes starting in mid-April 2020. At June 30, 2021, we have
deferred payment of approximately $1,252,000 in our share of social security taxes, of which approximately $626,000 is included in &#8220;Other

Customers</i>. Our Treatment and Services Segments have significant relationships with the U.S and Canadian governmental authorities
through contracts entered into indirectly as subcontractors for others who are prime contractors or directly as the prime contractor
to government authorities. As stated previously, our governmental contracts and subcontracts relating to activities at governmental sites
in the United States are generally subject to termination or renegotiation on 30 days&#8217; notice at the government&#8217;s option,
and our governmental contracts/task orders with the Canadian government authorities allow the authorities to terminate the contract/task
orders at any time for convenience. Our inability to continue under existing material contracts that we have with the U.S government
and Canadian government authorities (directly or indirectly as a subcontractor) or significant reductions in the level of governmental
funding in any given year could have a material adverse impact on our operations and financial condition.</span></p>

performed services relating to waste generated by government clients (domestic and foreign (primarily Canadian)), either directly as
a prime contractor or indirectly for others as a subcontractor to government entities, representing approximately $13,671,000 or 84.7%

Impact.</i> The extent of the impact of the COVID-19 pandemic on our business continues to be uncertain and difficult to predict, as
the responses to the pandemic continue to evolve rapidly. We continue to experience delays in waste shipments from certain customers
within our Treatment Segment primarily related to the impact of COVID-19. However, we expect to see returns in waste receipts
from these customers in the second half of 2021. Within our Services Segment, we continue to experience delays in procurement actions
and contract awards resulting primarily from the impact of COVID-19 but have recently begun to receive contract awards. We expect procurement
actions and contract awards to continue throughout the second half of 2021. Within our Treatment and Services Segments, we have an unprecedented
number of bids currently submitted and awaiting awards.</span></p>

severity of the impact the COVID-19 pandemic on our business will depend on a number of factors, including, but not limited to, the duration

the impact on governmental programs and budgets, inoculation rate of the vaccines, and how quickly and to what extent normal economic
and operating conditions resume, all of which are uncertain and cannot be predicted with any accuracy or confidence at this time. Our
future results of operations and liquidity could be adversely impacted from continued delays in waste shipments, continued delays in
procurement actions and contract awards, and/or recurrence of project work shut downs as well as potential partial/full shutdown of any
of our facilities due to COVID-19. </span></p>

These regulations mandate strict compliance and therefore are a cost and concern to us. Because of their integral role in providing quality
environmental services, we make every reasonable attempt to maintain complete compliance with these regulations; however, even with a
diligent commitment, we, along with many of our competitors, may be required to pay fines for violations or investigate and potentially
remediate our waste management facilities.</span></p>

consolidated financial statements included herein have been prepared by the Company (which may be referred to as we, us or our), without
an audit, pursuant to the rules and regulations of the Securities and Exchange Commission (&#x201c;the Commission&#x201d;). Certain information

the Company believes the disclosures which are made are adequate to make the information presented not misleading. Further, the consolidated
financial statements reflect, in the opinion of management, all adjustments (which include only normal recurring adjustments) necessary
to present fairly the financial position and results of operations as of and for the periods indicated. The results of operations for
the six months ended June 30, 2021 are not necessarily indicative of results to be expected for the fiscal year ending December 31, 2021.&lt;/span&gt;&lt;/p&gt;

those fiscal years, beginning after December 15, 2020, with early adoption permitted. The adoption of ASU No. 2019-12 by the Company

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: black"&gt;In June 2016, the FASB issued ASU No. 2016-13, &#x201c;Credit Losses
(Topic 326) - Measurement of Credit Losses on Financial Instruments,&#x201d; and various subsequent amendments to the initial guidance
(collectively, &#x201c;Topic 326&#x201d;). Topic 326 introduces an approach, based on expected losses, to estimate credit losses on certain
types of financial instruments and modifies the impairment model for available-for-sale debt securities. The new approach to estimating
credit losses (referred to as the current expected credit losses model) applies to most financial assets measured at amortized cost and
certain other instruments, including trade and other receivables and loans. Entities are required to apply the standard&#x2019;s provisions
as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted.
In November 2019, FASB issued ASU 2019-10, &#x201c;Financial Instruments &#x2013; Credit Losses (Topic 326), Derivatives and Hedging (Topic
815), and Leases (Topic 842),&#x201d; which defers the effective date of ASU 2016-13 for public companies that are considered smaller reporting
companies as defined by the Commission to fiscal years beginning after December 15, 2022, including interim periods within those fiscal
years. These ASUs are effective January 1, 2023 for the Company as a smaller reporting company (&#x201c;SRC&#x201d;). Under new guidance
issued by the Commission in March 2020, the Company will continue to qualify as a smaller reporting company but will also be an accelerated
filer for all filings with the Commission after January 1, 2022. The Company is currently evaluating the impact of these ASU on its consolidated
financial statements.&lt;/span&gt;&lt;/p&gt;

by removing major separation models and removing certain settlement condition qualifiers for the derivatives scope exception for contracts
in an entity&#x2019;s own equity, and simplifies the related diluted net income per share calculation for both Subtopics. ASU 2020-06
is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023, for the Company as a
smaller reporting company. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including

stock options granted include the exercise price of the award, the expected term, the expected volatility of the Company&#x2019;s stock
over the option&#x2019;s expected term, the risk-free interest rate over the option&#x2019;s expected term, and the expected annual dividend
yield. The fair value of the options granted on May 4, 2021 as discussed above and the related assumptions used in the Black-Scholes
option model used to value the options granted were as follows:&lt;/span&gt;&lt;/p&gt;

income per share is calculated based on the weighted-average number of outstanding common shares during the applicable period. Diluted
income per share is based on the weighted-average number of outstanding common shares plus the weighted-average number of potential outstanding
common shares. In periods where they are anti-dilutive, such amounts are excluded from the calculations of dilutive earnings per share.
The following table reconciles the income and average share amounts used to compute both basic and diluted income per share:&lt;/span&gt;&lt;/p&gt;

all commitments to extend further credit. The Company met its financial covenant requirements in the first quarter of 2021. The Company&#x2019;s

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;During
July 2020, Tetra Tech EC, Inc. (&#x201c;Tetra Tech&#x201d;) filed a complaint in the United States District Court for the Northern District
of California (the &#x201c;Court&#x201d;) against CH2M Hill, Inc. (&#x201c;CH2M&#x201d;) and four subcontractors of CH2M, including the Company
(&#x201c;Defendants&#x201d;). The complaint alleges claims for negligence, negligent misrepresentation and equitable indemnification against
all defendants related to alleged damages suffered by Tetra Tech in respect of certain draft reports prepared by defendants at the request
of the U.S. Navy as part of an investigation and review of certain whistleblower complaints about Tetra Tech&#x2019;s environmental restoration
at the Hunter&#x2019;s Point Naval Shipyard in San Francisco.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

was hired by the Navy in 2016 to review Tetra Tech&#x2019;s work. CH2M subcontracted with environmental consulting and cleanup firms Battelle
Memorial Institute, Cabrera Services, Inc., SC&amp;amp;A, Inc. and the Company to assist with the review, according to the complaint.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; color: #2B2B2B; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif; color: Black"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

complaint alleges that the subject draft reports were prepared negligently and in a biased manner, made public, and caused damage to
Tetra Tech&#x2019;s reputation; triggering related lawsuits and costing it opportunities for both government and commercial contracts.&lt;/span&gt;&lt;/p&gt;

January 7, 2021, Defendants&#x2019; motion to dismiss the complaint in its entirety was granted without prejudice, with leave to amend.
Tetra Tech subsequently filed a First Amended Complaint (&#x201c;FAC&#x201d;) and Defendants filed a motion to dismiss Tetra Tech&#x2019;s
FAC. Tetra Tech filed an opposition to Defendant&#x2019;s motion to dismiss Tetra Tech&#x2019;s FAC. Defendants, subsequently filed a joint
reply to Tetra Tech&#x2019;s motion in opposition. A decision and Order on Defendants&#x2019; motion to dismiss is pending from the Court.
At this time, the Company continues to believe it does not have any liability to Tetra Tech.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company and Engineering/Remediation Resources Group, Inc. (&#x201c;ERRG&#x201d;) previously entered into an unpopulated joint venture agreement
for project work bids within the Company&#x2019;s Services Segment with the joint venture doing business as Perma-Fix ERRG, a general
partnership. The Company has a &lt;span id="xdx_90D_eus-gaap--VariableInterestEntityOwnershipPercentage_pid_dp_c20210101__20210630_zZgxhK2bT1A9" title="Partnership interest rate"&gt;51%&lt;/span&gt; partnership interest in the joint venture and ERRG has a &lt;span id="xdx_903_eus-gaap--VariableInterestEntityOwnershipPercentage_pid_dp_c20210101__20210630__dei--LegalEntityAxis__custom--EngineeringRemediationResourcesGroupIncMember_zMkvdevoav5i" title="Partnership interest rate"&gt;49%&lt;/span&gt; partnership interest in the joint venture.

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company determines whether joint ventures in which it has invested meet the criteria of a VIE at the start of each new venture and when
a reconsideration event has occurred. A VIE is a legal entity that satisfies any of the following characteristics: (a) the legal entity
does not have sufficient equity investment at risk; (b) the equity investors at risk as a group, lack the characteristics of a controlling
financial interest; or (c) the legal entity is structured with disproportionate voting rights. &lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;The
Company consolidates a VIE if it is determined to be the primary beneficiary of the VIE. The primary beneficiary has both the power to
direct the activities of the VIE that most significantly impact the entity&#x2019;s economic performance and the obligation to absorb
losses or the right to receive benefits from the VIE that could potentially be significant to the VIE.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font-family: Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;Based
on the Company&#x2019;s evaluation of Perma-Fix ERRG and related agreements with Perma-Fix ERRG, the Company determined that Perma-Fix
ERRG continues to be a VIE in which the Company is the primary beneficiary. At June 30, 2021, Perma-Fix ERRG had total assets of $&lt;span id="xdx_90D_eus-gaap--Assets_iI_pn3n3_c20210630__dei--LegalEntityAxis__custom--PermaFixERRGMember_zRks1en8mEEc" title="Total assets"&gt;2,528&lt;/span&gt;,000

(Topic 326) - Measurement of Credit Losses on Financial Instruments,&#8221; and various subsequent amendments to the initial guidance
(collectively, &#8220;Topic 326&#8221;). Topic 326 introduces an approach, based on expected losses, to estimate credit losses on certain
types of financial instruments and modifies the impairment model for available-for-sale debt securities. The new approach to estimating
credit losses (referred to as the current expected credit losses model) applies to most financial assets measured at amortized cost and
certain other instruments, including trade and other receivables and loans. Entities are required to apply the standard&#8217;s provisions
as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted.
In November 2019, FASB issued ASU 2019-10, &#8220;Financial Instruments &#8211; Credit Losses (Topic 326), Derivatives and Hedging (Topic
815), and Leases (Topic 842),&#8221; which defers the effective date of ASU 2016-13 for public companies that are considered smaller reporting
companies as defined by the Commission to fiscal years beginning after December 15, 2022, including interim periods within those fiscal
years. These ASUs are effective January 1, 2023 for the Company as a smaller reporting company (&#8220;SRC&#8221;). Under new guidance
issued by the Commission in March 2020, the Company will continue to qualify as a smaller reporting company but will also be an accelerated
filer for all filings with the Commission after January 1, 2022. The Company is currently evaluating the impact of these ASU on its consolidated
financial statements.</span></p>

by removing major separation models and removing certain settlement condition qualifiers for the derivatives scope exception for contracts
in an entity&#8217;s own equity, and simplifies the related diluted net income per share calculation for both Subtopics. ASU 2020-06

15, 2020, with early adoption permitted. The adoption of ASU No. 2020-01 by the Company effective January 1, 2021 did not have a material
impact on the Company&#8217;s financial statements or disclosures. </span></p>

(Topic 326) - Measurement of Credit Losses on Financial Instruments,&#8221; and various subsequent amendments to the initial guidance
(collectively, &#8220;Topic 326&#8221;). Topic 326 introduces an approach, based on expected losses, to estimate credit losses on certain
types of financial instruments and modifies the impairment model for available-for-sale debt securities. The new approach to estimating
credit losses (referred to as the current expected credit losses model) applies to most financial assets measured at amortized cost and
certain other instruments, including trade and other receivables and loans. Entities are required to apply the standard&#8217;s provisions
as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted.
In November 2019, FASB issued ASU 2019-10, &#8220;Financial Instruments &#8211; Credit Losses (Topic 326), Derivatives and Hedging (Topic
815), and Leases (Topic 842),&#8221; which defers the effective date of ASU 2016-13 for public companies that are considered smaller reporting
companies as defined by the Commission to fiscal years beginning after December 15, 2022, including interim periods within those fiscal
years. These ASUs are effective January 1, 2023 for the Company as a smaller reporting company (&#8220;SRC&#8221;). Under new guidance
issued by the Commission in March 2020, the Company will continue to qualify as a smaller reporting company but will also be an accelerated
filer for all filings with the Commission after January 1, 2022. The Company is currently evaluating the impact of these ASU on its consolidated
financial statements.</span></p>

and Hedging &#8211; Contracts in Entity&#8217;s Own Equity.&#8221; ASU 2020-06 simplifies the accounting for convertible instruments
by removing major separation models and removing certain settlement condition qualifiers for the derivatives scope exception for contracts
in an entity&#8217;s own equity, and simplifies the related diluted net income per share calculation for both Subtopics. ASU 2020-06
is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023, for the Company as a
smaller reporting company. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including
interim periods within those fiscal years. The Company is currently evaluating the impact of this ASU on its consolidated financial statements

Flexibility Act provides employers the option to defer the payment of an employer&#8217;s share of social security taxes beginning on
March 27, 2020 through December 31, 2020 with 50% of the amount of social security taxes deferred to become due on December 31, 2021
with the remaining 50% due on December 31, 2022. The Company elected to defer such taxes starting in mid-April 2020. At June 30, 2021,
the Company has deferred payment of approximately $1,252,000 in its share of social security taxes, of which approximately $626,000 is
